The residential segment accounted for nearly 78% of installations in Q1 2025. The industrial, commercial, and government segments accounted for approximately 16%, 6%, and 0.4% of the total capacity added during the quarter.

Installations under the capital expenditure (CAPEX) model accounted for over 91% of the quarterly additions, and capacity additions under the operational expenditure or renewable energy service company (OPEX/RESCO) model accounted for the rest.

Gujarat, Maharashtra, and Uttar Pradesh led rooftop solar capacity additions during the quarter, accounting for more than 16%, 14%, and 13%, respectively.

The capacity added during the quarter was the second-highest quarterly installations to date. The PM Surya Ghar: Muft Bijli Yojana (PM Surya Ghar program) remained the key growth driver, contributing to over 77% of the total installations during the quarter. The quarter would have witnessed record installations if not for the implementation bottlenecks in the PM Surya Ghar program and rising costs and shortage of Domestic Content Requirement (DCR) compliant solar modules.
