Solar Financing in India: Loans, EMI Plans & Smart Ways to Go Solar

Making Solar Affordable for Every Indian Household

The upfront cost of a rooftop solar system — ₹1,50,000 to ₹6,50,000 for typical residential sizes — is the single biggest barrier to adoption. But you do not need to pay everything upfront. Banks, NBFCs, and solar companies now offer dedicated solar loans, EMI plans, and lease options that let you go solar with little to no down payment.

Solar Vipani partners with verified installers and financing providers to help homeowners across 500+ cities find the right payment plan. Whether you want a bank loan, zero-cost EMI, or a government-backed scheme, this guide covers every option available in India.

What Is Solar Financing?

Solar financing refers to any payment method that spreads the cost of a rooftop solar system over time instead of requiring full upfront payment. In India, the main financing options are:

Solar loans — Dedicated loans from banks (SBI, HDFC, Canara Bank) at 7–10% interest for 3–7 year terms
EMI plans — Monthly instalments offered by solar installers or NBFCs, often at 0% interest for 12–24 months
Government schemes — PM Surya Ghar provides direct subsidy up to ₹78,000, and some states offer additional concessional financing
Solar leasing — A third party installs and owns the system on your roof; you pay a fixed monthly fee lower than your current electricity bill
Green bonds — For commercial and industrial installations, green bond financing offers competitive rates for large-scale solar projects

The right option depends on your budget, system size, and how quickly you want to own the system outright.

Solar Loans from Banks

Major Indian banks now offer dedicated solar loan products with competitive interest rates. These loans are classified as priority sector lending (PSL), which means banks are incentivised to approve them.

Bank	Interest Rate	Tenure	Max Amount	Processing Fee
SBI	7.00–7.75%	Up to 10 years	₹10,00,000	0.50%
HDFC	8.50–9.50%	Up to 7 years	₹10,00,000	1.00%
Canara Bank	7.25–8.25%	Up to 7 years	₹10,00,000	0.50%
Bank of Baroda	7.50–8.50%	Up to 7 years	₹10,00,000	0.50%
PNB	7.50–8.75%	Up to 7 years	₹10,00,000	1.00%

SBI's Surya Shakti solar loan is the most popular choice — low interest, long tenure, and integration with PM Surya Ghar subsidy disbursement.

EMI Plans: Pay Monthly, Save Immediately

Many solar installers offer EMI plans that let you start saving on electricity bills from day one. The monthly EMI is typically less than your current electricity bill, making solar cash-flow positive from the first month.

For a 3kW system costing ₹1,40,000 after subsidy, here is what EMIs look like:

Tenure	Interest	Monthly EMI	Total Cost
12 months	0%	₹11,667	₹1,40,000
24 months	8%	₹6,320	₹1,51,680
36 months	9%	₹4,450	₹1,60,200
60 months	10%	₹2,975	₹1,78,500

Zero-cost EMI options (12–24 months) are offered by many installers during promotional periods. The installer absorbs the interest cost as a customer acquisition expense.

Government Schemes That Reduce Your Financing Need

The PM Surya Ghar Yojana reduces your upfront cost by up to ₹78,000 for a 3kW system. This subsidy is applied after installation, but many banks now pre-approve loans factoring in the expected subsidy amount, effectively reducing the loan principal.

Some states offer additional incentives:

Interest subvention — Select states subsidise 2–3% of the loan interest rate
Top-up subsidy — Additional state subsidy on top of the central ₹78,000
Tax benefits — Commercial installations can claim accelerated depreciation (40%) under the Income Tax Act

ROI: Why Solar Is a Better Investment Than FDs

Solar is not just an expense — it is an investment with measurable returns. A rooftop solar system delivers 15–25% annual returns, far exceeding fixed deposits (6–7%) or PPF (7.1%).

Payback period: 3–6 years after subsidy
System lifespan: 25+ years with warranty
25-year savings: ₹4,00,000–₹15,00,000 depending on system size and tariff growth
Tariff hedge: Electricity prices rise 5–8% annually; solar locks in your cost at ₹0 after payback

Even with a loan at 8% interest, the effective return on solar remains well above 12% because electricity savings outpace interest costs from year one.

Lease vs Loan: Which Is Right for You?

Not sure whether to buy or lease? Here is a quick comparison:

Factor	Solar Loan	Solar Lease
Ownership	You own the system	Leasing company owns it
Upfront cost	0–20% down payment	Zero
Monthly payment	EMI (fixed)	Lease rent (fixed)
Subsidy eligibility	Yes	No (company claims it)
Maintenance	Your responsibility	Lessor handles it
25-year savings	Higher (you own it)	Lower (you pay rent)

For most homeowners, a solar loan offers better long-term value because you own the system and claim the subsidy. Leasing suits those who want zero hassle and are okay with lower total savings.

Financing for Commercial Solar Projects

Commercial and industrial (C&I) solar projects above 10kW have different financing structures. Options include project finance, operating leases, RESCO (renewable energy service company) models, and green bonds.

Key advantages for businesses:

Accelerated depreciation — Claim 40% depreciation in the first year under Income Tax Act
Lower cost of capital — Priority sector lending rates apply
RESCO model — Zero capex; pay only for the electricity generated at a pre-agreed rate
Green certification — Solar installations qualify for IGBC/LEED green building credits

Common questions

Can I get a solar system with zero down payment?

Yes. Several banks and NBFCs offer 100% financing for rooftop solar systems. SBI's Surya Shakti loan covers the full system cost. Many installers also offer zero-down EMI plans for 12–24 months. With PM Surya Ghar subsidy reimbursed post-installation, your effective out-of-pocket cost can be minimal.

What is the interest rate on solar loans in India?

Solar loan interest rates range from 7% to 10% depending on the bank and your credit profile. SBI offers the lowest rates at 7.00–7.75%. Since solar loans are classified as priority sector lending, banks are incentivised to offer competitive rates. Some installers offer 0% EMI for 12–24 month tenures.

Is it better to buy solar panels outright or take a loan?

If you have the funds, buying outright gives the highest total savings since you avoid interest costs. However, a solar loan still makes financial sense — the electricity savings exceed the EMI from month one in most cases. Even at 8–10% interest, solar delivers 15%+ annual returns, making it a positive-NPV investment.

How long does it take to recover the cost of solar panels?

Most homeowners recover their investment in 3–6 years. If you pay upfront with subsidy, payback is 3–4 years. With a loan, the payback period extends to 5–7 years including interest, but you start saving from day one since EMI is typically less than your electricity bill. After payback, savings are pure profit.

Can I claim tax benefits on solar panel installation?

Residential consumers cannot claim income tax deductions on solar installations. However, commercial and industrial consumers can claim accelerated depreciation of 40% in the first year under the Income Tax Act, significantly reducing their effective tax liability and improving project ROI.

What documents do I need for a solar loan?

Most banks require identity proof (Aadhaar/PAN), address proof, income proof (salary slips or ITR), bank statements for 6 months, electricity bill copy, and a quotation from the solar installer. Some banks also require property ownership proof. The installer typically assists with the loan application process.
