State Bank of India (SBI) is the most widely used lender for residential solar projects in India, and for good reason. With interest rates starting at 8.5% — the lowest among major banks in 2026 — and loan amounts up to ₹30 lakh, SBI’s solar loan products make rooftop solar accessible to salaried and self-employed homeowners across the country. Their branch network covers every district, loan officers are familiar with MNRE documentation, and the processing fee is among the lowest in the market at 0.35%.
Key takeaway. SBI solar loans in 2026 start at 8.5% interest for high-credit-score applicants under the SBI Green Home Loan and SBI Saral Solar schemes. The maximum loan is ₹30 lakh with tenure up to 15 years. A ₹2 lakh loan at 8.5% over 10 years has an EMI of approximately ₹1,976 per month. Heaven Green Energy is MNRE-empanelled and can provide SBI-ready quotations for faster loan processing.
This guide covers everything you need to know: exact rates, EMI tables, eligibility rules, required documents, and the application process step by step.
SBI Solar Loan Products: Green Home Loan vs. Saral Solar
SBI offers solar financing under two product variants depending on your profile:
SBI Green Home Loan (Solar Add-on): This is a top-up loan available to existing or new SBI home loan borrowers who want to add a rooftop solar system to a financed property. It is linked to the home loan account and carries the same rate as your home loan (floating, MCLR-linked). This is typically the cheapest option for homeowners who already have an SBI home loan.
SBI Saral Solar: This is a standalone solar loan product for property owners who don’t have an existing SBI home loan. It operates as a secured personal/consumer loan against the solar plant as primary collateral (for loans up to ₹10 lakh) or against the property for larger amounts. The rate is slightly higher than the Green Home Loan add-on.
Both products were substantially revised in 2024–25 to align with PM Suryaghar implementation and now explicitly accept MNRE-empanelled installers’ quotations as the primary cost basis.
💡 Fast tip
If you have an existing SBI home loan, ask your home loan branch about a solar add-on before applying for Saral Solar. The add-on rate is typically 0.25–0.50% lower and processing is faster because your KYC is already on file.

Income proof (salaried):

- Last 6 months’ bank statements (salary account)
Income proof (self-employed):
- Last 3 years’ ITR with computation

- Quotation from MNRE-empanelled installer with HSN code breakup
- Installer’s MNRE empanelment certificate
- DISCOM sanction letter for net metering (or proof of application)
- Site photos (roof access, area available)
Heaven Green Energy provides the last three items — empanelment certificate, a fully detailed quotation with HSN codes, and DISCOM application support — as standard service to all clients seeking SBI financing.
Step-by-Step SBI Solar Loan Application Process
- Check your CIBIL score. Pull a free report at CIBIL’s official site — this is the first filter SBI applies. If below 700, work on improving it for 3–6 months before applying.
- Get a quotation from an MNRE-empanelled installer. The quotation must include system specifications, HSN code breakup, and the installer’s MNRE empanelment number. Contact Heaven Green Energy or verify empanelment at MNRE’s empanelled vendor list.
- Apply for DISCOM net metering sanction. Submit the net metering application to your local DISCOM (UGVCL/DGVCL/PGVCL/MGVCL in Gujarat). SBI typically needs proof of application — the sanction itself can come after loan approval.
- Visit the nearest SBI branch or apply online. SBI’s YONO app and website support solar loan pre-applications. Carry physical documents for the in-branch verification.
- Submit the complete document package. A single complete submission is much faster than multiple visits. Use the checklist above.
- Property valuation. For loans above ₹10 lakh, SBI will depute a valuer to inspect the property. This takes 3–7 working days.
- Loan sanction. For complete applications, SBI targets sanction within 7–10 working days. Common delays: missing income documents, property title disputes, or DISCOM sanction not yet received.
- Disbursement. Loan is disbursed directly to the installer upon submission of a proforma invoice. SBI does not give cash — they transfer directly to the vendor’s account.
- Installation and commissioning. Heaven Green Energy typically completes installation within 7–15 days of loan disbursement.
- EMI begins. The first EMI is due one month after disbursement. Set up an auto-debit to avoid missed payments.
⚠️ Watch out
SBI disbursement goes directly to the installer, not to you. Make sure your installer has a valid business bank account linked to their GSTIN — SBI will verify this. Some small local installers fail this check.
SBI Solar Loan vs. Personal Loan for Solar: Why the Difference Matters
Some homeowners, unable to produce property documents, ask whether a personal loan for solar makes sense. The comparison is stark:
| Factor | SBI Solar Loan | Personal Loan for Solar |
|---|---|---|
| Interest rate | 8.5–9.5% | 14–18% |
| Tenure | Up to 15 years | Up to 5 years |
| EMI (₹2L, 10yr) | ₹1,976–₹2,070 | ₹4,647–₹4,921 (5yr) |
| Total interest (₹2L) | ₹37,120–₹44,400 | ₹58,800–₹75,260 |
| Processing fee | 0.35% | 1–3% |
| Collateral | Property/solar plant | None |
The personal loan costs ₹30,000–₹50,000 more in total interest on a ₹2 lakh borrowing. Always opt for the secured solar loan if you can produce property documents.
Pros and Cons of SBI Solar Loan
- Lowest rate among major banks — 8.5% starting
- Lowest processing fee — 0.35%
- No prepayment penalty after 12 EMIs
- Widest branch network — available in every district
- Slower approval than private banks — 7–15 days
- Property documents mandatory above ₹10 lakh
- Branch-level variability in solar loan familiarity
- Floating rate — EMI may increase if MCLR rises

