1. Identifying Business ideas for productive use of RE in Botswana

1.1 Process of identifying project ideas: Some of the initial business ideas had to be abandoned because they did reveal not

to be financially or technically feasible. For example the possibility of installing a solar

water pump in a horticulture project operated by a women’s group was considered.

Unfortunately this was not pursued further as CEDA, the then the only financing

partner in the project (as a member of IAT), does not finance projects owned by

cooperative organizations.

Another ideas followed was an Ostrich farm in Molepolole. However, it has been

established that the energy demand for this project is beyond the capability of solar

energy. The farm uses an incubator for hatching eggs. The farm has no electricity (it

would cost about 375K to connect to the grid) and as a result the incubator is kept in

the nearest village, Molepolole which is about 5km away.

It has been noted that INSABA services need to be marketed rigorously in the

country for entrepreneurs to consider RETs as useful alternatives to conventional

power. Although INSABA-BOTSWANA was advertised in both the media, responses

received were quite low. New partners like the Board of Trade and other vocational

training institutions should be involved.

1.2 Development of business plans After some of the initial business ideas had to be abandoned for reasons as those

mentioned above, business plans have been developed with support if the IA Gerrit

Jacobs from Solar International Botswana. In order to systematically assess the

potential of business ideas, BOTEC developed project descriptions on business

ideas like barber shop, pay-phone charging, vegetable farm with irrigation, tourist

lodge with SWH, battery charging station, chicken farm lighting and PV pumping for

cattle farm. These business ideas were then discussed with potential SME-GS and

data were collected from existing businesses such as horticulture, barber shop, pay

phone. From this information complete business plans have been prepared for the

productive use of renewable energy in:

- Mobile photo & printing shop

- barber shop

- payphone charging

- vegetable farm with irrigation

- Khutse lodge with SWH

- Mobile fruit juice vendor

The development of business plans was considered a breakthrough. The plans

indeed support the concept of productive use of RETs.

1.3 Financing of business ideas Many of the potential businesses assessed during the project would have been

involved in INSABA related projects if funding to purchase RETs systems was readily

available, particularly for very small businesses that require loans less than €1000.

It is understood that financial support is vital for any economic activity and that is why

there are banks and other financial institutions in place. This is mainly true, however,

for small and even medium enterprises because most of them start economic

activities for the first time (Start ups). Generally in most developing countries no

financial institutions are ready to give loans to small and medium sized start-up

enterprises. That is why financial considerations are generally part of RE-strategies.

1.4 Implementation of business plans From all the INSABA-Botswana accepted business, only one i.e. the “Photoshop”

was realized in time e.g. before the official end of the INSABA-projects. The mobile

photo business, which is operating from the bus rank, has been Botswana’s INSABA

success story. The entrepreneur has now started to pay back the loan he acquired to

purchase the photo and solar PV equipment.

It can be stated however, that all projects are very likely to be put in action still 2008

or latest 2009.

The irrigation project could not be realized, because solar pumping presented

physical barriers to the project, but this, by no means, does not mean that Solar

Irrigation will not applied when better conditions are present e.g. a ground-water table

below 100 m.

The INSABA Fresh Fruit Juice Business was stopped by municipal authorities, as

sale of fresh food produced in the street for public consumption is not allowed for

health reasons. Though that type of business is quite frequent in other countries, it

can not be realized in Botswana for the time being.

1.5 RE Technologies in business ideas One can observe a certain concentration by INSABA-Botswana on Solar-Energy

applications. This can be explained by the fact that solar applications are currently

the most supported and mature renewable energy applications in Botswana. From

the group of IATs, INSABA-Botswana worked closely together with the enterprise

Solar International Botswana (SIB) (Pty.) Ltd.

The circumstances are relatively obvious because Botswana is a relatively dry

country where Solar Energy applications have a fair chance in the local energy

market. Furthermore SIB advised INSABA-Zambia as consultant. This intervention is

understood by InWEnt as one of the INSABA success-stories. Additionally a very

fruitful cooperation between Botswana and Namibia started on the Solar-Energy field

as one further positive element in the South-South Cooperation.

Botswana has started investigations in the Biomass-sector1. Jatropha is a topic, but

might have few chances due to high water demand. Probably other autochthones oil-

containing plants may have a better chance to be used as bio-fuel.

1.6 Replication Replication is important for INSABA type of projects. This could be possible if there

are several businesses that are running that other entrepreneurs can copy from.

Entrepreneurs should be encouraged to advise other entrepreneurs. It is very difficult

for individuals and organisations that do not, for instance, have vested interest such

as suppliers or manufacturers, to mentor entrepreneurs.

Organisations such as the Local Enterprise Authority should be lobbied to integrate

INSABAs way of business analysis in their functions. This would go a long way in

marketing the use of Renewable in businesses. BOTEC and Solar International

Botswana could lead this task.

BOTEC will also lead production of a manual with tools, who entrepreneurs can

contact for advice and where the advisors can be located. This will require advising

institutions to commit themselves that they will be available to assist entrepreneurs.

