Put this solar calculator on your site

Free, no signup, no tracking of your readers. They type an address, they get their own roof measured from Google's aerial imagery. Copy the code and it works.

The code

That is the whole thing. It is responsive, it works on mobile, and it does not load any advertising inside the frame.

What it costs you

Nothing, and there is no catch worth hiding. The calculator carries a small credit line linking back here, and that link is rel="nofollow" on purpose. Google treats followed links inside distributed widgets as an automated link scheme, so a followed link would be bad for both of us. If you would rather remove the credit entirely, do that instead of making the link followed.

Who this is actually for

• Solar and energy blogs that write about whether solar is worth it and want readers to check their own roof without leaving the article.
• Installers who want a genuine estimate tool on the site rather than a lead form dressed up as a calculator.
• Local news and community sites covering energy costs, where a "check your own address" tool makes an abstract story concrete.
• Property and moving sites, where roof solar potential is a real consideration that most listings never mention.

What it actually does

The same thing this site does. It calls Google's Solar API for the specific building at that address, reads its usable roof area, how many panels physically fit and how many hours of usable sunlight it gets after shading, then applies the economics: 400W panels, a 15% system loss, installed cost per watt, and the local electricity rate. It recommends a sensible system size rather than the maximum that fits, because filling a roof usually returns less.

It does not collect email addresses, it does not store the address typed into it, and it does not pass anything to installers.
