For a 10 kW solar system, the ideal size solar battery is 20–21 kW. This ensures the battery is properly charged throughout the day.
How much battery capacity is needed for a 5 kWp solar system?
If your home has a 5 kWp solar system, you’ll want a battery capacity of between 9.5–10 kW. This capacity will allow the solar system to efficiently charge it. Keep in mind that you’ll want to use most of the electricity you generate during the day for charging your battery.
How many 300W solar panels do I Need?
If you have 6 x 100ah batteries and 3600 available watts, you need five 300W solar panels to replenish it and keep the solar system running. Five 300W solar panels can give you 1500 watts an hour. Of course this is assuming the weather is ideal, so the total may be a bit lower. If it is summer and 6 to 7 sun hours are available, 5 panels will do.
