Solar calculator for Philippine homes
A useful solar calculator should help you form better questions before requesting proposals. It should not pretend to replace a site survey, electrical design, structural review, or utility approval.
Planning guidance only
Verify the site, equipment, permits, utility rules, and written proposal before spending.
Start with your electricity use
Use the kWh shown on recent bills whenever possible. A peso bill can be converted into a starting estimate, but tariffs and non-energy charges vary, so the bill’s kWh figure is more reliable.
Daytime consumption matters because energy used while the panels are producing is normally the easiest solar energy to use directly.
Collect 6–12 recent bills.
Note daytime loads such as cooling, pumps, refrigeration, and work-from-home equipment.
Record whether brownout backup is a priority.
Treat the result as a planning range
Roof geometry, shade, weather, inverter selection, export arrangements, wiring, and equipment losses can move the final recommendation.
Run the calculator, save the assumptions, then ask installers to explain why their proposed capacity differs from your starting estimate.
Mga inilagay that improve isang Pilipino tantiya
Ang strongest inilagay ay buwanang kWh mula sa ang singil, followed by daytime-use share, lawak ng bubong, lilim, at whether reserbang kuryente matters. ISANG peso-lamang singil tantiya ay useful para sa starting, ngunit it maaaring maging distorted by tariff changes at charges that solar does hindi alisin.
Use isang mababa, expected, at mataas case instead ng treating one resulta as guaranteed. Ang kalkulador dapat help you prepare isang realistic saklaw para sa isang tagapagkabit discussion, hindi create isang pinal sistema disenyo.
Replace singil-nagmula kWh na may ang aktuwal kWh printed on ang singil.
Separate daytime consumption mula sa evening consumption.
Tala major future mga gamit ng kuryente such as isa pang air-conditioner, pump, o electric vehicle.
Confirm mga sukat ng bubong at lilim during isang lugar visit.
