Weather and Durability
Snow - Each panel has a smooth glass surface, letting snow slide off. Any residual snow that sticks will melt away as the panels produce power and heat.
Wind - The mounting systems are rated 100mph+ winds and are secured into your building.
Hail - Solar panels are built to withstand 1inch iceballs at 50mph, and will easily hold up against hail.
Tesla Energy panels are backed by a 25-year product and labor warranty.
