Solar Lamp Challenge, D-Prize will award up to $20,000 per company

D-Prize is a social business competition that awards up to $20,000 of pilot funding to bold social entrepreneurs solving distribution problems in the developing world. This year we are challenging applicants to design a social venture that distributes pico solar lamps to off-grid customers. They also consider funding existing organizations if these are piloting new distribution-focused initiatives and need high risk capital. 

Almost 600 million people in sub-Saharan Africa light their homes using kerosene lamps. This has enormous poverty implications. Kerosene is dim, costs a minimum of $35 per year to keep fueled, pollutes indoor air, creates health problems, and causes fires. Fortunately, there is a proven solution. Pico solar lamps provide up to 20 times more illumination than kerosene lamps and are inexpensive, with some costing as little as $3 per unit.

Can you design a new venture to distribute pico solar lamps to customers in need? Apply to the D-Prize Global Competition for up to $20,000 of pilot funding to support your launch. The regular deadline is November 8th. To learn more, and begin your application, visit
