How Solar Works How Storage Works

Generally, solar panels collect sunlight and turn it into electricity. The DC signals are fed into an inverter, which converts the DC into grid-compatible AC power (which is what you use in your home). Various switch boxes are included for safety reasons, and the whole thing is connected via wires and conduit.

Solar System Day 
Solar System Night 

Your system will power your home during the day and send excess energy to the battery to be used at night. Unlike solar-only systems, your system will now continue producing and storing energy during a power outage when the electric grid is down so you can keep your most needed lights and appliances on.
