Imagine if your day ended when
the sun went down…
Works stops.
Stores close.
Your house and community have
no light other than the flicker of flame

1.1 Billion people have no electricity
Rural Africans spend 10-30% of their household
income on dirty and dangerous
kerosene lighting
People will walk 30-60 minutes a day just to charge their
phonesCredit: Craig Neville-Manning

The traditional grid is too costly for rural communities• Extending the grid in Africa
costs $7,000 to $25,000 per kilometer1
• Rwanda, one of the most advanced African economies, is expanding the grid at the slow pace of 2-3% per year – many people will wait 8-9 years2
• There is an initial connection fee of more than $1,0002
• East African utilities are subsidizing electricity costs at more than $500 million per year3

Solar LanternsIMPACT• Lanterns lower household costs
for lighting by reducing or eliminating more expensive kerosene light
• Lanterns reduce toxic fumes and fire risk of kerosene
• The number one use of solar lanterns is for children to study (nearly 100%)1
TECHNOLOGY• The average price of a lantern
has dropped from $50 in 2009 to $9 in 2017 – prices are expected to continue dropping
• Price drops are fueled by plummeting costs of solar cells, LED lights and batteries
• 30 million units sold worldwide2

Solar Home SystemsIMPACT• Phone charging eliminates
hours and hours of walking and save $1.00 - $2.00 per month in charge fees
• Radio and, increasingly, television provide education, entertainment and community
TECHNOLOGY• $100 - $250 costs add in
radios, multiple lights and phone charging
• Daily payments via mobile phones minimize upfront costs – “Pay as you go” (PAYG)
• Analytics help assess credit worthiness

Larger Solar SolutionsIMPACT• Agriculture – irrigation pumps
means year-round growing season and more valuable crops
• Refrigeration - more flexibility when food is consumed; also means storage for medicines
TECHNOLOGY• $500 - $1,000 provides
complete well pump, solar panels and drip irrigation solution
• Financing technology from SHS market is a big enabler here
• Refrigeration is another step in power and also in impact – look for this to emerge in 2018+dsa

DISCUSSION QUESTION
How should we advise a government minister from a low income region to invest their limited funds to maximize energy access?
