How this site is paid for

Can I Plug In Solar is free to use, with no sign-up.

There are no affiliate links, paid links or ads on the site today. Links to other sites go to the sources we cite (statutes and legislatures, government agencies and utilities, standards bodies and labs, researchers, news reports and the makers whose products we track) and to our own social profiles. Nobody pays for any of them.

If we add paid links

We may later link to plug-in solar kits as an affiliate, or to an installer-quote service as a paid referral. If we do:

• Every paid link has a "Paid link" label right next to it, not just a note in the footer.
• Every paid link carries rel="sponsored", so search engines know too.
• A kit is only listed once we've checked its UL 3700 certification status, and that status is shown next to it.

What is never paid

• The law answers: state law cards and state pages carry no ads and no paid links, ever.
• The calculator results: savings and payback come from the same model whether or not a link earns us anything. See how we calculate.

A paid link never changes a law answer or a calculator result.
