Solar Loan & Financing in Tamil Nadu
Go solar with zero upfront cash. Residential loans start from 7% under the PM Surya Ghar concessional scheme (SBI standard rate from 8.15%). Commercial and industrial customers can access MSME loans, SIDBI green finance, and zero-capex OPEX models.

Why Finance Your Solar System?
Concessional Residential Loans
PM Surya Ghar applicants access concessional loans from ~7% via nationalized banks. SBI Surya Shakti offers the best standard rate at 8.15% with no collateral up to ₹7.5 lakh.
EMI < Electricity Savings
For most 3–5 kW systems, revised EMI after subsidy prepayment is ₹1,480–₹3,325/month — typically less than your monthly TANGEDCO bill reduction.
40% Depreciation (Commercial & Industrial)
Under the old IT regime, businesses can write off 40% of solar system cost in Year 1 under the Income Tax Act. Consult your CA to confirm applicability under your chosen tax regime.

How Zero-Cash Solar Works — Step by Step
Solar Financing Across Tamil Nadu
Tristar assists homeowners, businesses and factories with solar loan documentation and bank coordination in every major district. Our installations qualify with all major nationalized banks.
Subsidy Timeline: What to Expect
Installation takes 1–2 days. TANGEDCO net metering inspection follows in 45–90 days. After uploading the commissioning certificate to the PM Surya Ghar portal, the subsidy is credited in 90–120 days. Use it immediately to prepay the loan — banks cannot block this since it is a direct DBT to your account.
