Estimate solar-system performance anywhere in the world from location, installed power, battery, consumption and total costs.
Method
01
Resolve the location to latitude and estimate the monthly solar pattern for the selected climate.
02
Calculate production, self-consumption, surplus, grid import, savings and payback.
03
Show a monthly chart and suggest practical uses for surplus production.
Your inputs
Location, installation and consumption
Edit assumptions and review the result instantly.
Latitude
Enter a latitude from −90° to 90°, or use your device location. Then choose the closest climate band.
Average monthly consumption
Total energy used during one complete average month, not per day. Find the kWh figure on your electricity bill.
Electricity purchase price
Location, installation and consumption
Contracted power
Location, installation and consumption
Fixed power charge
Monthly fixed price for each contracted kW. Solar panels do not automatically reduce this charge.
Maximum installed power
Location, installation and consumption

This is a guidance estimate by latitude and climate band, not a quote or engineering study. It does not know the exact roof geometry, shading or weather.
