Xia Li is Founder of Shenzhen Power-Solution, a Chinese supplier of off-grid solar home systems designed for the 730 million people worldwide who lack access to electricity and rely on candles and kerosene for lighting. To date, her company has provided solar-powered light to nearly 50 million people in more than 7 million households, with a heavy focus on sub-Saharan Africa. In the process, it has protected tens of thousands of children from respiratory diseases caused by using kerosene and candles. She was inspired to bring solar lighting to the poor after visiting India’s slums in 2007.
