About
We do the boring math so a salesperson can't do it for you
Solar quotes are designed to be confusing. WattBarn exists to make them legible: what a system should cost, what it should save, and how long payback really takes in your state.
How we research
Every guide explains how a solar quote is built and runs the payback math in the open, so you can swap in your own rate, roof and system size. We hold no bid database, we collect no installer quotes, and we run no surveys. Figures are illustrative and labelled, and rates and incentives point back to your own utility and the agency that sets them. We are not an installer, we sell no leads, and no one in the trade owns us.
How we make money
At the time of writing this site carries no affiliate links and no advertising. No link earns a commission and no company pays for coverage. If that ever changes, the disclosure page will say so first and any paid link will be marked where it appears.
