New Delhi: India added 1.2 GW of rooftop solar capacity in the January-March quarter of 2025, marking a 232 per cent increase over the 366.5 MW installed in the corresponding quarter of 2024, according to Mercom India Research.
The installations in Q1 2025 were 6 per cent lower than the 1.3 GW added in Q4 2024. The capacity addition during the quarter was the second-highest ever for rooftop solar installations in the country.
According to Mercom, the PM Surya Ghar: Muft Bijli Yojana contributed to more than 77 per cent of the installations in the quarter. However, the quarter fell short of a new record due to implementation bottlenecks in the programme, high system costs, and a shortage of Domestic Content Requirement (DCR) compliant modules.
The residential segment accounted for nearly 78 per cent of rooftop installations in the quarter. The industrial, commercial and government segments accounted for 16 per cent, 6 per cent, and 0.4 per cent, respectively.
Installations under the capital expenditure (CAPEX) model comprised over 91 per cent of the additions, while the operational expenditure (OPEX/RESCO) model accounted for 9 per cent.
"Momentum in the
residential solar segment
has slowed due to implementation hurdles in the Surya Ghar program, persistent component shortages, and high system costs. Consumer expectations are not being met, whether it is cost, quality, or installation timelines. Addressing these issues is critical to unlocking the true potential of the residential solar market," said Raj Prabhu, CEO of Mercom Capital Group.
Among states, Gujarat, Maharashtra and Uttar Pradesh led in rooftop solar capacity additions, accounting for over 16 per cent, 14 per cent, and 13 per cent, respectively.
Tenders for rooftop solar totalling 494.2 MW were issued in Q1 2025, representing a decline of over 53 per cent quarter-on-quarter and 41 per cent year-on-year. Of this, 82 per cent of the tendered capacity was for government buildings, and 39 per cent of it fell under the PM Surya Ghar programme.
At the end of Q1 2025, India's cumulative rooftop solar capacity stood at 14.9 GW. The rooftop segment accounted for over 18 per cent of the total solar installations in the quarter.
Uttar Pradesh recorded the highest compounded quarterly growth rate between Q1 2024 and Q1 2025 at more than 15 per cent, followed by Madhya Pradesh and Kerala at 11 per cent and 9 per cent, respectively.
The average cost of rooftop solar systems rose by about 1 per cent quarter-on-quarter and nearly 22 per cent year-on-year in Q1 2025.
