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.
Updated 27 September 2026
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
| Route | Secured against | Best suited to |
|---|---|---|
| PM Surya Ghar bank loan | Nothing, for eligible loans up to ₹2 lakh | Home systems up to 3 kW claiming the subsidy |
| Home loan top-up | Your house, through your existing home loan | Owners with a home loan, and larger systems |
| Personal loan | Nothing | Smaller amounts, when speed matters |
| NBFC loan | Depends on the NBFC | When a bank will not lend, or quicker decisions |
| Our finance partner | The financier’s own terms | When you would rather not find a lender yourself |
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.

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.

Questions we are asked
What is the cheapest way to finance rooftop solar?
For a home system claiming the PM Surya Ghar subsidy, usually the scheme's own bank loan. The government's March 2025 figure was 6.75% through 12 public-sector banks, collateral-free, for loans up to ₹2 lakh. Banks set the current rate, so ask yours.
Does the subsidy reduce the loan?
No. The loan and the subsidy are separate. The subsidy is paid into your own bank account after the DISCOM inspection; you repay the full loan on the lender's schedule, whenever the subsidy arrives.
Does RSK Solar Energy give loans?
We are not a lender. We can connect you with our finance partner, who makes its own credit decision; we cannot promise approval or a particular rate.
