General on Renewable Energy

• Renewable energy is goodfor the environment as youlimit your Co2 output– PV, Wind, Hydro– Often mixed with storage

systems

• When matched againstgenerators, Hybrid systems with PV and storage is alsothe cheapest solution if calculated right.


General on Renewable Energy

• When focus is on renewable energy it oftenalso generates focus on the actualconsumption and the limitation thereof.

• There is a renewable energy system for everypurpose. If you can define it properly you canimprove the overall TCO – even with backup generator.


System Calculations

• A battery driven energysystem is best designed to meet a defined load and energy profile.

• Inaccurate profile can makethe system

– Fail

– Unnecessarily expensiveBenghazi Pediatric Hospital, Libya


System Calculations

3 main factors:

• Power

– How much power (kW) is required to ensure the operation of all loads

• Energy

– How much energy (kWh) is required during a certainperiod – typically 24h

• Storage

– For how long time is it required for the system to operatewithout the need for external power sources


System Calculations

• Once the 3 main factors have been determined, you consider otherimportant system criteria– AC or DC Coupling

– Interaction with one or more external energysources

– Future expansion options

– Local conditions• Temperature

• Roof / Open space


Power

The amount of power needed is what is at maximum required to operate all load connected to the system.

Energy

The energy requirement is important to calculate the size of the PV plant.

Sometimes it is possible to measure the consumption and sometimes youhave to make a list of connected items and calculate the energy

Energy

The used Solar irridation is a standard UN for worstproduction period. To get the proper value, you look at the total system and use a professional calculationprogram.

Storage

Stored energy is used at time when PV and/or the external energy source is not available.

The tendencies is to consider:

- Nighttime only (Silent night)

- A few hours because grid is generally stable or a generator is automaticallystarting

- Several days (Vaccine or remote areas)

Storage TypeBattery Technologies:• AGM, GEL, Longlife 2V OPzV, 2V OPzS and LiOn batteries.

• AGM and GEL is used for small applications of no more than 15 kWh per day.

• 2V OPzV and 2V OPzS are designed for higher currents and in particular solar installations.

• Lithium is used primarily in applications with focus on low weight (mobile systems), limited space (Containers), UPS or where the client want the best TCO.

Calculation sum up

• Know your power requirement (calculation or measure)– Look for the maximum simultaneous load

• Example: 6000W max load

• Know your energy requirement for a 24h period (calculationor measure). – Divide the found by 2,5-4 depending on local circumstance to get your

PV plant size in kWp• Example: Consumption is 60.000W

– PV requirement is minimum 60kW/4 = 15kWp (not regarding seasonal changes)

• Know your required storage in kW.– Divide the found by discharge level and efficiency (eg 0,5 and 0,9) to

get your storage.• Example: Night consumption is 20.000Wh

– Storage is 20kWh /(0,5 x 0,9) = 45 kWh.


Professional Calculations


Do’s and Dont’s

• Do’s:

– Make correct system calculations to increase the quality of your delivered and installed system.

– Instruct users that loweringconsumption significantlyimproves the system performance and TCO.

• Dont’s:

– Purchase a PV-Hybrid system as if it is a generator.• The energy that a generator

have 24 hours to generate, a PV system need to generate when daytime (or as in earlierexample, during 2,5-4 hours)

– Suddenly think that havingenergy means free access to energy. The system is designed for a purpose.
