Key takeaways
How long a solar battery lasts depends on three factors: how big the battery is, how much electricity you use, and how quickly you can recharge the battery
Factor one: how big is your battery?
There are two main components to understanding how large a battery is: stored capacity and power. Stored capacity characterizes how much electricity the battery can hold at once, and is expressed in kilowatt-hours (kWh).
Factor two: how much electricity are you using?
Different appliances in your home require different amounts of power to use, and run for different amounts of time. For instance, a standard CFL light bulb requires 12 Watts (W) of power, a microwave oven might use 1,000 W, and a central AC unit might use 5,000 W ( Note: 1 kilowatt, or kW, equals 1,000 W ).
Factor three: how quickly is your battery recharged?
If you have standalone storage and the grid goes down, then as soon as you deplete your battery that’s it. Your backup power source is gone until the grid is restored. If you pair a battery with solar, however, your solar panels can replenish your battery’s charge when the sun is shining.
