Olivia launched Juabar in Tanzania. Juabar kiosks use solar power to charge mobile phones and are also a point-of-sale for household solar lamps. Kiosks are run by local “jua-preneurs”. With support from D-Prize, Olivia will support 15 local jua-preneurs, and sell 400 solar lamps in three months; and scale to 32,000 products and 150 Juabar kiosks in two years. Ani Vallabhaneni, co-founder of Sanergy, is serving as a mentor.
