Should you write a cheque or take the PM Surya Ghar 7% collateral-free loan? A practical ROI comparison with real 2026 numbers.
The PM Surya Ghar loan in one paragraph
Under the scheme, residential consumers can avail a collateral-free loan of up to ₹2 lakh at 7% effective interest for systems up to 3 kW. The disbursal happens via partner banks (SBI, Canara, PNB and others) and the subsidy is netted directly against the loan.
Scenario A — Upfront payment
3 kW system @ ₹2,10,000. Net of ₹78,000 central subsidy = ₹1,32,000. Annual bill saving ₹54,000. Payback ~ 2.5 years. Years 3–25 are pure savings of ₹13–14 lakh (with 5% tariff inflation).
Scenario B — Loan financed
Same 3 kW system. You pay only the GST + processing — about ₹15,000 upfront. EMI of ~₹2,600/month for 5 years. Your monthly bill saving (≈ ₹4,500) covers the EMI from month one, leaving ~₹1,900 net positive cash every month.
Verdict
If you have the cash, paying upfront yields the highest absolute return. If you do not, the PM Surya Ghar loan is genuinely cash-flow positive from day one — a rare deal in Indian retail finance. Either way, you win.
