With rural electrification in Madagascar at only three per cent, people resorted to kerosene lamps. Besides the problem of indoor air pollution, these lamps were a fire risk and emitted a lot of CO2. Bernard Hulshof designed a solar lighting system powered by a separate solar panel for social enterprise, BushProof.

His portable light ball was powered by a separate solar panel. Its lithium battery lasted some 50 hours on the lowest of the four dimmer switch settings, meaning it could be used as a nightlight to replace candles. Technological advances enabled this kind of consumer product for people in low income countries. Changing attitudes also played a role: rather than giving things for free and disrupting the market place, people should have access to products for a reasonable price. With BushProof focusing on water and sanitation, Hulshof and partner Arnoud de Vroomen set up startup SolarWorks! to continue working on solar lighting.

360° Experience:

WakaWaka’s Power + also integrates a solar light and a power pack. The global off-grid sector is already providing solar powered lighting to hundreds of millions of people, with SolarWorks! now selling solar home systems in Mozambique.
