Before You Sign With NRG Clean Energy
- California license: ask for the license number and look it up on the CSLB site; solar work needs a C-46, C-10 or B license.
- Reviews and contact details: call (888) 650-4750 or see NRG Clean Energy on Google Maps, where recent reviews tell you more than any ranking.
- Quotes: get at least three, and compare price per watt, equipment brands and the workmanship warranty — not just the monthly payment.
