Tell us your monthly electricity bill and roof size — we'll estimate your ideal system, upfront cost, subsidy, and 25-year savings.
All fields optional — defaults are typical Chennai numbers.
Estimated 25-year savings
No magic. Just industry standards and Tamil Nadu specifics.
We assume a 1 kW system generates about 4.5 units per day in Chennai — roughly 135 units per month. Your system is sized to offset your bill, capped by available roof space (~80 sq ft per kW).
Residential on-grid systems are costed at ₹55,000 per kW; commercial at ₹50,000 per kW. This includes panels, inverter, mounting, cabling, net-metering, and installation labor — but can vary by panel brand and site conditions.
Under the PM Surya Ghar Muft Bijli Yojana, residential systems receive up to ₹78,000 subsidy (₹30,000 for first kW, ₹18,000 for second, ₹6,000 per additional kW beyond 3 kW). We handle the paperwork.
We assume your current bill is eliminated for ~11 months and factor in a small monsoon reduction. Payback = net investment ÷ annual savings. Most Chennai residential systems pay back in 3–5 years.
Tier-1 solar panels carry a 25-year performance warranty. We assume annual electricity tariffs rise 3% per year, so your cumulative savings compound over time.
Each kWh of grid electricity in India emits roughly 0.82 kg of CO₂. We convert your lifetime solar generation into tons of CO₂ avoided — a rough but meaningful number.
