O'Driscoll Residence
- Grid-Tied Solar Setup with Night-Time Export Credit
- System Size: 14.17 kWp
- Completion: 1-Jul-2023
- Tarlac City, Philippines
Project Summary
For expatriates living in the Philippines, the electricity bill is often the first financial surprise. Grid rates that are among the highest in Southeast Asia hit hardest when you are running a home sized for comfort: air conditioning, water heating, appliances, and the kind of daily consumption that would cost a fraction of the price back home.
For the O’Driscoll residence in Tarlac City, that reality was the motivation. Not a vague interest in sustainability, but a straightforward response to bills that made no sense to absorb indefinitely.
Solaren designed a grid-tied system around the home’s actual daily load profile, specifying SMA Germany SB6.0 inverter technology paired with Trina Solar Vertex modules, monitored continuously via SMA ennexOS. The system generates consistent daytime offset with night-time export credit returning additional value through net metering.
For foreign nationals planning long-term residence in the Philippines, solar is one of the most direct ways to bring household running costs in line with expectations. The real solar energy ROI becomes clear quickly when the alternative is paying Philippine grid rates indefinitely.
