What the client was facing
Rising electricity bills of ₹5,400/month due to 3 ACs and home office usage. The Sharma family wanted energy independence without relying on unreliable DISCOM supply during summer peaks.
The system we designed
We designed a 5 kW on-grid system with 12× 415W Waaree mono PERC panels, a 5 kW Sungrow string inverter, and net-metering integration with DHBVN. Layout optimized for south-west roof with tile-friendly mounting.
How we executed
Day 1: Free site survey & shadow analysis. Week 1: System design + PM Surya Ghar subsidy application. Week 3: Panel + inverter delivery + 2-day installation. Week 5: DISCOM net-metering approval & commissioning.
The numbers that matter
Monthly bill dropped from ₹5,400 to ₹180 (fixed charges only). Annual savings: ₹64,800. Government subsidy received: ₹78,000. Payback period: 4.9 years. Next 20 years: effectively free power.
"Ojas ne pura subsidy paperwork kiya, installation bhi 2 din me complete. Ab AC chalte rehte hain, bill zero aata hai. Highly recommended."
