Five ways to finance rooftop solar

Most homes in Punjab do not pay for solar in one go. There are five common ways to spread the cost, and they differ in what they are secured against, how quickly they come through, and whether they suit a system claiming the subsidy.

Before choosing a loan, know the size and the price. Our solar calculator gives both from your bill, and the price after subsidy, which is roughly what you will need to fund once the subsidy comes back.

The five routes, side by side

The PM Surya Ghar bank loan

The scheme has its own loan, through public-sector banks. The government’s release of March 2025 gave the rate as a subsidised 6.75% on collateral-free loans up to ₹2 lakh, through 12 banks, with the application online. For a home system claiming the subsidy it is usually the first place to look. More on the PM Surya Ghar loan.

A top-up on your home loan

If you already have a home loan, many banks will lend more on top of it, secured against the same house. Because it is secured, a top-up is usually cheaper than an unsecured loan and can run longer. It needs a home loan in good standing. More on the home loan top-up.

A personal loan

Unsecured, so nothing is pledged, and often the quickest to arrange. The trade is cost: personal loans usually carry a higher rate than secured borrowing, over a shorter term. It suits a smaller system or a gap between the price and your savings. More on the personal loan.

An NBFC

Non-banking finance companies are lenders registered with the Reserve Bank of India that are not banks. Some lend specifically for solar, and they can be quicker or more flexible on eligibility, often at a higher rate than a bank. More on NBFC solar loans.

If you would rather not find a lender yourself, we can put you in touch with our finance partner when we quote. The financier makes its own credit decision on its own terms; we cannot promise approval or a rate. Ask us on WhatsApp for the current terms.

Whatever you choose

  • The loan and the subsidy are separate. The PM Surya Ghar subsidy is paid into your own bank account after the DISCOM inspection, never to a lender, and it does not reduce what you owe.
  • Compare the full cost of each loan: the rate, any processing fee, the term, and what happens if you repay early.
  • Decide the system first, then the loan. Our guide to financing a rooftop system covers what to check before signing.
