Estimated prices as of November 2026 for a residential on-grid system (DCR panels, inverter, GI structure, wiring, earthing, net-meter paperwork). Subsidy = PM Surya Ghar central assistance + UP state top-up, credited to your bank account after commissioning, subject to official approval. Final price after a free site survey.
Which size do I need?
In Lucknow and Azamgarh, every kWp of panels makes about 120 units a month (≈4 units a day, yearly average). A "3 kW" system uses 6 × 575 Wp panels = 3.45 kWp, so it makes about 414 units a month. On the UPPCL domestic tariff, a ₹2,500 monthly bill is about 350 units → a 3 kW system; a ₹5,000 bill is about 666 units → 5.5 kW.
- 1 kW (2 panels, ~92 sq ft): small homes, ~138 units/month — you pay about ₹15,000.
- 2 kW: ~276 units/month — you pay about ₹30,000.
- 3 kW: the sweet spot — maximum central subsidy (₹78,000) — about ₹72,000.
- 5 kW: homes with 2+ ACs, ~621 units/month — about ₹1,82,000.
- 10 kW: large homes/shops — about ₹4,57,000 (subsidy is capped).
What decides the final price?
- Panel type — DCR (made-in-India cells) panels are required for the subsidy; mono-PERC/TOPCon/bifacial cost more but produce more.
- Structure height — an elevated GI structure (so you can still use the terrace) costs more than a low one.
- Battery backup — a hybrid inverter with lithium battery adds roughly ₹40,000 + ₹15,000/kW; the battery part gets no subsidy.
- Cable length & roof access — long DC/AC runs, multi-storey buildings or shading fixes.
Payback and 25-year savings
After subsidy, a 3 kW system typically pays for itself in about 2.3 years — that is when the bill savings add up to what you paid; every year after that is profit; panels carry long performance warranties and keep producing for 25+ years.
