Lee Residence
- Large-Scale Residential Solar Complex
- System Size: 19.62 kWp
- Completion: 15-May-2023
- San Sebastian, Tarlac City, Philippines
Project Summary
The Lee Residence features a 19.62 kWp fully net-metered solar installation designed to serve both household consumption and electric vehicle charging. The architectural centrepiece is a custom-built solar canopy, engineered not only for vehicle protection but also for optimal solar exposure and structural longevity. By integrating bifacial glass-glass modules across multiple roof sections and the canopy structure, the system maximises generation from both direct and reflected light, increasing overall yield per installed kilowatt.
The engineering brief required clean cable routing, careful load balancing across phases, and precise inverter sizing using premium SMA inverters to ensure stable export and seamless daytime offset. The client adopted the same forward-thinking strategy outlined in Fleet Fuel Savings: EVs & Solar Philippines, combining mobility electrification with rooftop generation to reduce both transport and household operating costs.
Fully compliant with utility net metering protocols, the system consistently offsets daytime demand while exporting surplus energy to subsidise night loads. It stands as a refined example of how residential solar, when engineered correctly, can support EV adoption without compromising reliability or aesthetics.