Mobile Photo Shop Business Proposal

Business DescriptionMobile Photo Shop business

ProponentArnold Tshwaranang Moleofi is a young motivated entrepreneur who is interested in running amobile photo shop business. He has undergone a Business Studies course and has started acar wash financed through own resources, which is run by family members. He does not have abank account but is considering opening one. Mr. Moleofi has no experience with formal loansbut is well acquainted with cost calculations and marketing since this was part of hisprofessional training.

LocationThe photo shop business is mobile and can be located at shopping malls, bus ranks, trainstations, public and sporting events and other locations where there is a likely market for sellingphotos.

Business FactorsIn Botswana there are no mobile photo shops. Photoshops operate from fixed locations in town centres.However, there are people with instant cameras thatmainly take passport photograph size photos.

The proposed mobile photo shop consists of a digitalcamera and a printer/copier/scanner, which arelocated in a mobile stall. Photos are taken and are printed at the spot. The camera connectsdirectly to the printer, so there is no need for a computer. Other services that are provided areindicated in the box on the right.

Since the business operation is entirely mobile, it can besituated at a location where the market potential is highest. Theequipment is powered from a solar panel and battery.Measurements of the printer show that the power consumptionwhen printing is approximately 300W and when on standby it isapproximately 25W. One 50Wp panel and one 100Ah batteryare sufficient to power the printer. The photos are laminatedusing plastic foil, rather than a thermal process because of thelimited energy that is available from the solar system.

The primary business activity is taking photos. However, theprinter has copying and scanning capabilities, therefore theseservices are also offered.

The photographer will offer different backgrounds for photossuch as the Eiffel Tower and Statue of Liberty when takingphotos. There will also be life size cut-out pictures of popularsoccer and movie stars.

Pre-AssessmentThe general feasibility of the business idea is established in a pre-feasibility assessment. Anestimation of business requirements and costs is given in the following sections.

Inventory: P1,310 Stall on wheels, chair, umbrella, stand, studio curtains, life sizecut-outs

Equipment: P2,770 Camera and printer/copier, memory card, camera stand

Solar system: P3,660 1x 50Wp solar panel, 1x100Ah battery, Regulator, AA Batterycharger, Inverter

Advertisingmaterial:

P1,200 Advertising display, price list, business cards

Total equipment cost is P8,940. Furthermore, there are variable costs such photo paper,photocopying paper, laminating foil, and printing ink.

Production:A quick estimation of the required number of photos is based on the following parameters.

The highlighted parameters are variables. The expense per photo is an estimate. Based on theabove figures, the operator has to sell 14 photos per day (300 days per year) to cover expensesand pay back the investment.

Operational expenses:� Variable costs that are accounted for in the unit cost.� Storage space is rented for the equipment. Estimated costs P50/month.� The salary of the operator is P1000/month.� Insurance of equipment is P110/month.

Investment live span is taken as 5 years. The solar panels have an estimated life span of 20years but the other equipment such as the camera and printer have a life span which isconsiderably less.

Table1 (pre-assessment) contains all above data. Sensitivity analysis using data in Table 1shows the impact of the various cost factors. Most sensitive elements are price per unit and costper unit. A sensitivity analysis has been carried out using the goal seek function in Excel. Whenselling 10 photos per day, the payback period is 1 year with ROI of 80%, whereas selling 15photos per day gives a payback period of ½ year and ROI of 180%. However, selling 9 photosper day gives a ROI of 30% and a payback period of 2 years. It can be concluded that theproposed business has the potential of being profitable.

Operator income 1,000 P/month

Payback 750 P/month

Income to be generated 1,750 P/month

Days working per month 25 Days/month

Profit to be made per day 70 P/day

Selling price per photo 15 P/photo

Expenses per photo 10 P/photo

Profit per photo 5 P/photo

Photos to be made 14 Photos/day

Market AssessmentThere are currently no mobile photo shops operating in the country. Having a mobile photo shophas a great advantage over a shop that has a fixed location since a market can be establishedat a place where it has the highest potential for success e.g. near the National Stadium duringpopular football matches.

The entrepreneur has interviewed owners of photo shops to obtain an idea of possible turnoverand selling prices of photos. He has also interviewed persons that take photos with instantcameras and it appears that producing 10 photos per day with an average selling price of P15per photo is achievable.

Apart from being mobile, it is believed that this business format has another positive edgecompared to a business at a fixed location. Taking photos of people next to a life size cut-out of amovie star or soccer player will attract the attention of people and form a crowd, boosting thenumber of photos that are taken.

