SunScore Rooftop Solar Calculator
Enter your bill, roof area, shade and direction for an estimated system size, yearly saving, subsidy and payback.
How SunScore works
It converts your monthly bill into units, matches them to a system size limited by your usable roof and sanctioned load, and applies generation, shade, orientation, current subsidy rules and the KERC export tariff. The result is an estimate, and the assumptions appear under it.
Questions
