India’s solar industry is entering a new, more mature growth phase, driven by rapid rooftop adoption and rising customer expectations, Shweta Solar Pvt. Ltd. says. The country’s total installed solar photovoltaic (PV) capacity has now surpassed 140 GW, reflecting steady expansion backed by strong policy support, efficient execution and growing investor confidence. This milestone marks India’s position among the world’s major solar markets.
According to Sanjay Garg, Director of Shweta Solar, “With installed capacity crossing 140 GW and rooftop adoption accelerating, the market is maturing. Customers are thinking long term. They want systems that perform consistently year after year, irrespective of geography…”
Demand Trends and Rooftop Growth
Growth in 2025 was significant, with nearly 44.5 GW of new capacity added to the grid, most of which was solar. While utility‑scale ground‑mounted projects continue to lead capacity additions, rooftop installations made a notable impact, contributing nearly 7 GW.
In the first nine months of 2025, 4.9 GW of rooftop solar was installed, which is about 161% more than the same time the year before. By early 2026, the total capacity of rooftops was close to 18.6 GW. Demand was growing from smaller cities and semi-urban areas, as well as homes and businesses.
Shifting Buyer Priorities and Policy Support
Shweta Solar notes that conversations with buyers are shifting beyond upfront pricing to focus on long‑term performance, durability and system reliability under Indian climatic conditions. Factors such as extreme heat, humidity or coastal salinity are influencing purchasing decisions.
Government programs like the PM Surya Ghar Muft Bijli Yojana have made it easier for people to get on roofs, and the fact that prices for solar panels have gone down while prices for grid power have gone up has made solar a good financial choice for many people.
Policy backing remains strong. The Union Budget 2026–27 allocated more than ₹30,500 crore to solar programmes, an increase from the previous year, supporting both large projects and decentralised installations.
Looking Ahead: Performance and Reliability
Solar electricity generation also surged in 2025, rising by about 22 % as more commissioned projects began operating at full capacity.
Mr. Garg added, “The next stage of growth will reward consistency. Performance, process discipline and field‑tested reliability will define how effectively companies contribute to India’s clean energy ambitions…”
As India pursues its 500 GW non‑fossil energy target by 2030, industry focus is gradually shifting from capacity expansion to long‑term performance and system durability factors that may define the solar sector’s next growth chapter.
