New Delhi: Delhi's rooftop solar capacity has crossed 420 MW across more than 23,000 installations, with the city's distribution companies reporting rapid uptake. Assuming an average household load of 2 KW, the installed base is sufficient to meet the daily electricity needs of over two lakh households and institutions, discom officials said on Monday.

The BSES discoms — BRPL and BYPL — have energised more than 13,600 rooftop solar connections with a combined capacity of around 260 MWp (megawatt peak), a company spokesperson said. Megawatt peak measures the maximum output of intermittent sources such as solar and wind under optimal conditions.
The BSES rooftop solar base is generating annual savings of nearly Rs 200 crore for consumers, the spokesperson said. Domestic consumers account for the bulk of connections at 9,888, followed by commercial (2,184), educational (1,009), others (342) and industrial (207).
Around 4,600 rooftop solar connections were energised by BSES in FY2025-26, the highest ever in a single year. Of these, more than 2,600 were under the central government's PM Surya Ghar: Muft Bijli Yojana scheme. The total number of PM Surya Ghar connections energised by BSES discoms has now crossed 4,100, the spokesperson said.
Tata Power Delhi Distribution Limited (TPDDL), which supplies power across North Delhi, has energised over 10,000 rooftop solar installations with a total capacity of 160 MWp, a company spokesperson said. Under the PM Surya Ghar: Muft Bijli Yojana, TPDDL has energised a record 4,375 rooftop solar plants with a combined capacity of 20 MWp.

Officials attributed the sharp acceleration in rooftop adoption to combined subsidies under the PM Surya Ghar: Muft Bijli Yojana and the Delhi Solar Policy, which together amount to Rs 1.08 lakh for residential consumers. For a typical household, a 5 kW rooftop solar system can potentially deliver savings of Rs 3,500 or more per month, depending on consumption levels and tariff slab, officials said. Surplus power generated beyond a consumer's own requirement is purchased by the discoms at prices determined by the Delhi Electricity Regulatory Commission (DERC).
