HDFC Bank does not list a dedicated retail “solar loan” on its website. Homeowners who want HDFC finance for a rooftop system use one of two secured home loan products: a top-up on an existing HDFC home loan, or a home improvement (renovation) loan. Both are priced off the RBI repo rate, and both are processed by HDFC’s home loan division.
Key takeaway. HDFC’s published rates in October 2026 are 7.75% to 13.20% p.a. for home improvement loans and 8.00% to 13.70% p.a. for top-up loans, both repo-linked. A top-up can run for up to 15 years. A ₹2 lakh loan at 9.5% over 10 years has an EMI of about ₹2,588. Heaven Green Energy can help you apply and can prepare the installer documentation for your HDFC application within 24 hours.
This guide covers HDFC’s product routes, published rates for 2026, EMI tables, eligibility criteria, the document checklist, and a step-by-step application guide.
HDFC Solar Financing Routes: Top-Up vs. Home Improvement Loan
HDFC’s home loan division offers two routes that can fund a rooftop system:
HDFC Home Loan Top-up: For customers who already have an HDFC home loan, a top-up is usually the simplest route because the property is already mortgaged and your repayment record is on file. You can apply 12 months after the final disbursement of your existing home loan, once the property is complete. The top-up is capped at your originally sanctioned home loan amount (subject to HDFC’s overall ceiling), and your total outstanding plus the top-up cannot exceed 80% of the property’s market value (75% if the total exposure is above ₹75 lakh). The maximum term is 15 years or until retirement, whichever is earlier.
HDFC Home Improvement Loan: For buyers without an HDFC home loan, the home improvement (renovation) loan is the secured route. For new customers HDFC funds up to 90% of the improvement estimate on loans up to ₹30 lakh, subject to the property’s value and your repayment capacity. Because the home is mortgaged, expect a property check and fuller documentation than a top-up.

HDFC Solar Loan Interest Rates 2026
| Product | Published rate (p.a.) | Benchmark |
|---|---|---|
| Home improvement loan | 7.75% to 13.20% | Repo rate (5.25%) + 2.50% to 7.95% |
| Home loan top-up | 8.00% to 13.70% | Repo rate (5.25%) + 2.75% to 8.45% |
Source: HDFC Bank home improvement loan and top-up loan pages, checked 2 October 2026. HDFC prices these loans as the repo rate plus a spread; your spread depends on your credit profile and loan size, so the rate moves when the RBI changes the repo rate.
The key point: the rate you are offered depends on your profile, not on the product label. Get the quoted rate in writing and compare it with SBI before you sign.
HDFC Solar Loan EMI Tables
EMI calculations at an illustrative 9.5% for various loan sizes and tenures:
| Loan Amount | 5 years | 10 years | 15 years |
|---|---|---|---|
| ₹1,00,000 | ₹2,100 | ₹1,294 | ₹1,044 |
| ₹2,00,000 | ₹4,200 | ₹2,588 | ₹2,088 |
| ₹3,00,000 | ₹6,301 | ₹3,882 | ₹3,133 |
| ₹5,00,000 | ₹10,501 | ₹6,470 | ₹5,221 |
| ₹10,00,000 | ₹21,002 | ₹12,940 | ₹10,442 |
For personalised calculations based on your exact loan amount and rate quote, use our solar calculator. The critical benchmark: your EMI should be less than or equal to your monthly electricity bill savings. For a ₹5,000 monthly electricity bill, the break-even EMI is ₹3,750–₹4,000 (assuming 75 to 80% solar offset).
HDFC Solar Loan Eligibility Criteria
Who can apply:
- Salaried individuals and self-employed professionals or business owners with a stable, documented income
- Top-up: existing HDFC home loan customers, 12 months after final disbursement and once the property is complete
- All co-owners of the property must be co-applicants
Property and security:
- You must own the property where solar is being installed
- Both routes are secured on the residential property
- For top-ups, total outstanding plus the top-up cannot exceed 80% of market value (75% above ₹75 lakh exposure)
Income criteria:
- Lenders assess repayment capacity from your income and existing EMIs. A common rule of thumb is that total EMIs, including the new one, should stay within roughly 40 to 50% of gross monthly income; HDFC sets the actual limit case by case
- Example: For a ₹5 lakh loan over 10 years at 9.5% (EMI ₹6,470), that rule of thumb implies gross monthly income of about ₹12,940 to ₹16,175 with no other EMIs
Credit profile:
- A higher credit score generally earns a lower spread over the repo rate
- Check your CIBIL report before applying, a loan application triggers a hard enquiry
- If your score is weak, see our guide to solar loans with a low CIBIL score for alternative paths

