Solar panels generate electricity from the sun. This direct current (DC) electricity flows through an inverter to generate alternating current (AC) electricity. The AC electricity powers your home appliances. Extra electricity not used by your appliances charges your batteries. When the sun goes down, your appliances are powered by the …

How does storage help us balance the grid? Energy storage allows us to move energy through time, capturing it when we have too much and saving it for when we don''t have enough. When we have excess electricity, perhaps on a really windy day, we don''t want the extra energy to go to waste. If we can store the electricity to use later, when ...
