10kW Solar System Philippines: Price, Panels, Output

A 10kW grid-tied solar system fits a big home or small business with a ₱15,000-17,000/month electric bill. It needs about 20 panels and 70-90 sqm of roof space, costs roughly ₱500,000-750,000 installed, and produces around 1,200 kWh a month. A well-matched 10kW system typically cuts the bill by 40-80%, and for businesses running equipment through the day, payback tends to land around 3-5 years.

10kW system at a glance

Is 10kW a residential size or a commercial one?

Both, depending on the property. A large single-family home with a high bill — multiple aircon units, a pool pump, an electric water heater — can land here just from household usage. So can a small business: a sari-sari store with refrigeration, a small restaurant, a laundromat, or an office running equipment through business hours. See our solar for small business guide if the property is commercial rather than residential, since financing, depreciation, and usage patterns differ from a home installation.

How does 10kW compare to sizing down?

If your bill runs ₱12,000-13,500, an 8kW system is usually the better match — see our 8kW guide. Sizing up to 10kW on a smaller bill means more of the system’s output gets exported at the lower net metering rate instead of offsetting full-price grid power directly.

Why does a business get faster payback than a household at the same size?

Because a business running equipment, refrigeration, or lighting through standard operating hours uses a much bigger share of its solar output directly, at full retail value, instead of exporting it through net metering at roughly ₱5-7/kWh. A household with the same size system but an empty house until evening exports more of its output at that discounted rate, stretching out payback. See our payback period guide for how usage timing changes the math.

What does net metering look like at 10kW?

Straightforward. Both residential and non-residential net metering cover systems at this size without special tiers — the residential cap stays at 100kW under RA 9513, well above 10kW either way. Some reports say a 2026 DOE circular raised the non-residential cap toward 1MW, but that isn’t consistently confirmed across DOE, ERC, and mainstream reporting, so a commercial customer sizing a system near or above 100kW should confirm the current limit with their distribution utility. None of that affects a 10kW system, which is comfortably within any version of the cap. Your installer typically handles the application; see how to apply for net metering for what that process involves.

Does the price hold up against smaller systems on a per-kW basis?

Roughly, yes, with a modest improvement. A 10kW system’s ₱500,000-750,000 works out to about ₱50,000-75,000/kW, similar to an 8kW system’s range, since labor and permit costs spread across more panels but equipment costs (inverter, mounting, wiring) scale close to linearly. See our price breakdown guide for the full cost split.
