HDFC Bank is the largest private-sector lender for solar installations in India, offering faster approvals and more flexible product structures than most public sector banks. Their solar loan products are available as a top-up on existing HDFC home loans (the fastest route) or as standalone solar loans for non-HDFC customers. In 2026, HDFC’s rates of 9.0–10.5% are slightly higher than SBI’s 8.5–9.5%, but their approval speed — often 48–72 hours for existing customers — and digital processing make them the preferred choice for buyers who need quick disbursement.
Key takeaway. HDFC solar loans in 2026 carry interest rates of 9.0–10.5% per annum, with maximum loan amounts up to ₹30 lakh and tenure up to 15 years. Existing HDFC home loan customers get preferential rates at the lower end (9.0–9.25%) with same-week approval. A ₹2 lakh HDFC solar loan at 9.5% over 10 years has an EMI of approximately ₹2,070. Heaven Green Energy is empanelled with HDFC and can prepare your loan documentation package within 24 hours.
This guide covers HDFC’s product variants, exact rates for 2026, EMI tables, eligibility criteria, the document checklist, and a step-by-step application guide.
HDFC Solar Loan Products: Top-Up vs. Standalone
HDFC’s solar financing comes in two forms:
HDFC Home Loan Solar Top-up: For customers who already have an HDFC home loan, a solar top-up is the simplest and fastest route. HDFC treats it as an extension of the existing loan — minimal fresh KYC, no new property valuation needed for amounts within 80% LTV, and same-week approval in most cases. The rate is the same as the existing home loan rate (typically RPLR minus a spread), making it the cheapest HDFC solar option.
HDFC Green Personal/Consumer Loan (standalone solar): For non-HDFC customers or buyers who want a separate solar loan account, HDFC offers a green-category consumer loan. The rate is 0.5–1.0% higher than the top-up product, and documentation requirements are more extensive. However, HDFC’s digital-first processing (photo upload, video KYC) makes this faster than most banks’ paper-based processes.
Understanding which product fits your profile before approaching HDFC saves significant time. Heaven Green Energy’s finance team can advise on this in a 15-minute consultation — contact us here.
💡 Fast tip
HDFC's relationship managers at home loan branches have solar loan authority. If you apply at a standard HDFC branch that does not handle home loans, you may be redirected — go directly to the home loan division from the start.
HDFC Solar Loan Interest Rates 2026
| Product | CIBIL Score | Interest Rate | Rate Type |
|---|---|---|---|
| Solar top-up (existing HL customer) | ≥ 800 | 9.00% p.a. | Floating (RPLR-linked) |
| Solar top-up (existing HL customer) | 750–800 | 9.25% p.a. | Floating |
| Standalone solar loan | ≥ 800 | 9.50% p.a. | Floating |
| Standalone solar loan | 700–800 | 9.75–10.00% p.a. | Floating |
| Standalone solar loan | 650–700 | 10.00–10.50% p.a. | Floating |
Source: HDFC Home Loans rate cards and RPLR schedule, June 2026. HDFC’s RPLR stood at approximately 18.40% in June 2026; solar loans are priced at RPLR minus a fixed spread.
The key point: existing HDFC home loan customers get a rate equivalent to SBI for good-credit applicants. New-to-HDFC borrowers pay a modest premium for the convenience and speed.
HDFC Solar Loan EMI Tables
EMI calculations at 9.5% for various loan sizes and tenures:
| Loan Amount | 5 years | 10 years | 15 years |
|---|---|---|---|
| ₹1,00,000 | ₹2,100 | ₹1,296 | ₹1,044 |
| ₹2,00,000 | ₹4,199 | ₹2,593 | ₹2,089 |
| ₹3,00,000 | ₹6,299 | ₹3,889 | ₹3,133 |
| ₹5,00,000 | ₹10,498 | ₹6,481 | ₹5,222 |
| ₹10,00,000 | ₹20,997 | ₹12,963 | ₹10,443 |
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 75–80% solar offset).
