The recent proposal from the Kerala State Electricity Regulatory Commission to limit net metering for rooftop solar systems up to 3 kW is likely to slow down the rooftop solar installations in the state. According to the draft regulations, net metering will only be permitted for rooftop solar systems with a capacity between 3 kW and 5 kW, provided they include energy storage systems (ESS) that account for up to 30% of the rooftop solar capacity. The Commission proposed limits on net metering and a mandate for ESS for rooftop solar projects in its draft order titled ‘Renewable Energy and Related Matters Regulations, 2025.’
