Common questions
Is a watt calculator the same as a kWh calculator?
Watts measure power at a moment; kWh measures energy over time. This appliance tool provides both connected running watts and daily energy. For a solar calculator, kWh demand helps size generation, while simultaneous power and startup surges determine inverter requirements.
Can I include lights when planning solar power?
Yes. Add the number of lights, electrical watts per light and hours of use to your appliance list. For a standalone solar light with its own panel and battery, this estimates only the lamp energy demand; it does not verify the built-in battery, charge controller or manufacturer runtime claims.

Abans d’utilitzar el resultat
Nameplate wattages are starting points. Refrigerators and inverter ACs cycle or vary their power: use measured average energy or an appropriate duty cycle. Starting surges are not included in connected load.
How should I enter an air conditioner?
Use its electrical input watts, not cooling capacity or tonnage. Adjust duty cycle for actual operation.
