Mawuli Tse has already brought solar power to hundreds of residents in urban Ghana and other African countries.
Now thanks to a $100,000 grant, he's creating a solar product for street vendors in rural areas, reports Jamie McGee of the Tennessean.

Vendors may also use the system for light, allowing them to stay open later or for use at homes, Tse said.