Table 2 shows a comparison between the photo business using a solar system and the samebusiness recharging the battery from grid electricity through a commercial operator. In thissituation there is a reduced investment capital since there is no solar equipment required. Alsothere is less equipment to insure and therefore the insurance cost goes down (P600/year).However, due to the deeper discharge of the battery and the higher boost charge from gridelectricity, the battery lifetime is reduced. This has been accounted for (annual replacement costP500, instead of P350). The cost of charging the battery, including transportation is estimated atP20 per charge. The comparison shows that it is more cost effective to charge the battery fromgrid electricity through a commercial operator. The higher ROI is caused by the reduced cost ofcharging the battery. The cost of the solar technology is much higher compared to the recurrentcost of charging the battery and therefore has a negative impact on the ROI. However, it shouldbe noted that charging the battery every two days is very cumbersome since the battery has tobe dropped off in the evening and collected in the morning. If not, two batteries are required. Alsothere are few places where batteries can be charged and transportation costs will be high andthere is an opportunity cost associated with the time that it takes to charge the batteries.

Operational PlanThe business strategy relies on the mobility of the business and the ability of printing photosinstantly. The business should be run in a professional manner in order to succeed. The operatorshould wear a branded uniform and the stall should look neat.

Table 3 gives the cash flow during the first three years of operation. The cash flow analysisindicates clearly, how much financing would be required. Under the prevalent conditions, capitalinfusion of P8,940 would be sufficient. The graphs visualize this business development for thefirst year, and for three years, respectively.

Note that making copies has been added as a second income stream.

Finally, Table 4 gives the profitability forecast and balance for the business start-up.

From the Sensitivity Analysis below it becomes clear that the average selling price of a photo,number of photos sold, as well as the variable cost, being the cost of photo paper, photocopypaper, laminating foil, and printing ink, are the most critical success/failure factors.

The higher ROI is caused by the reduced cost

of charging the battery. The cost of the solar

technology is much higher compared to the

recurrent cost of charging the battery and

therefor has a negative impact on the ROI.

However, it should be noted that charging the

battery every two days is very cumbersome

since the battery has to be dropped off in the

evening and collected in the morning. If not,

two batteries are required. Also there are few

places where batteries can be charged and

transportation costs will be high and there is an

opportunity cost associated with the time that it

Because the photo shop is powered by solar energy, it makes it mobile. Shop can

operate in villages where there is no grid electricity.

Photo shops with grid electricity may operate cheaper. Risk of RE system being stolen.

Ease of operation since there is no need for recharging the battery using grid electricity.

The shop is mobile.

Battery needs recycling but this also applies to system that does not use RE.

There are no mobile photo shops in Gaborone. Due to the mobility of the shop the

entrepreneur can go to places where the likelyhood of a sufficient market is highest.

This model can be replicated for any locations in Botswana, where there is sufficient

market. If more photos per day are required, an additional solar panel may be added to

supply the energy.

There is a risk that the Town Council will not allow the photo shop to operate at plublic

places.

There are a number of people operating with instant cameras. There is also cometition

from people working from fixed locations.

Business Proposal Barber Shop

Business DescriptionPayphone Business

ProponentMr. Moshe Makhweni has two years experience as the owner of the payphone business. Heoperates as the proprietor/operator and works part-time in the business. He has one employeewho works most of his time in the business. The business has a hawker’s license from theGaborone City Council. As such, the business obtained a free space that is registered with theCouncil. Mr. Makhweni has completed form five at Masunga Senior Secondary School. Hedoes not hold a bank or savings account and does not have experience in obtaining loans.

LocationThe payphone business is locates at the Main Mall in front of the Lewis store, in the centre ofGaborone. There is no mains electrical connection.

Business FactorsThe payphone business provides national and international phone services to the general public.A payphone is a telephone that operates on the cellular network and of which the operating costis monitored on a digital display.The customer that makes thephone call is charged per unit. Thepayphone operator buys the unitsfrom a representative of thecellular network provider. Sincethere are two cellular networkproviders in Botswana (Mascomand Orange), the operator has twodifferent sets of payphones. Thisis necessary since phoning fromone network to the other is morecostly than phoning within thesame network. Modern payphoneshave Mascom, as well as Orangesimcards incorporated that areaccessed automatically,depending on which network isdialed.The business is strategically located with high exposure to people shopping at the Main Mall. Thebusiness is situated under an umbrella that is provided by Masom. Apart from providing shade, itadvertises the business, since Mascom is a strong brand in Botswana.

The system uses a 45Ah car battery to supply power to the twopayphones. Large crocodile clips are used to connect the payphones tothe battery, which allows for reversing of the polarity. The uncoveredbattery is potentially dangerous and should be placed in an appropriatebox. The battery is very much oversized for the system and is old andbadly maintained. The battery is charged once every two weeks at a230VAC mains battery charging station, at a cost of P5.- (approx.US$0.90) per charge. The business does not have lights or a radioconnected to the battery, although this may attract additional customers.

Draft: 1 April 2007

Sales of Mascom and Orange scratch cards, and selling sweets and cigarettes generateadditional income.The business is open 6 days per week from approximately 9am to 18.00am

Pre-AssessmentThe payphone business is an existing and operational business. It has proven to be feasible andsustainable. This exercise serves as an assessment to determine if similar payphone businessesmay be feasible in other areas and to determine what the most important success and failurefactors may be.

