Because retail rates are high, payback periods are often attractive even without a subsidy — commonly in the mid-single-digit years.
| Currency | Philippine pesos (PHP) |
|---|---|
| Typical electricity rate | ₱ 12 per kWh |
| Installed cost | ≈ ₱ 130 per watt |
| Peak sun hours | ≈ 4.8 hours/day |
| Export / buyback | ≈ ₱ 4 per kWh |
Indicative 2026 starting points — every figure is editable in the calculator, and results depend on your own bill, roof and installer quotes.
A typical 5 kW system in Philippines
At around ₱ 130 per watt, a 5 kW rooftop system costs roughly ₱ 650,000 and produces about 6,833 kWh in its first year at Philippines's 4.8 peak sun hours a day. Your real numbers depend on your roof, shading, panel choice and how much power you use during the day — run your own figures in the calculator to see your exact payback, net savings and ROI.
How the solar calculator works
- Your setup. Philippines and Philippine pesos are pre-selected, with local electricity rate, install cost and sun hours filled in. Enter your monthly bill, or size the system from your appliances.
- Your roof. Search your address or tap “use my location”, then draw your roof on the satellite map — or just type its area. We check the system fits and read local sun hours from NASA data.
- Your results. Instantly see your payback period, net savings, ROI, system size, year-1 production and lifetime CO₂ offset — compare cash vs. a loan, and download a PDF report.
Common questions — solar in Philippines
How many solar panels do I need in Philippines?
It depends on your electricity use, roof space and local sun hours (about 4.8 peak sun hours/day here). A 5 kW system of high-wattage panels is a common starting point for a home — enter your bill or appliances and the calculator gives your exact panel count and system size.
Does Philippines have net metering?
Yes. Net metering under the Renewable Energy Act lets residential systems up to 100 kW export surplus to distribution utilities (Meralco and others) for bill credits, subject to their application process.
Are there solar subsidies or incentives in Philippines?
There is no broad national cash subsidy for residential rooftop; the economics rest on the country's high retail tariff plus net-metering credits.
How much does a solar system cost in the Philippines?
A typical 5 kW rooftop system costs roughly ₱ 650,000 at about ₱ 130 per watt installed. Adding batteries for outages increases that — the calculator prices your exact setup.
