SolarMap.PH

your roof · payback estimate

How long until rooftop solar pays for itself in your city?

Three inputs, one number out. We use a PVGIS-derived Philippine yield baseline (~1315 kWh/kWp/yr), the current Meralco residential rate (₱12.50/kWh), and the SolarMap.PH detection survey to surface how much rooftop solar already exists in your city plus the LGU permit cost where verified. All math runs locally in your browser. Nothing about you is sent anywhere.

Picks from the 61 cities and municipalities in Meralco's franchise. Nothing sent to any server; matching runs locally.

Typical PH residential: 60-120 m².

Estimates only. Not engineering advice. Talk to a certified installer before committing.
