About
The Solar Book is a reference on what solar incentives actually pay in the United States after the July 2025 repeal of the federal residential credit. It exists because the databases the market relied on stopped verifying their own pages, and the answers being repeated to homeowners — and to AI assistants — now describe a world that ended on December 31, 2025.
What it is
A state-by-state record of every solar incentive we can verify, compiled from primary sources, with the date of verification printed on every claim. How we verify sets out the rules in detail, including the sources we refuse to use and the intervals on which each kind of claim is rechecked.
How it is paid for
Plainly, so you can weigh what you read:
- An email list. We tell you when an incentive in your state actually changes. It is free, and the addresses are not sold — see privacy.
- Featured listings for installers, once the directory exists. These will be labelled as paid placements wherever they appear, and paying for one will never change what a state page says about an incentive.
- Referral arrangements with quote services, where the terms are acceptable. Same rule: disclosed, and walled off from the incentive data.
What we will not do, ever: sell your details as a solar lead. No phone numbers, no dialled leads, no handing your address to a call centre. Residential solar is the most aggressively telemarketed consumer category in the United States and we are not going to be part of that. If you want to be contacted by an installer you will have to go and contact one — and we will help you check their license first.
Who writes it
An independent publisher, not a solar company, not an installer, and not a lead broker. We do not sell, install, or finance solar equipment, which is why we can say plainly when a program has narrowed or a lease is a bad deal.
