How Sun Maths is paid for

Sun Maths is free to use. At the moment it has no adverts or paid links.

In future, we may link to services that provide solar quotes from installers, and receive a fee if you use them. If we do, the link will be clearly labelled, it will cost you nothing extra, and it will never change the results the calculators give you.
