All electrical components must be UL-listed and comply with the National Electrical Code and NFPA standards, with sealed calculations from a licensed professional engineer required to demonstrate compliance with wind load specifications. Warranty requirements include 25 years for solar panels, 5 years for structural and battery storage components, and 2 years for electrical components and installation workmanship.