Frequently Asked Questions
What is the interest rate on SBI solar loan in 2026?
SBI solar loan interest rates in 2026 range from 8.5% to 9.5% per annum, linked to the SBI 1-year MCLR. Applicants with a CIBIL score of 800 or above qualify for the base rate of 8.5% under the Green Home Loan solar add-on. Saral Solar standalone applicants typically see rates of 8.75–9.5%. Rates are floating and change with MCLR revisions.
What is the maximum SBI solar loan amount I can get?
The maximum loan under SBI Green Home Loan solar add-on and SBI Saral Solar is ₹30 lakh for residential applicants. Commercial and MSME applicants can access higher amounts under SBI’s MSME or business loan products. For most residential rooftop systems (3–10 kW), the required loan after PM Suryaghar subsidy is ₹1.5–5 lakh — well within the limit.
Does SBI require DISCOM sanction letter for solar loan?
SBI requires proof that you have applied for net metering with your DISCOM — the actual sanction letter is preferred but not always required at the time of loan application. Some branches accept the DISCOM application acknowledgment. Heaven Green Energy files the DISCOM application on your behalf and provides the acknowledgment within 3–5 working days.
How long does SBI solar loan approval take?
With a complete document package, SBI targets approval in 7–15 working days. Common reasons for delay: incomplete income documents, property title in dispute, DISCOM application not filed, or installer not MNRE-empanelled. Heaven Green Energy clients typically see faster processing because our documentation package is SBI-standard from day one.
Can I get an SBI solar loan without salary slip?
Self-employed applicants can get SBI solar loans using ITR (last 3 years), CA-certified financials, and bank statements instead of salary slips. The income eligibility rule is the same — net monthly income must be at least 3× the EMI. Farmers can access solar loans under different SBI agricultural schemes — see NABARD’s guidelines on agri-solar financing for rural applicants.
Is there a prepayment penalty on SBI solar loans?
SBI does not charge a prepayment penalty on floating-rate loans after the completion of 12 EMIs. If you prepay within the first 12 months, a 1% prepayment charge applies. After 12 EMIs, you can make part-prepayments or full foreclosure without any penalty — useful when your electricity savings accumulate faster than expected.
What if I can’t produce property documents for SBI solar loan?
For loans up to ₹10 lakh under Saral Solar, SBI can accept the solar plant as the primary collateral (without property mortgage) for applicants with strong income and credit scores. For amounts above ₹10 lakh, property documents are mandatory. If you are a tenant and own no property, consider the HDFC solar top-up (if HDFC home loan exists) or look at fintech NBFC solar loan options.
