How PM Surya Ghar Subsidy Works with Your Loan
- Take a solar loan for the full gross system cost (₹1.65–1.80 lakh for 3kW).
- Installation is completed by MNRE-empanelled vendor — typically 2–4 days.
- DISCOM installs net meter — typically 15–30 days after installation.
- ₹78,000 subsidy credited to your bank account within 30 days of commissioning.
- Prepay ₹78,000 to your solar loan — reduces outstanding principal and future EMIs.
Result: You effectively borrowed ₹1.65–1.80 lakh but only paid ₹87,000–₹1.02 lakh in EMIs.
EMI vs Savings: Does Solar EMI Pay for Itself?
| System | Net Cost (Post-Subsidy) | EMI @ 7.2% / 7yr | Monthly Savings (₹9/unit) | Net Monthly Gain |
|---|---|---|---|---|
| 1 kW | ₹30,000 | ₹458/mo | ₹900/mo | +₹442/mo |
| 2 kW | ₹50,000 | ₹763/mo | ₹1,800/mo | +₹1,037/mo |
| 3 kW | ₹1,02,000 | ₹1,557/mo | ₹2,900/mo | +₹1,343/mo |
| 5 kW | ₹2,22,000 | ₹3,389/mo | ₹4,500/mo | +₹1,111/mo |
Key insight: For every system size, your monthly savings are higher than your EMI. You generate positive cash flow from month 1 — no waiting for payback period.
RESCO / Zero Down Model — Pay Only for Units Generated
Don't want a loan at all? Some installers and NBFCs offer a RESCO (Renewable Energy Service Company) model:
- You pay ₹0 upfront
- The RESCO installs the system on your rooftop at their cost
- You buy the electricity generated at a pre-agreed rate (₹4–6/unit) — lower than grid tariff
- You save on your bill from day one without any investment
- Ownership transfers to you after 10–15 years
The downside: you don't get the PM Surya Ghar subsidy and you don't own the system for the first decade. But for cash-constrained homeowners, it's a genuine zero-risk option.
Tips to Get the Best Solar Loan Rate
- Apply to SBI or Bank of Baroda first — they have dedicated solar schemes with the lowest rates (7.2–7.5%)
- Keep your CIBIL score above 700 for best rates
- Show the government portal registration (pmsuryaghar.gov.in) to the bank — it strengthens your application
- Ask for the loan under the PM Surya Ghar scheme, not a generic personal loan (personal loan rates are 12–18%)