From the operational experience, the following facts are known:

Cost of:� Inventory: P600 Chairs, table, umbrella with stand� Equipment: P3,500 Payphone systems� Solar system: P530 7Wp solar panel and battery

Production:� The average number of phone calls per day is estimated by the operator to be 50.� Price per phone call national: P1.- per unit, international P3.50 per unit.� No detailed records are kept of units sold and bought. However, it is known that the average

profit on the sale of units is P78 per day. Working backwards this gives an average incomeper phone call of P3.56.

Operational expenses:� The average cost per phone call is P2.-.� Storage space is rented for the chairs, table and umbrella. This costs P50/month.� The cost for repairs of the payphone system, handset, and bi-annual replacement of the

battery is estimated at P550 per year.� The salary of the employee is P750/month.� The owner does not work fulltime in the business. His salary is determined using the goal

seek function. His salary can be P950 per month for a ROI of 30%. However, this amountgenerates a negative cash flow in tool 3 since the cost of interest and redemption is takeninto account in this tool. Therefor the salary of the owner is taken as P750/month in tool 3.

The pre-assessment table1 contains all above data. Sensitivity analysis with table 1 shows theimpact of the various cost factors. Most sensitive elements are the cost per unit for the telephonecalls and the number of phone calls per annum.

Market AssessmentThe payphone business is operated in a sustainable way, since it has been in operation for twoyears. However, over the last years there has been a considerable increase in similar businessesand competition is fierce. About six more payphone businesses operate at the vicinity, over astretch of 500 meters at the Main Mall. It appears that the market in villages is under served.While most villages in Botswana have cellular network reception, there are not many payphonesoperational. The reason could be the lack of charging facilities for the battery. This is easilyovercome by using a small solar panel. Operating in villages has two benefits: due to lesscompetition there are more clients per payphone operator and the charges for the phone callscan be higher. From the financial analysis it can be observed that profitability is highly sensitiveto these factors. Since the payphone business if very mobile, operators can easily move toplaces where there is a better market potential. The payphone operator also sells forapproximately P400 scratch cards per day. The profit is 10% per card, which results in anadditional income of P40.- per day. Profit on the sales of sweets and cigarettes is approximatelyP10.- per day. Additional income may be generated by charging cellphones and smallrechargeable NiMeH batteries.

Table 2 shows a comparison between the payphone business using an RE system and the samebusiness recharging the battery from 230VAC mains electricity. The higher ROI for the latter iscaused by the reduced cost of charging the battery. The cost of the RE technology is muchhigher compared to the recurrent cost of charging the battery and therefor has a negative impacton the ROI.

Operational PlanIt appears that awareness regarding the possibility of charging batteries using a solar panel islacking with many payphone operators. Most entrepreneurs use a car battery that they chargeevery number of days. What is required is a product package that offers a the payphone systemtogether with one or two 12VDC lights, a 10Wp solar panel and a 20Ah battery with regulator,that can be offered to the potential users. Therefor what is necessary is:� awareness creation� technology package

Table 3 gives the cash flow during the first three years of operation. The cash flow analysis at thebottom of the table indicates clearly, how much financing would be required. Under the prevalentconditions, capital infusion of US$1000 would be sufficient. The graphs 4a and 4b visualize thisbusiness development for the first year, and for three years, respectively.Table 4 finally, gives the profitability forecast and balance for the business start-up.

Payphone businesses operate at almost every streetcorner in the centre of Gaborone.

Most often they use a car battery that is charged from the grid. Often operators are not

connected to the grid and charge the battery at a charging station. Competition in the

main centres is high. Large market available in villages. The same business model is

replicable for different parts of the country.

There is a risk that more and more people well own cellphones, reducinng the market

for payphone operators.

See above

See above

A smaller battery can be used, which is easier transportable. Also using RE a radio can

be operated and light, so that working hours are extended.

Payphone operators without RE system may operate cheaper, although the difference

is marginal. Risk of RE system being stolen

Better end result, faster, more comfort due to ventilation

Battery needs recycling but thsi also applies to system that does not use RE

Vegetable Farm using Drip Irrigation Business Proposal

Business DescriptionVegetable farm using drip irrigation

ProponentMrs. Sibanda has only one year experience as the owner of the vegetable farm named “KhodaAgencies”. She is assisted by a team from the National Masterplan for the Arable Agricultureand Dairy (Nampaad), who also developed the business plan for the vegetable farm. Mrs.Sibanda is chairlady of the Glenvaley farmers association. She managed to develop the farmand turn it into a profitable business within one year. She was a paid employee before shestarted the vegetable farm and has a diploma in marketing. The farm is financed through theCitizen Entrepreneurial Development Agency (CEDA) and has 6 employees.

LocationThe vegetable farm is located on the outskirts of Otse (55km from Gaborone), South-East ofthe village centre.

Business FactorsThe vegetable farm consists of threedistinct areas:� Open field with drip irrigation� Net house with drip irrigation� Covered area with hydroponics

The open field (see photo on the right)consists of 3 hectares and different cropsare grown such as onion and cabbage.There are two boreholes at the farmwhich are approximately 160m deep.The water is pumped into a reservoir(see photo on the right).

