Terms

By using solar.day you accept that the estimates, rankings, and recommendations we show you are guidance, not financial or technical advice. Every number is sourced and dated, and we work hard to keep them current – but they are estimates about a typical version of your home, not a survey of your actual one. Decisions about buying or installing anything are yours alone, and a proper installer quote should always come before money moves. The tool is provided 'as is', with no warranty.
