Project Details: 3kW Residential On-Grid Solar in Mogappair
This case study documents the technical engineering design and net-metering integration executed by IKIGAI GLOBAL for Mrs./Mr. Balaji Swaminathan in Mogappair, Chennai. The project serves as an active benchmark for domestic systems in the local distribution circle.
1. Operational Challenge
Client wanted to minimize visual clutter on his flat domestic concrete rooftop while maximizing output.
2. Engineered Solution
Designed a low-profile GI mounting structure aligned at a 13-degree tilt angle to minimize space while keeping clean layout aesthetics.
3. Bill of Materials (BoM) & Specifications
| Component | Specification Details |
|---|---|
| Solar Modules | 6 x 550W Mono PERC Modules |
| Solar Inverter | 3kW Grid-Tie Inverter |
| Mounting Structure | Anchor fast-fasteners and customized elevations GI profiles |
| Grid Connection | TANGEDCO Bidirectional Net-Metering Approval |
4. Financial Yield and Performance Audit
Since commissioning on 2026-04-10, the array has consistently yielded 4.1 kWh/kWp daily, aligning with our original PVSyst generation profiles. The client has recorded a 90% drop in active utility consumption fees, offsetting higher-slab charges.
