Domingo Residence
- Grid-Tied Solar Home with Full Offset
- System Size: 7.63 kWp
- Completion: 11-Oct-2023
- Hacienda Luisita, Philippines
Project Summary
A home on the fairways of Hacienda Luisita carries a certain set of expectations. For the Domingo residence, one of those expectations is now a zero electricity bill — not just while the owner is in residence, but accumulating credit through the extended periods spent away.
The system was designed around a net metering strategy from the outset. When the house sits empty, generation continues and surplus exports to the grid as credit. Those credits stack month after month, building a balance that offsets consumption entirely when the owner returns. For a homeowner spending significant time abroad in retirement, that accumulation is not a side benefit. It is the point.
SMA Germany SB6.0 inverter technology paired with Trina Solar Vertex modules, monitored via SMA ennexOS, has delivered consistent full offset since October 2023. The system is quietly doing its job on one of the most prestigious addresses in Central Luzon, with no bills, no interventions, and no surprises.
For homeowners planning semi-retirement or extended time away, residential solar ROI compounds differently when the meter runs in your favour while the house sits empty.
