Project Details: 8kW Residential On-Grid Solar in Kolathur
This case study documents the technical engineering design and net-metering integration executed by IKIGAI GLOBAL for Mrs./Mr. . Meenakshi Sundaram in Kolathur, Chennai. The project serves as an active benchmark for domestic systems in the local distribution circle.
1. Operational Challenge
High domestic load due to multiple AC units pushing billing rates into the highest TNEB tariff brackets.
2. Engineered Solution
Installed an 8kW system that offsets TANGEDCO imports. Secured immediate net-metering commissioning to cut bills by 90%.
3. Bill of Materials (BoM) & Specifications
| Component | Specification Details |
|---|---|
| Solar Modules | 15 x 550W Mono-Crystalline Modules |
| Solar Inverter | 8kW Three Phase 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 2026-03-22, 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.
