Delhi’s rooftops are slowly becoming power stations. From homes in Rohini and Dwarka to schools, factories, hospitals, malls, offices, warehouses, and housing societies, solar energy is no longer a rare idea in the capital. It has become a practical way to cut electricity bills, reduce dependence on grid power, and move towards cleaner energy.
In 2026, Delhi’s solar market is growing because of rooftop solar demand, government subsidy schemes, net metering, commercial solar adoption, and rising awareness among residential consumers. Recent reports say Delhi has crossed more than 24,000 rooftop solar systems, contributing around 420 MWp to the city’s power grid. This shows that solar is no longer just a future plan for Delhi; it is already becoming part of daily electricity use.