The net house has an area of 1 hectare.A wide range of vegetables are grown inthe net house such as bell peppers,lettuce, spinach, broccoli, beetroot,eggplant and cauliflower.

The covered area totals 0.5 hectare,where tomatoes are grown usinghydroponics. Most hydroponics systemscomprise of beds or pots that are filledwith an inert substrate, or growingmedium such as vermiculite or sawdust,which replaces soil to hold plant rootsand moisture. A liquid nutrient solutionruns through the beds to feed the roots.The roots are always kept moist, but areaired periodically so they do not rot.Water is circulated and nutrient levelsare closely monitored and added asrequired for optimum plant growth.

Draft: 6 August 2007

At the left of the field are onions, at theback are cabbages and the drip irrigationsystem can be seen at the right

Water storage of 185.000 litres

The farm is connected to the mains electric grid and uses electricity for pumping water into astorage tank, operating booster pumps for drip irrigation and pressure pumps for the hydroponicssystem and for lighting. This case study compares the use of grid electricity with solar PVelectricity for pumping water using drip irrigation to grow cabbage in the open field. Calculationsfor other vegetables are similar. Growing of vegetables in the net house and hydroponically werenot considered due to lack of information regarding some of the parameters that are required forthe calculations. These farming techniques are also not as easy to replicate due to the largercapital investment and complexity of operation, such as in the case of hydroponics.

Pre-AssessmentThe vegetable farm is an existing and operating business. It has proven to be feasible. Thisexercise serves as an assessment to determine if similar vegetable farms may be feasible usingsolar PV for water pumping and to determine the most important success and failure factors.Only growing cabbage in open field using drip irrigation is considered for the case study. Thegrowing season for cabbage is 3 months and 4 crops can be harvested during the year. For easeof comparison, calculations are carried out for one hectare. From working experience andrecords that were kept, the following parameters are known:

Cost of equipping the borehole and irrigation system per hectare: P88,714

Cold room, office and office equipment: P14,250

Drilling of the borehole and pump: P49,120

Storage tank (370.000 litres). This is double the size compared topumping with grid electricity to cover for cloudy days:

P42,500

Cost of solar PV array for solar pump with head of 50m, 90m3/day

and P35/Wp:P121,092

Small truck: P200,000

Average kg cabbages per year (20% production losses): 224,000 kg

Average price of cabbage per kg: P1.62

Wages labourers and manager: P11,700

Insurance per year: P800

Ploughing per ha per year: P1,200

Vehicle maintenance cost per year: P10,000

Based on these figures a Pre-Assessment of the vegetable farm using drip irrigation with solarPV was carried out. Results are shown in Table 1. Also calculations were carried out comparinggrid electricity with PV solar electricity. Results of this assessment are shown in Table 2.

Table 3 below shows a comparison between the two sources of energy.

Solar PV Electricity GridElectricity

ROI 44% 63%

Paybackperiod (yrs) 1.81 1.35

It can be observed that growing vegetables in both cases is highly profitable. The largeinvestment for the solar panels has a limited impact on the ROI. The reason for this can beobserved from the sensitivity analysis below Table 3. The cost of energy/unit has only a limitedinfluence on the change of ROI.

Market AssessmentMost of the vegetables are sold to the supermarketchains in Gaborone. Limited amounts are sold from thefarm to local customers. The vegetables aretransported in a small truck (bakkie). Since Mrs.Sibanda resides in Gaborone, she drives backward andforward between Otse and Gaborone and takes loadsof vegetables with her. There is not a plannedmarketing strategy and marketing is mostly donethrough word-of-mouth. The demand is currently higherthan supply therefore there are no problems selling thevegetables the market. Late payments for the sales ofvegetables sometimes cause problems.

Seedlings are bought and readily available. To reducecosts, the farm will grow their own seedlings from seedsfor most vegetables in the future.

The cost of chemicals and fertilisers is perceived as very high and it was expressed thatgovernment should subsidise these items to help farmers.

Operational PlanThe vegetable farm managed to develop into a successful business within a year, mainly due theenergetic input from Mrs. Sibanda. Although she did not have any prior farming experience, shestarted the business, and through her background in marketing and good communication skills,she managed to access the market easily and obtain information from experts as required.

Strategic choices have been made to spread risk. Farming is carried out using differenttechnologies, e.g. open field with drip irrigation, net house with drip irrigation and covered areawith hydroponics. Risk is further spread through growing different type of crops.

With the feasibility and viability firmly established in Tables 1 to 3, table 4 gives the dynamicdevelopment of income and cost during the first three years of operation. The cash flow analysisshows how much financing is required, which is P511,000. The graphs visualize this businessdevelopment for the first year and the first 3 years. Finally, Table 5 gives the profitability forecastand balance for the business.

ROI

There appears sufficient potential for vegatable gardening using drip irrigation. The

business is scalable to a certain degree. When more energy is required due to an

increase of cultivated land area, solar panels may be added as long as the pump can

handle the increased power, provided this has been considered when purchasing the

pump. The same business model is replicable for different parts of the country.

