The government recently approved a power utility-led model under the PM Surya Ghar: Muft Bijli Yojana, which will rapidly increase rooftop solar installations, said Union Minister of New and Renewable Energy Pralhad Joshi. Approximately two million rooftop solar systems have been installed under the Surya Ghar program so far. Approximately half of the households were receiving zero bills, and many were also earning money by selling excess electricity. Within a month after the demand-driven utility-led model is rolled out, installations would reach five million, the minister said.
