SolarAid are managing the first large-scale randomised control trial study into the impact of solar lights on poverty alleviation and pollution/health outcomes. The study, funded by Google, is being conducted in Kenya, and results are expected in 2016. The pilot study was completed at the end of last year; the main study design is now being finalised. The research is being carried out by ETH Zurich, the Swiss Federal Institute of Technology. The add-on pilot study into exposure to pollution is being delivered by researchers at the University of California, Berkeley alongside ETH Zurich. SolarAid’s Director of Research & Impact, Kat Harrison, is managing the project with an aim to make the results available and of use to the whole sector to provide evidence to enable engagement with governments, policy-makers, donors and practitioners of the importance of solar lights for development. A dedicated webpage has been set up to host updates on the process and findings throughout the two years and you can get news through Kat’s blog or by following her on Twitter.