However, pumping head is an important parameter deteriming the Wp of solar panels

required.

The demand for fresh vegetables overrides the supply in Botswana and there is a large

market for fresh vegetables. Presently fresh vegetables are imported from South

Africa, where the conditions of growing vegetables may be better, due to better climatic

and topographic conditions.

There is competition from vegetable farms that are connedted to the mains electric

grid. Also competition from imports from South Africa.

Mains electricity (subsidized) and diesel/petrol pumping.

The water requirement matches the availability of solar energy. In Botswana irrigation is

required almost throughout the year since rainfall is erratic. There is a limitation to the

quantity and head that a solar pump is able to handle.

Pumping with grid electricity and diesel/petrol pump is on demand and therefore less

storage of water is required.

Compared to diesel/petrol pump easier to operate since operation is automatic and no

need for hauling fuel.

Due to the high cost of the solar panels the ROI

is less compared to using grid electricity for

farming of vegetables is very profitable.

Business Proposal Barber Shop

Business Description Barber Shop Proponent Mr. Onalenna Ramontshonyana has seven years experience as the owner of the barber shop. He has 3 employees that work on a part-time basis. The shop is registered with the Gaborone Town Council. Mr. Ramontshonyana has accounts with BBS and BSB and has secondary education up to form 2. Location The barber shop is located at the corner of the Kagiso Mall parking lot, opposite the private hospital, in the centre of Gaborone. Although the barber shop is located in Gaborone, there is no mains electrical connection.

Business Factors The barber shop renders barber services such as cutting of hair and shaving. The business is strategically located with high exposure to people shopping at the Kagiso Mall and people visiting the private hospital. The barber shop is housed in a portocabin which the owner obtained on a cash basis in 1999. This portocabin was paid from savings. The barber shop initially used a small generator for powering the business but it was found that the generator had high running costs and was constantly breaking down. In 2000 a solar system was purchased for approximately P5000, consisting of two 50Wp solar panels and one 100Ah batteries and a regulator and inverter. In 2006 the solar panels were stolen since they were not fixed properly on the roof. After this a portable solar panel was used that was placed outside during daytime and taken inside during the night to prevent theft. In December 2006 a new system was installed with four solar panels and four 100Ah batteries. This system is capable of providing sufficient energy for the barber shop, as well as lighting advertising located at the outside of the barber shop. The business is open 7 days per week from 8am to 19.00am There is a good opportunity to generate additional income from payphone operation and cell phone charging. Also the service may be increased by installing ceiling fans to make it more comfortable for the clients. Pre-Assessment The barber shop is an existing and operating business. It has proven to be feasible. This exercise serves as an assessment to determine if similar barber shops may be feasible in other areas and to determine what the most important success and failure factors may be. From the operational experience, the following facts are known: Cost of: Portocabin: P20.000 Inventory: P5.000 solar system: P8.000

2

Production: Number of hair cuts per day: 5/day start of the month, 20/day towards the end of the month Price per haircut: plain P15/cut style P20/cut Number of shaving per month is 50 at P5/shaving

Operational expenses: The owner has 2 to 3 helpers who are paid depending on the number of clients that they serve. It is not

clear how much these helpers earn. They are well known / relatives of the business owner. There is no payment for rent since the portocabin is owned by the entrepreneur. The portocabin is not

insured. Advertising is by word of mouth Approximately P200 is spent on shaving cream, powders, creams, etc. on a monthly basis.

The pre-assessment table1 contains all above data. Then sensitivity analysis with table 1 shows the impact of the various cost factors. Most sensitive elements are the number of haircuts per month, the price per haircut and the wages. Market Assessment There seems sufficient demand for the services that the barber shop is offering since the business has been in operation for over 7 years. Income could increase considerably if there would be more customers earlier in the month. The barber shop serves 20 persons towards the end of the month. This is four times more than in the first half of the month. A better marketing effort could improve this situation. Also there could be a price setting with a discount earlier in the month to attract more customers, to avoid working under-capacity for most of the time. Furthermore a customer loyalty programme could be established where a customer gets a free haircut say every 5th haircut. The existing barber shop is not a typical shop that is normally found in rural villages in Botswana. Most often barber shops operate either from private premises or are set up under a tree with an additional shade. An assessment has also been made for this type of operation and the results are shown in table 2. This operation is further assessed (simple barber shop). Table 3 shows a comparison between the simple barber shop that uses solar energy and a barber shop that uses hand clippers. The comparison shows that the barber shop with hand clippers has less investment cost but also fewer clients due to slower operation of the hand clippers, and as a result fewer clients can be served. Since there is a high sensitivity towards number of clients, this barber shop is not viable. It appears that the investment in a solar powered clipper pays off. Operational Plan It appears that awareness regarding the possibility of using a solar powered hair clipper is lacking with many small barber entrepreneurs. There are a number of entrepreneurs that use a car battery that they charge every number of days. Also there are no 12VDC clippers available in Botswana. What is required is a product package that offers a 12VDC clipper with one or two 12VDC lights, two 50Wp solar panels and two 100Ah batteries that can be offered to the potential users. Therefor what is required is: awareness creation technology package

Table 4 gives the cash flow during the first three years of operation. The cash flow analysis at the bottom of the table indicates clearly, how much financing would be required. Under the prevalent conditions, capital infusion of 1000 Euro would be sufficient. The graphs 4a and 4b visualize this business development for the first year, and for three years, respectively. Table 5 finally, gives the profitability forecast and balance for the business start-up.

