Abstract

Indonesia replaced net metering for rooftop solar photovoltaics (PV) in January 2024 with a regime in which exported energy earns nothing and new connections are rationed by a five-year quota proposed by the utility. This policy analysis reads the ministerial regulations of 2018, 2021 and 2024 at article level and sets them against official capacity figures, the 2025–2034 electricity supply plan, the 2025 National Energy Policy and published engineering and techno-economic studies. Rooftop capacity rose from 140 MW (December 2023) to 538 MWp (July 2025) and 895 MW (April 2026), about 60% of all installed solar, while the 2024–2028 quota totals 5,746 MW. Installations since 2023 equal at most 40% of the 2024–2025 quota; filling the quota by 2028 would need about 156 MW per month, roughly four times the recent pace. Without export credit, a system that self-consumes half its output takes twice as long to pay back. The article argues that the quota can deliver the reduced 2 GW goal through industrial self-consumption, but not the household segment or the larger solar ambitions, because it is a ceiling without a floor set by an interested party. Feeder-level hosting-capacity quotas, inverter requirements and storage-linked export credit are proposed.
