Choosing an installer, spotting red flags, reading warranties and budgeting for maintenance.
A solar system is a 25-year relationship with the company that installs it. Equipment matters, but workmanship, paperwork and who answers the phone in year eight matter just as much. This section covers how to vet installers, how to read a quote critically, what warranties actually promise and what ongoing care costs.
The guides avoid ranking companies. Instead they give you criteria you can verify yourself: state license checks, certifications such as NABCEP, written scope of work, warranty terms and the structure of the contract. A quote checklist pulls those points into one place you can print.
If you are in the middle of comparing proposals, read the red-flags guide first, then the contractor selection guide. If your system is already on the roof, jump to the maintenance and lifespan guides.
