Planning a home solar system starts with understanding how much energy your appliances use and when you need it. These calculators help Philippine households compare battery runtime, panel quantity, inverter demand, backup storage and electricity costs using editable assumptions.
- Battery runtime: start with a battery and AC load to estimate operating time.
- Solar panel size: start with daily kWh to estimate array size and panel count.
- Inverter size: list simultaneous running loads and startup requirements.
- Battery size: start with backup energy demand to estimate nominal storage and Ah.
- Electricity cost: enter appliance usage and your own billed PHP/kWh rate.
