Home is not just an alarm system. The safety guidelines of any state mandate residential and commercial units to have proper emergency exit signs for the benefit of their team members and visitors. Traditional incandescent LED exit signs used to consume a lot of energy and came up with hefty utility bills at the end of the month. New generation LED exit signs with battery backup reduce utility bills and deliver uniform brightness even when there is a power outrage. The battery backup can last from 90 minutes to 120 minutes.
With solar energy, you have power even when the grid doesn’t.
This is especially helpful when your panels are connected to a Tesla Solar Powerwall, which is a backup battery that easily and economically stores excess energy for when you need it most.