HDFC Solar Loan Eligibility Criteria
Who can apply:
- Salaried individuals at private, public, or MNC companies with minimum 2 years’ continuous employment
- Self-employed professionals and business owners with 3+ years’ business vintage

Property and security:
- Must own the property where solar is being installed
- For top-up loans: property already mortgaged to HDFC
- For standalone loans above ₹10 lakh: fresh property mortgage required
- For amounts up to ₹10 lakh: solar plant as primary collateral considered for strong credit profiles
Income criteria:
- HDFC uses the Fixed Obligations to Income Ratio (FOIR) — total EMIs (including new solar EMI) must not exceed 40–50% of gross monthly income
- Example: For a ₹5 lakh solar loan over 10 years at 9.5% (EMI ₹6,481), gross monthly income must be at least ₹12,962–₹16,203

- Check your CIBIL report before applying — HDFC runs a hard pull that affects your score
Documents Required for HDFC Solar Loan
For existing HDFC home loan customers (solar top-up):
- Completed application form (digital or physical)
- Solar installer quotation with system specs and HSN codes
- MNRE empanelment certificate of installer
- Latest electricity bill (for consumption profile)
- Current bank account statement (3 months) if additional income assessment needed
For new HDFC customers (standalone solar loan):
- Aadhaar + PAN card
- 3 months’ salary slips (salaried) or 3 years’ ITR (self-employed)
- 6 months’ bank statements (salary or current account)
- Property documents (title deed, property tax receipt)

The HDFC Solar Loan Application Process: Step by Step
- Determine which product applies. Do you have an existing HDFC home loan? → Solar top-up. No existing HDFC relationship? → Standalone green solar loan. This choice determines your application path and rate.
- Pull your CIBIL score. Know your score before HDFC runs a hard inquiry. Target 750+ for competitive rates. HDFC also considers their internal credit scoring (HDFC Credit Bureau data) for existing customers.
- Get your solar installer quotation. The quote must be from an MNRE-empanelled vendor. It must include: system size in kW, panel and inverter model numbers, HSN code for each component, installation charges, and total project cost. Heaven Green Energy prepares this in 24 hours.
- Initiate DISCOM net metering application. HDFC increasingly asks for this proof. In Gujarat, this is submitted to UGVCL/DGVCL/MGVCL/PGVCL online portals. We file this on your behalf.
- Apply online or at branch. HDFC’s home loan portal allows digital solar top-up applications with document upload. For standalone loans, visit the home loan branch (not the consumer banking branch).
- Submit documents. Complete submission upfront prevents the back-and-forth that causes delays. Use the checklist in the previous section.
- Property valuation (if applicable). For new standalone loans above ₹10 lakh, HDFC deputes an external valuer. This takes 3–5 working days.
- Sanction letter. Issued after credit and valuation clearance — typically in 3–7 working days for top-ups, 7–14 days for standalone.
- Disbursement. HDFC disburses directly to the installer’s bank account upon submission of the installer’s GST invoice. No cash disbursement.
- EMI auto-debit setup. Activate ECS/NACH from your salary or savings account. First EMI is due 30 days after disbursement.
⚠️ Watch out
HDFC's foreclosure charge of 2% within the first 36 months catches many buyers who plan to prepay from their first-year electricity savings. If you expect to repay early, consider SBI's no-penalty prepayment structure instead.
