You can't just pick the cheapest bid and hope for the best. Solar is a long-term investment, and a bad install will cost you more in headaches than you saved upfront. Here's what you actually need to ask before signing anything.
Licensing & Insurance Questions
Ask for their state contractor license number. Look it up yourself — don't take their word for it. Every state has a database. Also demand proof of general liability and workers' comp. If they show up with neither and someone gets hurt on your roof, that's your problem, not theirs.
Experience & References Questions
How many residential installs have they done? Not commercial, not their cousin's garage. Ask for three recent local customers you can call. If they dodge or give you a buddy's number, walk. Also ask who's actually doing the work — some companies sub everything out, and the crew on your roof might have zero training.
Pricing & Timeline Questions
Get a line-item quote, not a single lump sum. You want to see equipment costs, labor, permits, and any fees broken out. Ask about the timeline in writing — start date, completion date, and what happens if they run late. Weather delays are fine; 'we're waiting on parts' for three months is not.
Contract Questions
Read the whole thing before you sign. Look for cancellation terms, warranty details, and who handles permit delays. Make sure the warranty covers both the panels and the labor. If the contract says 'subject to change' without your approval, strike that line. Don't let them rush you.
