3.3 kW Rooftop Solar Installation in Kankarbagh, Patna
A 3-storey residential home in Kankarbagh, Patna with heavy air conditioning loads during summer. Shree Laxmi Traders designed an elevated galvanized structure to preserve rooftop terrace space while maximizing solar irradiance.
Electricity Bill Comparison: Before vs After
Prior to rooftop solar, high summer electricity usage drove billing into the highest tariff slabs.
Solar generation meets virtually the entire daytime load, leaving only basic fixed meter connection charges.
The Challenge
The homeowner wanted to retain usable rooftop terrace space for evening gatherings while generating enough power to offset 2 AC units and a refrigerator during hot summer months.
The Engineering Solution
Engineered a custom 7-foot elevated hot-dip galvanized mounting structure angled at 25 degrees south. Installed 6 high-efficiency 550W mono PERC bifacial panels coupled with dual-MPPT grid-tied inverter and dedicated copper chemical earthing.
