India Adds Over 18 GW Solar Capacity In 2026 As Total Installed Solar Base Crosses 154 GW

India’s renewable energy sector continues to witness strong growth in 2026, with solar energy leading the expansion and reinforcing the country’s clean energy ambitions. By the end of April 2026, India’s total installed solar photovoltaic capacity reached nearly 154.236 GW, making solar the largest contributor to the renewable energy sector. Solar alone now accounts for almost 67.7 percent of the country’s renewable energy capacity, excluding large hydro projects, highlighting its central role in India’s future power generation plans.

The sector has started 2026 on an exceptionally strong note. During the first four months of the year, India added around 18.426 GW of new solar capacity, reflecting one of the fastest growth phases seen in recent years. April 2026 itself recorded nearly 3.975 GW of fresh installations in a single month, indicating improved project execution, faster commissioning, and rising investor confidence in the sector. Industry experts believe that if this pace continues, 2026 could become a record-breaking year for India’s solar market.

Wind energy is also contributing steadily to India’s renewable energy transition. Total renewable energy capacity excluding large hydro has now reached around 227.59 GW, with solar and wind together accounting for more than 210 GW. This means the two technologies now represent over 92 percent of the renewable energy mix, strengthening India’s efforts to reduce dependence on fossil fuels and increase clean power generation.

Ground-mounted solar projects continue to dominate the market, with total installations surpassing 117.36 GW. Rooftop solar is also witnessing strong growth and has crossed 26.75 GW due to increasing adoption among residential consumers, commercial establishments, and industries seeking lower electricity costs and energy independence. Hybrid renewable projects combining solar and wind capacity have reached around 3.96 GW, while off-grid solar installations have crossed 6.17 GW, helping improve electricity access in rural and remote regions.

Government initiatives continue to support this momentum. Policies such as the Production Linked Incentive scheme and the Approved List of Models and Manufacturers are encouraging domestic manufacturing and improving product quality. The upcoming ALMM wafer compliance requirement from 2028 is also expected to strengthen India’s local solar manufacturing ecosystem and reduce reliance on imports.

At the same time, improving global market conditions are offering relief to developers. Reduced geopolitical tensions in the Middle East are helping stabilize supply chains, freight rates, and shipping costs. However, challenges related to land acquisition, transmission infrastructure, and supply chain risks still remain. Despite these hurdles, rising power demand, supportive policies, and growing investments indicate that India’s renewable energy sector is likely to maintain strong and sustained growth in the coming years.
