6 FAQs about [Stratified storage of solar energy Madagascar]

Is Madagascar ready for solar power?

What is Scaling Solar in Madagascar?

Madagascar is currently the fifth country in Africa in which a Scaling Solar tender process was launched, after two tender processes in Zambia, one in Senegal, and another in Ethiopia. It is also the first Scaling Solar project to include solar energy storage requirements by pairing solar with batteries.
