Rooftop Solar Growth, PM Surya Ghar & New Industry Updates

Solar News Today in India – 17 September 2026

India's solar energy sector continues to see significant activity across residential rooftop solar, manufacturing, energy storage and renewable-energy policy. Today's developments show continued growth in solar adoption while also highlighting challenges in the domestic solar supply chain.

1. India's Rooftop Solar Market Could Reach 132 GW Potential

The Indian Solar Manufacturers Association (ISMA) has estimated that India's residential rooftop solar market has an overall potential of around 132 GW. According to the latest industry outlook, annual residential rooftop installations could reach around 9 GW to 15 GW between 2026 and 2030.

The report identifies the PM Surya Ghar: Muft Bijli Yojana as an important driver of residential rooftop solar demand. The opportunity also creates potential demand for solar modules, cells, inverters and other balance-of-system equipment.

For solar dealers and installers, the expected growth in residential rooftop installations could increase demand for customer acquisition, site surveys, quotations, financing assistance and installation services.

2. PM Surya Ghar Continues to Drive Rooftop Solar Adoption

The PM Surya Ghar: Muft Bijli Yojana remains one of the major government programmes supporting residential rooftop solar adoption in India. Recent reporting indicates that the scheme is continuing to expand, with the government targeting a large number of participating households.

According to a recent statement reported by Moneycontrol, the Ministry of New and Renewable Energy expects the scheme to cover approximately 85–90 lakh households by March 2027, compared with the original one-crore household target.

Customers should always verify the latest eligibility, subsidy and application requirements through official government portals before making a solar purchase.

3. Current Residential Solar Subsidy Information

Government portals currently provide information on central financial assistance for eligible residential rooftop solar installations. The Delhi Solar Portal, updated on 17 September 2026, lists central subsidy rates of ₹30,000 per kW for the first 2 kW and ₹18,000 per kW for additional capacity up to 3 kW, with the total subsidy capped at ₹78,000 for systems above 3 kW.

Subsidy eligibility and implementation can depend on the applicable scheme guidelines, consumer category, DISCOM process and other conditions. Customers should check the latest official information before applying.

4. Solar Manufacturing Faces Module and Cell Supply Mismatch

India's solar manufacturing industry is also experiencing a supply-chain imbalance. A September 17 report from Mercom India highlights a mismatch between domestic solar module manufacturing capacity and cell production capacity.

The report says average module manufacturing capacity utilisation has been around 35% to 40%, with module capacity expanding faster than domestic cell production. This illustrates the importance of balancing manufacturing capacity across different stages of the solar supply chain.

5. Battery Storage Becomes Increasingly Important

As renewable generation grows, energy storage is becoming an increasingly important part of India's power-sector planning. Battery Energy Storage Systems can help manage variations in renewable generation and support electricity supply when solar generation is unavailable.

Recent industry updates also indicate increasing attention toward expanding storage capacity and improving the integration of renewable energy into the electricity grid.

6. New Solar Technology and Manufacturing Developments

Solar technology continues to develop beyond conventional crystalline silicon modules. Mercom India reported today that GREW Solar and Caelux have entered into a five-year commercialisation agreement involving perovskite technology, with plans associated with up to 4 GW of module production.

Perovskite-based technologies are being researched for higher efficiency and new solar applications. Commercial deployment will depend on manufacturing scale, reliability, cost and long-term performance.

7. What Today's Solar News Means for Customers

• Residential rooftop solar remains a major growth area.
• Government-supported programmes continue to influence household adoption.
• Customers should verify the latest subsidy information before installation.
• Solar financing can help customers manage upfront project costs.
• Energy storage is becoming increasingly important alongside solar generation.
• Solar manufacturers are working through changing domestic supply-chain conditions.
• New technologies may create additional opportunities in the future.

8. What Solar Dealers Should Watch

Solar dealers and installers should closely follow government notifications, DISCOM procedures, subsidy rules, module and inverter requirements, financing options and changes in solar technology.

For B2C solar sales, accurate quotations and transparent communication are particularly important. Dealers should clearly explain system capacity, equipment, installation charges, applicable taxes, financing terms and subsidy conditions.

Official Government Information

For the latest government notifications and renewable-energy updates, customers and solar professionals should refer to the Ministry of New and Renewable Energy (MNRE) and the official PM Surya Ghar portal.
