Hi Ahmed!
There are a few platforms that have at least parts of their site dedicated to projects in Africa. JustGiving is one that has a whole section dedicated to it. You’ll need to find one that will work with the type of project you’re looking to do though. Renewable energy materials are pretty niche, and not very many crowdfunding sites will have the audience you need to make it a success. I would work on finding sites that play well to the project first, and make Africa the secondary qualifier in finding the right platform for you! Good luck in your crowdfunding efforts!
Best,
Jeff
