Solutions · Three Paths
Three solar segments for Indonesia — each with a dedicated calculator, cited primary data sources, and output matched to your decision context.
Rooftop home solar, 1–10 kWp
Calculate optimal capacity from your monthly PLN bill. Default tariff R-1 1300 VA non-subsidized, with a toggle for pre/post-Permen ESDM 2/2024 net-metering scenarios.
Mid-scale capacity, 50 kWp – 5 MWp
Discounted NPV/IRR/payback modeling with the Permen ESDM 2/2024 tax allowance. Compare self-build vs PPA vs BOO (Build-Own-Operate) schemes.
Independent of the PLN grid
Size solar + batteries for sites without grid access. Compare LCOE vs a diesel generator. Hybrid configuration (PV + battery + optional diesel backup).
