Completed Solar Installations

The installs shown here all run a Solis or Deye hybrid inverter, 620–625W bifacial panels and a LiFePO4 battery. That is what we build for homes.

The reason is what happens at 7pm and what happens during a brownout. A grid-tie system exports surplus to Meralco during the day and buys it back at night at a worse rate, and it shuts down entirely when the grid drops. A hybrid stores the surplus instead, so the evening runs off the battery and an outage is something you notice from the neighbours rather than from your own lights.

Read across the specs and the arrays cluster while the batteries do not. Two homes on the same 6 kW Solis and a 6.2 kWp array — one in Bulacan, one in Parañaque — each took 16 kWh of storage. A home in Marilao with a larger 7.4 kWp array took 10 kWh. Tagaytay pairs a 10 kW inverter and 8.7 kWp with 10 kWh.

That is deliberate, not inconsistency. The panels answer how much energy you generate; the battery answers how much of it you use after dark. A household that is out all day and runs aircon at night needs more storage than one with an identical bill spread across the afternoon. Sizing the two together is how a system ends up either short on backup or carrying battery capacity nobody ever draws on — and the battery is the expensive half.

Several of these run an array smaller than the inverter rating: 9.92 kWp on a 12 kW inverter, 8.7 kWp on a 10 kW. That gap is not an oversight or an upsell.

It is what lets a system take more panels later without replacing the inverter. Households grow — another aircon, an EV, a child working from home — and adding panels to an inverter with room is a modest job, while swapping the inverter is most of the cost of starting over.

Most of the homes shown here are two or three storeys, and the locations run from Marilao and Bulacan through Valenzuela and Parañaque out to Tagaytay City. Height and distance both matter on a quote: longer DC runs, more access planning, and a roof that has to be assessed before anything is promised about panel count.

That is why the site assessment comes before the number. What a roof can carry and where the array can actually sit are things you establish on the roof, not from a bill.
