The government expects rooftop solar installations to more than double to four million by March 2026, supported by the newly introduced utility-led aggregation model under the Prime Minister Surya Ghar Muft Bijli Yojana. This forms part of the broader target of installing 10 million rooftop solar units by March 2027, with 1.7 million households having adopted the systems so far. Officials estimate that the aggregation model could itself add around one million installations by enabling distribution companies to aggregate demand and implement rooftop solar projects on behalf of households. The model is designed to streamline approvals, improve vendor accountability, and reduce costs for consumers.
