About SolBatteryCalc

SolBatteryCalc is a free online tool that helps homeowners estimate the right size battery, inverter, and solar panel system for their home energy needs.

Simply tell us your country, monthly electricity usage, and backup duration — we calculate the recommended system size and estimated savings using local electricity tariffs and solar data.

We support 20+ countries across Africa, Asia, the Americas, and Europe, with data sourced from GlobalPetrolPrices.com and the Global Solar Atlas.

Product pricing is based on manufacturer reference pricing (EXW USD). For accurate quotes, contact a local installer.
