solar power is nice on a household and retail level. but let's be frank solar will not power industrial machinery needed to change africa's fortunes. hydrocarbons are cheap. solar yeah can be free but the capital needed to say a 1MW solar plant is about 350K USD while a 1 MW generator can be from 25k USD to 200K depending on manufacturer, type of fuel etc. Plus the generator can run all night.
