Clear solar numbers before you buy.

SolarWorth creates independent calculators that help homeowners understand solar costs, savings and assumptions before speaking with an installer.

Why SolarWorth exists

Solar estimates often hide important assumptions. SolarWorth shows how self-consumption, export rates, system output, electricity prices, maintenance and degradation affect the result.

What SolarWorth does not do

SolarWorth does not inspect roofs, design electrical systems, guarantee performance or replace professional quotes. Results are planning estimates only.