Comparing HDFC with Other Solar Lenders
For a full comparison of all major lenders, see our solar loan EMI comparison 2026. The quick summary:
| Factor | HDFC | SBI | IREDA |
|---|---|---|---|
| Rate | 9.0–10.5% | 8.5–9.5% | 8.75–10.5% |
| Max amount | ₹30 lakh | ₹30 lakh | ₹50 lakh (comm.) |
| Speed | 48–72 hrs (top-up) | 7–15 days | 15–30 days |
| Foreclosure penalty | 2% (first 36 months) | None after 12 EMIs | Varies |
| Digital process | Strong | Moderate | Limited |
| Best for | Existing HDFC HL customers; speed-priority buyers | CIBIL 750+, cost-priority buyers | Commercial projects |
Verdict. HDFC is the best choice when speed matters and you already have an HDFC home loan. For the lowest rate, SBI wins. For commercial-scale projects, IREDA offers the most competitive structure.
Common Mistakes Buyers Make with HDFC Solar Loans
-
1
Applying at a consumer branch instead of home loan branch — HDFC's consumer branches cannot sanction solar loans. Only the home loan and mortgage division has authority.
-
2
Using a non-empanelled installer's quote — HDFC will not disburse to an installer whose MNRE empanelment cannot be verified. Always use an empanelled EPC like Heaven Green Energy.
-
3
Not accounting for the 2% foreclosure fee in ROI calculations — if you plan to close the loan in year 2 using saved electricity money, the 2% fee erodes your savings. Factor it in before deciding to prepay early.
-
4
Skipping the DISCOM application step — HDFC now requires at minimum proof that the net metering application has been filed. Without this, disbursement may be delayed even after sanction.
Pros and Cons of HDFC Solar Loan

Frequently Asked Questions
What is the current HDFC solar loan interest rate in 2026?
HDFC solar loan rates in 2026 range from 9.0% to 10.5% per annum, linked to HDFC’s RPLR. Existing HDFC home loan customers with a CIBIL score above 800 qualify for 9.0–9.25%. New customers with CIBIL 800+ typically see 9.5%. Rates are floating and revised with RPLR changes. Always confirm the rate in writing from your relationship manager on the day you lock in your loan.
How fast is HDFC solar loan approval?
For existing HDFC home loan customers applying for a solar top-up with complete documents, approval takes 48–72 hours. For new-to-HDFC borrowers using the standalone product, approval takes 7–14 working days. The biggest speed difference comes from skipping fresh property valuation for top-up customers.
Can I get an HDFC solar loan if I don’t have an existing HDFC home loan?
Yes. HDFC offers a standalone solar loan (green consumer loan product) for non-HDFC customers. The rate is 9.5–10.5% depending on your credit profile, and property documents are required for loans above ₹10 lakh. The application process is longer than a top-up but still faster than most public sector banks.
What is the processing fee for HDFC solar loan?
HDFC charges a processing fee of 0.5–1.0% of the loan amount plus 18% GST. For a ₹3 lakh loan, this works out to ₹1,500–₹3,000 plus GST. This is higher than SBI’s 0.35% but negotiable for existing premium customers. Ask your relationship manager about fee waivers — these are sometimes available for existing customers or during promotional periods.
Does HDFC solar loan cover the full system cost?
HDFC will typically lend up to 80–90% of the project cost (LTV ratio). You need to bring 10–20% as a down payment or apply for the PM Suryaghar subsidy first and then finance the residual. For a ₹2,00,000 system (after subsidy), HDFC would lend ₹1,60,000–₹1,80,000 and you cover ₹20,000–₹40,000.
Is HDFC better than SBI for solar loans?
HDFC is better when speed is the priority and you already have an HDFC home loan — same-week approval vs. SBI’s 7–15 days. SBI is better when cost is the priority — SBI’s 8.5% starting rate is 0.5–0.75% lower than HDFC’s best rate, saving ₹10,000–₹15,000 on a ₹2 lakh loan over 10 years. See our full comparison for the complete picture.
What happens if I miss an EMI on my HDFC solar loan?
HDFC charges a penal interest of 2% per annum on the overdue amount for late payment. A missed EMI also triggers a negative CIBIL report after 30 days of default. Set up an ECS mandate to prevent missed payments — HDFC’s mobile app sends reminders 7 days before the due date.