Comparing HDFC with Other Solar Lenders
For a full comparison of all major lenders, see our solar loan EMI comparison 2026, or read our dedicated guides to ICICI and Bajaj Finserv solar loans if HDFC doesn’t fit your profile. If you’re weighing a secured solar loan against an unsecured option entirely, see solar loan vs. personal loan. The quick summary:
| Factor | HDFC home loan top-up | HDFC home improvement loan |
|---|---|---|
| Published rate | 8.00% to 13.70% | 7.75% to 13.20% |
| Who it suits | Existing HDFC home loan customers | Owners without an HDFC home loan |
| Funding limit | Original sanctioned amount, within 80% of property value | Up to 90% of the estimate (new customers, loans up to ₹30 lakh) |
| Foreclosure (variable rate) | Nil | Nil |
| Processing fee (salaried) | Up to 0.50% or ₹4,000, whichever is higher | Up to 0.50% or ₹4,000, whichever is higher |
Verdict. For an existing HDFC home loan customer, a top-up is usually the simplest route. Without an HDFC home loan, compare HDFC’s home improvement loan quote with SBI and other lenders on the actual rate offered to you, not the headline range.
Common Mistakes Buyers Make with HDFC Solar Loans
-
1
Asking for a "solar loan" at a general branch, HDFC finances rooftop solar through its home loan products, so start with the home loan division.
-
2
Using a non-registered installer's quote, if you also want the PM Surya Ghar subsidy, the installer must be a registered vendor for the scheme. Always use a registered EPC like Heaven Green Energy.
-
3
Choosing a fixed rate when you plan to prepay, a fixed-rate period carries a 2% premature closure charge (unless you prepay from your own funds), while variable-rate loans carry none.
-
4
Skipping the DISCOM application step, lenders often ask for proof that the net metering application has been filed. Without it, disbursement may be delayed even after sanction.
Pros and Cons of HDFC Solar Loan
- Top-up builds on your existing home loan, so the property is already on file
- Online application with document upload
- Repo-linked rates from 7.75% p.a. (home improvement)
- Long tenure, up to 15 years on a top-up
- No dedicated solar product, so you need a mortgage-backed loan
- Wide published range (7.75% to 13.70%), your spread depends on your profile
- Processing fee of up to 0.50% or ₹4,000, whichever is higher
- Top-up only available 12 months after final home loan disbursement

Frequently Asked Questions
What is the current HDFC solar loan interest rate in 2026?
HDFC does not publish a separate solar loan rate. Its published rates in October 2026, linked to the RBI repo rate of 5.25%, are 7.75% to 13.20% p.a. for home improvement loans and 8.00% to 13.70% p.a. for home loan top-ups. Your spread depends on your credit profile and loan size. Always confirm the rate in writing before you sign.
How fast is HDFC solar loan approval?
HDFC does not publish a fixed approval time. A top-up is usually quicker because your property and repayment history are already on file; a home improvement loan for a new customer needs fuller documentation and a property check. Ask your loan officer for a timeline when you apply.
Can I get an HDFC solar loan if I don’t have an existing HDFC home loan?
Yes, through HDFC’s home improvement loan, which is secured on your home. For new customers HDFC funds up to 90% of the improvement estimate on loans up to ₹30 lakh, subject to the property’s value and your repayment capacity. Published rates are 7.75% to 13.20% p.a.
What is the processing fee for HDFC solar loan?
For salaried and self-employed professionals, HDFC charges up to 0.50% of the loan amount or ₹4,000, whichever is higher, plus applicable taxes. Self-employed non-professionals pay up to 1.50% or ₹5,000, whichever is higher. Ask about fee waivers, which are sometimes offered during promotions.
Does HDFC solar loan cover the full system cost?
Not always. For new customers the home improvement loan funds up to 90% of the estimate on loans up to ₹30 lakh, so expect to pay about 10% yourself. You can also claim the PM Suryaghar subsidy, which is credited after installation, and use it to prepay part of the loan.
Is HDFC better than SBI for solar loans?
It depends on the rate you are actually offered. HDFC suits existing HDFC home loan customers who can take a top-up. If you have no HDFC home loan, compare the written quotes from HDFC and SBI on rate, fees and prepayment terms. See our full comparison for the complete picture.
What happens if I miss an EMI on my HDFC solar loan?
HDFC charges interest on the unpaid EMI for the number of days it is late, at the loan’s contracted rate, added to your next EMI. Missed payments are also reported to credit bureaus and can lower your score. Set up an ECS mandate to avoid missed payments.
