Before you sign anything
Smart instinct. A rooftop solar contract runs 20 to 25 years, and most people get one quote, one pitch, and one evening to decide. Asking for a second opinion is not rude. It is exactly what you would do with a surgery, a used car, or a new roof.
The checklist
The price of advice
Some services charge around 50 dollars to review a single solar quote. Fair enough as a business, but most of what they check, you can check yourself in about two minutes. Our checker computes your price per watt, flags the financing and ownership traps, and tells you exactly what to ask the rep next. It runs entirely in your browser: no account, no callback, no email, and nothing you type is sent anywhere.
Go one level deeper
Your city and your utility set requirements that shape the whole project: permits, interconnection policies, and whether your electrical panel really needs that upgrade on the quote. We compiled them into a free reference: solar permit requirements by state and utility rules by state. And if you work in solar yourself, the Installer Toolset has the load calculator and busbar checks the pros run.
