How big should the solar battery be

Battery sizes are measured by their capacity to store electricity, but it’s important to consider usable capacity rather than just what the total capacity is. That’s because you don’t want to actually use a battery’s entire capacity, as this can damage it. The usable capacity is called depth of discharge (DoD), and most modern batteries.
