The 2024 rooftop-solar rules changed the economic logic
Indonesia’s Ministry of Energy and Mineral Resources issued Regulation No. 2 of 2024 for rooftop PV connected to public electricity-supply networks. The rule removed the previous 100%-of-connected-power capacity cap but introduced quota availability by PLN cluster. It also removed the former export-import crediting mechanism: excess electricity exported to the network is not credited against the customer’s bill under the new framework.
For many households, maximizing daytime self-consumption can be more valuable than designing a system around large midday export. Batteries may shift some solar energy into evening use, but their cost and efficiency must be part of the calculation.
Application and quota
ESDM states that rooftop-PV capacity is governed by available quota, with capacity allocated by utility cluster and applications handled under a first-in-first-served mechanism. Buyers should verify current quota and application procedures with PLN or the relevant IUPTLU holder before assuming a planned system can be interconnected.
Residential versus commercial load shape
Residential demand often rises in the evening, after PV production falls. Offices, retail, manufacturing and other daytime-load businesses may naturally consume a larger share of PV production as it is generated. That difference can materially change simple payback.
Current market context
Indonesia’s EBTKE dashboard reported 916.99 MW of rooftop-solar capacity as of April 2026. Capacity figures are evolving, so Melnti treats this as a dated market snapshot rather than a permanent statistic.