There appears sufficient potential for Barber Shops. The business is scalable to a certain degree. When more energy is required due to an increase of customers, solar panels and batteries may be added, provided this has been considered when purchasing the regulator and inverter. The same business model is replicable for different parts of the country.

Market needs barbers and with the correct service and price setting there appears little risk

There in competition with barbers that use either clippers opereted from the electric grid, where grid connections are available and hand clippers.

Electricity (subsidized) and human operated hair clippers

Using solar powered clippers compared to hand clippers give better end result and increased speed. Solar system may power light for extended business hours and ventalation for improved comfort.

Barbers with hand clippers may operate cheaper

Better end result, faster, more comfort due to ventilationn.a.

ROI of alternative barber shop with manual hair clippers is negative due to less customers and reduced price per hair cut. Because of the high sensitivity to these to factors there is a large change in the ROI comparing the two different businesses.

Solar Water Heater for Tourist Lodge Business Proposal

Business DescriptionSolar Water Heater (SWH) for tourist lodge

ProponentThe Khutse Kalahari Lodge has been in operation since 2003. The Lodge is run by a managerat location. It is also assisted by business partners located in Gaborone and overseas.

LocationThe Khutse Kalahari Lodge is situated 10 km from the eastern gate of the Khutse GameReserve, 220 kms north-west of Gaborone, and is the final frontier before one enters therenowned Central Kalahari Desert and Central Kalahari Game Reserve.

Business FactorsThe Khutse Kalahari Lodge is strategically located outside the Khutse Game Reserve. The lodgeconsists of 12 individual guest houses with double bed, toilet and shower, and a common areawith office, bar, kitchen, restaurant and conference facilities. There are supporting buildings suchas laundry, workshop and staff houses.

Although the solar water heater systems have only been in operation for less than 4 years, aninvestment decision has to be made to replace the SWH systems or, alternatively use the dieselgenerator for heating water.

A diesel generator with engine provides power for large loads and simultaneously chargesbatteries that power smaller loads when the generator is not running. Three groups of solar waterheaters take care of the hot water requirement of the lodge.

Description of the SWH system

The lodge uses Solar Touch solar water heaters with electrical back-up elements for waterheating. Each unit has a capacity of 300 litres and is supplied by 3 solar panels. In total there are10 units (3 groups of 3 units and 1 single unit). Water is circulated by means of polypropyleneunderground pipes.

Some of the units areleaking due to frostdamage and are inneed of resoldering. Itappears that the unitsare direct systems,without heatexchangers. Warmwater production hasdecreased over timedue to extensive scalingof the units since thewater conditions in theKhutse area areunfavorable for directSWH systems.

Pre-AssessmentCalculations are based on the collector areapresently installed. The price of the SWHincluding installation at the lodge is estimatedto be P3,500/m2. The average solar radiationis estimated to be 5 kWh/m² per day. TotalSWH system efficiency is taken as 40%. Thevariable with the highest uncertainty is thespecific diesel consumption which is definedas the diesel consumption of the generatorwith engine per kWh of electricity generated.This value is estimated as 0.25 litre/kWh.An overview of values that are used in the pre-assessment are given in the table on the right.

The pre-assessment Table1 on page 4below contains all above data.Calculations were repeated for gridelectricity instead of electricity generated bya diesel engine. The calculations are basedon data from the table on the right.Results of this assessment are shown inTable 2 on page 5 below.

The table above left shows a comparison between the two sources of energy. From this Table, itcan be observed that it makes economic sense for Khutse Kalahari Lodge to repair or replacethe SWH systems since the payback period is less than 4 years. However, for a lodge that isconnected to the electric grid, it is not financially beneficial to use SWH, presuming that theassumptions that are made here are correct.

Fresh Fruit Juice Business Proposal

Business DescriptionFresh fruit juice business

ProponentArnold Tshwaranang Moleofi is a young motivated entrepreneur who is interested in running afresh fruit juice business. He has done a Business Studies course and has started a Car Washfinanced through own resources, which is run by family members. He does not have a bankaccount but is considering opening one. Mr Moleofi has no experience with formal loans but iswell acquainted with cost calculations and marketing since this was part of his professionaltraining.

LocationThe fresh fruit juice business is mobile and can be located at shopping malls, bus ranks, trainstations, public and sporting events and other locations where there is a likely market for sellingfresh fruit juice.

Business FactorsIn Botswana there are a great number of street hawkers operational, which are informalbusinesses selling a range of goods from sunglasses, hot lunches, soft drinks to ice cream.However, fresh fruit juice can only be obtained in up-market restaurants. A hawker’s license isrequired to operate in public places, which can be obtained from City and Town Councils.

