10 kW solar system with a battery — The ideal size solar battery for a 10 kWp solar panel system is 20–21 kW, as it’ll be able to make sure the battery is properly charged throughout the day. Which solar products are you interested in? What size battery do I need to go off-grid?
When heating and cooling are included in the backup load, a home needs a larger solar system with 30 kWh of storage (2-3 lithium-ion batteries) to meet 96% of the electrical load. The exact number of batteries you need depends largely on your energy goals.
This capacity will allow the solar system to efficiently charge it. 5 kW solar system with a battery — If your home has a 5 kWp solar system, you’ll want a battery capacity of between 9.5–10 kW. Keep in mind that you’ll want to use most of the electricity you generate during the day for charging your battery
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 battery you’ll need, you can start by calculating your electricity usage. Look at either your smart meter or your monthly energy bill, which will tell you how much you use on average.
This means, for a 6kW solar array with a 48V battery bank, you'd need roughly 1000Ah at 48V. Daily energy needs: On r/solarenergy, a user pondering the impact of a 6.4 kWh solar system against 20-25 kWh daily consumption felt that 13-16 kWh battery storage would help dodge peak PG&E rates. The gist is to estimate your consumption first.
If you use 8 kilowatt hours (kWh) per day, then you’ll need a battery with a capacity of at least 8 kilowatts (kW) to provide all of your energy needs during the day. Keep in mind that you won’t always be at home though, so you could get away with a smaller battery. What size solar battery for solar panels?
