Essential Qualifications
Verify C-10 electrical and C-46 solar licenses, NABCEP certification, proper insurance, and bonding. Check BBB rating, online reviews, and request references from similar projects.
Experience Evaluation
Look for 5+ years in business, 50+ commercial installations, and experience with your building type. Verify manufacturer certifications and utility approved vendor status.
Warranty Comparison
Ensure 10+ year workmanship warranty, 25-year panel warranty, and comprehensive O&M options. Verify company financial stability to honor long-term warranties.
Red Flags
Avoid high-pressure sales, unusually low bids, upfront payment requirements, and contractors without proper licensing. Be wary of companies without local presence or track record.
