The Solar Financing Boom of 2026
To support the PM Surya Ghar Yojana's ambitious target of lighting up 1 crore rooftops, the Reserve Bank of India (RBI) has strongly encouraged banks to classify solar loans under Priority Sector Lending (PSL).
This mandate has led to a massive flood of highly competitive, zero-collateral loan products entering the market.
If you are planning to install a solar plant up to 3kW (costing roughly ₹1.5 to ₹2 Lakhs), you no longer need to pledge your property or provide guarantors.
Here is our curated list of the top 5 banks dominating the solar financing space right now.
