The 7.63 kWp Linda Gray Residence installation in Luna, La Union is a straightforward grid-tied residential system, but its coastal location makes equipment selection particularly important. The property is relatively close to the sea and beach, where salt exposure can accelerate corrosion. Solaren therefore selected equipment suited to the demanding coastal environment rather than treating the project as an ordinary inland residential installation.

The system is fully net-metered, with the local distribution utility providing good cooperation during the approval process. Household demand is conventional, including air-conditioning, pumps and normal domestic loads, and the solar system has performed in line with its forecast yield since commissioning in 2024. The original SMA inverter and Sunova bifacial modules remain in service and have operated flawlessly.

The owner is now considering battery storage. Rather than remove the existing SMA inverter, Solaren’s proposed approach is to add a hybrid inverter that can work with the existing grid-tied equipment. This would preserve the original investment while adding storage and backup capability, demonstrating how a conventional net-metered solar system can be upgraded later without unnecessarily replacing equipment that is still performing well.
