We understand that Indonesia’s solar energy is often given the term “massive, but untapped”. But how massive is massive?

We decided to calculate technical potential for residential buildings in 34 provinces in Indonesia, taking into account statistics data, suitable roof area, access factors, and power density. We used method utilized by global experts and made some assumptions when needed.

We found out that residential rooftop solar technical potential in Indonesia amounts to 194 – 655 GWp. And by considering homeowners assumed to have financial capacity to install rooftop solar, 17.8% of the potential can be regarded as feasible to achieve, marketwise.