The proposed fresh fruit juice business will sell a rangeof juices and non-alcoholic cocktails that are preparedon the spot using an electric juicer or blender. Bottledwater, lime, milk or cream can be added depending ontaste.

Cooling of the drink is achieved by adding ice cubes orshaved ice from a cooler box. There is no provision forelectrical cooling. Also, ice cream is not sold sincethere is already a lot of competition for this product.

The mobile unit will be similar asshown in the pictures. Theelectric juicer operates from abattery and inverter that arelocated at the bottom of thecontainer. There will be a 10Wlight provided so that the unitalso can operate in the evening.The battery is charged through a50Wp solar panel. In thecontainer is also a 20 litre waterbottle with a small pumpproviding clean water.Fresh fruits, disposable cups,straws, ingredients and a coolerbox are also stored in the unit.

Pre-AssessmentThe general feasibility of the business idea is established in a pre-feasibility assessment. Anestimation is given of business requirements and costs.

Equipment:� Inventory: P1,600 Stall on wheels, chair, umbrella, stand, water containers,

wash basin, radio with loudspeaker� Equipment: P500 Juicer, small pump� Solar system: P3,200 50Wp solar panel, battery, regulator, inverter� Advertising: P1,200 Advertising displays, price list, business cards

Total equipment cost is P6,500. Furthermore disposable items such as cups, drinking straws, etcare required during production.

Production:A quick estimation of the required production is based on the following parameters.

The highlighted parameters are variables. The expense per glass is an estimate. Based on theabove figures, the operator has to sell 64 glasses of fresh juice per day (300 days per year) tocover expenses and pay back the investment.

Operational expenses:� Disposables that are accounted for in the unit cost.� Storage space is rented for the equipment. Estimated costs P50/month.� The salary of the operator is P1000/month.

Investment live span is taken as 5 years. The solar panels have an estimated life span of 20years but there is a risk that they may get stolen.Table1 (pre-assessment) contains all above data. Sensitivity analysis with Table 1 shows theimpact of the various cost factors. Most sensitive elements are price per unit and cost per unit. Asensitivity analysis has been carried out using the goal seek function in excel. When selling 65glasses of fresh fruit per day, the payback period is 1 year with ROI of 80%, whereas selling 87glasses per day gives a payback period of ½ year and ROI of 180%. It can be concluded that theproposed business has the potential of being profitable.

Market AssessmentThere are currently no mobile fresh fruit juice vendors operating in the country. The only placeswhere fresh fruit juice may be obtained are up-market restaurants. It is believed that with theincreased awareness of fitness and health there is a market for fresh juice.

Operator income 1,000 P/month

Payback 600 P/month

Income to be generated 1,600 P/month

Days working per month 25 days/month

Profit to be made per day 64 P/day

Selling price per glass 4 P/glass

Expense per glass 3 P/glass

Profit per glass 1 P

Glasses of juice per day to sell 64 glasses/day

Fresh fruits can be obtained from a number of supermarket outlets such as Fruit and Veg City,Payless, Choppies, and others. When purchased fresh, fruits will hold for a number of days.Table 2 shows a comparison between the fresh fruit juice business using a RE system and thesame business recharging the battery from grid electricity through a commercial operator. Thecost of charging the battery, including transportation is estimated at P10 per charge. Thecomparison shows that it is more cost effective to charge the battery with solar energy.

Operational PlanThe business strategy relies on the special appeal of fresh fruit consumption to the customers, asa healthy product. It is important to generate a brand for the fresh fruit business. The businessshould be run in a professional manner in order to succeed. The operator should wear a uniformand cleanliness of the stall and personal hygiene would be critical.

Table 3 gives the cash flow during the first three years of operation. The cash flow analysisindicates clearly, how much financing would be required. Under the prevalent conditions, capitalinfusion of P6500 would be sufficient. The graphs visualize this business development for thefirst year, and for three years, respectively.

Finally, Table 4 gives the profitability forecast and balance for the business start-up.

From the Sensitivity Analysis below it becomes clear that he selling cost of a glass of juice aswell as the variable cost -being the cost of ingredients- are two critical success/failure factors.Since the maximum selling price is determined by competing soft drinks, it is of essence tocontrol the costs of the ingredients to make the business a success.

Fresh Fruit Juice Stall using PV Solar Electricity

Presently there are no mobile fresh fruit juice vendors operating. The only places where

fresh fruit juice may be obtained are up-market restaurants. It is believed that with the

increased awareness of fitness and health there is a market for fresh juice. Probably

little to no market available in villages. The same business model is replicable for

different parts of the country.

The idea of buying a fresh and healthy drink may not catch on. Many people see a can

still as a fashionable drink.

See above

Charging the battery with grid electricity. Hand press for orange juice.

Using RE a radio can be operated attracking customers and light, so that working

hours are extended.

Using RE creates a business opportunity that previously did not exist.

Fresh fruit juice is healthier and more tasteful than juice from cans.

Battery needs recycling but thsi also applies to system that does not use RE
