A 3 kW TATA Power Solar install in Gomti Nagar — the timeline, the paperwork, and the real bill before and after.
The customer
The Verma family — a four-member household in Gomti Nagar, Lucknow. Pre-solar bill: ₹7,200 average across summer months on a 4 kW sanctioned MVVNL connection. Daily consumption: ~24 units.
The system
A 3 kW on-grid system using TATA Power Solar mono PERC panels and a string inverter. Total panels: 6. Roof area used: ~28 sq m on the south-east facing portion. Cabling, ACDB/DCDB and earthing per IEC norms.
The paperwork
PM Surya Ghar portal registration → MVVNL technical feasibility (16 days) → installation (2 days) → net-meter application → DISCOM inspection → commissioning certificate. Total cycle time: 38 days. Subsidy of ₹78,000 (central) + ₹30,000 (UPNEDA) credited 21 days post-commissioning.
The result
First post-solar bill: ₹180 (fixed charges only). Annual saving projected at ₹78,000+. Payback period at the family's tariff slab: 2.7 years. The Vermas are exporting roughly 80 units back to the grid every month — and the JEE who inspected the system referred two neighbours to us.
