Key qualifications to verify
Start by confirming that the installer holds a valid Massachusetts contractor's license and is certified by the North American Board of Certified Energy Practitioners (NABCEP). These credentials prove the company meets state safety standards and has undergone industry‑wide training. Ask for proof of insurance—both general liability and workers' compensation—to protect you from potential claims during the installation.

Understanding system design and sizing
A competent installer will conduct a site assessment that includes roof orientation, shading analysis, and structural capacity. The resulting design should specify panel type, inverter size, and mounting system tailored to your home's energy profile. Look for a written proposal that details expected production (kWh per year) and how that aligns with your historic electricity usage.
Financial considerations and incentives
Peabody homeowners can tap into the Massachusetts Solar Renewable Energy Certificate (SREC) program, federal Investment Tax Credit (ITC), and potential utility rebates. A transparent installer will break down the total project cost, financing options, and expected payback period. Beware of unusually low bids that omit permitting fees or long‑term maintenance.
Warranty and post‑installation support
Strong warranties cover both equipment (typically 20‑25 years for panels) and workmanship (usually 10 years). Verify that the installer partners with reputable manufacturers and that warranty claims are handled directly by the installer rather than a third party. Ongoing monitoring services can alert you to performance drops and schedule maintenance before issues become costly.
Local reputation and references
Check online reviews, Better Business Bureau ratings, and ask the installer for recent client references in Peabody or neighboring towns. Homeowners who have completed installations can speak to the installer's punctuality, communication style, and how well the system meets promised output.
