Government of Indonesia has set the target for solar deployment at 6.5 GW cumulative installed capacity of solar by 2025. General Planning for National Energy regulated the mandatory use of rooftop solar for public buildings (a minimum of 30% of roof area), but this has yet to be executed effectively.

Government should act as “early adopters”, play a major role in bulk procurement of rooftop solar and thus grow the market size.
