Top Solar Companies in Massachusetts

How to Evaluate Solar Companies
Why Installer Selection Matters
The company you choose determines whether you'll save $28,000-$52,000 (with ownership through loans) or just $10,000-$18,000 (with leases). Quality installers educate you on ownership benefits rather than pushing whatever makes them the most money.

Critical Questions to Ask Every Installer
About Financing & Ownership
"Do you recommend I own my system through a loan or lease it?"
Best answer: They explain loan benefits and help you own the system to capture incentives
"What incentives will I receive, and what's my net cost after all incentives?"
Should detail federal credit ($5,400-$9,900), MA state credit (up to $1,000), and SMART program income
"What happens if I sell my home before the loan is paid off?"
Owned systems add home value and transfer easily; leases complicate sales
About Equipment & Installation
"What panel brands and inverter options do you offer?"
Look for Tier 1 panels with 25-year warranties
"Will you do an in-person site assessment or rely on satellite imagery?"
In-person assessments catch issues satellite misses
"Do you use in-house crews or subcontractors?"
In-house crews typically provide better quality control
About Warranties & Service
"What warranties cover panels, inverters, and workmanship?"
Standard: 25-year panels, 10-25 year inverters, 10-year workmanship
"How do I request service if there's an issue?"
Should have clear local contact and response timeframes
"Can you provide 3-5 local references I can contact?"
Reputable installers readily provide recent references
