Roxas Residence
- Provincial Grid-Tied Solar Home
- System Size: 24.50 kWp
- Completion: 6-Oct-2025
- Paniqui, Tarlac, Philippines
Project Summary
When a new home is designed from the ground up, every system decision is an opportunity to do things properly rather than retrofit them later. For this premium residence in Paniqui, Tarlac, solar was integrated into the construction from the planning stage, conduit runs, mounting structures, electrical infrastructure, and inverter placement all designed in before a single wall was finished.
That level of pre-planning produces results that a standard retrofit cannot match. Cable runs are shorter, the installation is cleaner, and the system integrates with the home’s electrical architecture rather than working around it. The result is both more efficient and more aesthetically considered than anything added after the fact.
SMA Germany SB6.0 inverter technology paired with Sunova Solar bifacial modules, monitored via SMA ennexOS, delivers strong daytime generation across the full roof area, with net metering returning surplus to the grid under a fully compliant interconnection.
For anyone planning a new build, this project makes the case plainly. Solar designed in from the start costs less, performs better, and looks far cleaner than solar added as an afterthought.
