Solar Savings Calculator — Frequently Asked Questions

Q.How accurate is this solar savings calculator?

Within 5–7% of actual savings when bill, location, and roof area are entered correctly.

The calculator uses MNRE official benchmark costs (₹45,000–₹65,000 per kW after subsidy for residential systems), RREC Rajasthan top-up data (₹17,000 for systems up to 3 kW), and average Jaipur solar generation (4.5 kWh per kW per day). When you enter your real bill and roof area, the savings estimate falls within 5–7% of what an MNRE-empanelled vendor will quote — based on 187+ households we have guided through this process.

Q.What information do I need to use the calculator?

Just your monthly electricity bill in ₹ and (optionally) your rooftop area in square feet.

You only need (1) your average monthly bill in rupees, (2) your city or state for tariff slabs, and (3) optional: shadow-free rooftop area in sq ft. The calculator auto-recommends the right system size (kW), monthly savings, payback period, central subsidy amount, and state top-up if applicable.

Q.Does this calculator include central + state subsidies for Rajasthan?

Yes — central ₹78,000 max + RREC top-up ₹17,000 for Rajasthan residents.

Yes. For residents in Rajasthan, the calculator factors in both the central PM Surya Ghar subsidy (₹30,000/kW up to 2 kW + ₹18,000/kW for the 3rd kW; capped at ₹78,000) AND the RREC top-up of ₹17,000 for systems up to 3 kW. For other states the calculator applies state-specific top-ups where available.

Q.What is the typical payback period for a residential rooftop solar in Jaipur?

Typically 3.5–5 years for a 3 kW system in Jaipur after central + state subsidies.

Based on 187+ Jaipur households we have guided: a 3 kW system costing ~₹2.0 lakh upfront (post 25% panel-cost subsidy + RREC top-up) saves ₹3,500–₹4,500 per month on JVVNL bills. Payback typically lands at 3.5–5 years, with 20+ years of free electricity after that. For premium homes with 5–10 kW the payback is similar (4–5 years) due to higher monthly savings.

Q.Is the calculator output binding on installers?

No — it is an educational estimate. Real quotes come from MNRE-empanelled vendors.

No. The calculator gives an educational, NGO-prepared estimate. The final binding quote MUST come from an MNRE-empanelled vendor after a physical roof survey. We are an NGO — we do not sell or install systems. We help you understand what is fair and verify quotes against MNRE benchmark costs before you sign.
