How big a battery do you need for home solar power
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. The size of the solar battery you need will depend on the size of your home — specifically, how many bedrooms it has. To work out what size. Generally speaking it is better to buy an oversized solar battery, but only as long as your solar panel system is big enough. Otherwise you'll want a smaller storage battery, because there's little point paying more for a large battery. You can charge an electric car with a storage battery, but it's typically not worth it because you'll almost certainly need to tap into the grid to finish charging. You'll need either a battery with a very large capacity, or multiple. Yes, but there are caveats. You'll struggle to fill multiple batteries without a large solar panel system.
