Savings Calculator in United States (2026)

We cover 276 locations across 6 regions of United States. Electricity prices in our dataset range from $0.1277 to $0.3361 per kWh depending on region — a spread of 163%, which is why solar savings calculators are worth materially different amounts in different parts of the country. Roof area is measured in square feet here. Every calculator below is preloaded with that location’s electricity rate and measurement units, so the payback figure reflects local conditions rather than a national average.
