Solar installation contractors design, permit, and mount new photovoltaic systems, handle utility interconnection, and provide ongoing warranty support. For homeowners, the key questions are NABCEP certification on the crew, a 10-year-plus workmanship warranty, and a written production estimate modeled in PVWatts or Aurora. For commercial buyers, look for OSHA 30 compliance and documented experience with projects of similar size.

In New York, solar installation contractors are typically licensed at the state level for electrical or general construction work, and the most-cited credentials homeowners check on this page are NABCEP certification, manufacturer training (Tesla, Enphase, SolarEdge), and verified workers' compensation coverage. Confirm SUNation Energy Corporate\'s state contractor license number with your New York licensing board, verify any NABCEP credentials at nabcep.org, and request proof of general liability and workers\' compensation insurance certificates that name your project address before signing a contract. For larger projects, ask for two or three references from recently completed installs of similar size and call them about quality, schedule, and warranty service experience.
