Battery Sizes and Pricing

What size battery do I need?

The size of battery storage that’ll be beneficial to you will be dependent on:

  • Your households daily energy usage
  • How much excess energy your solar power system generates and;
  • How much independence you want from the grid

As an example, if you are using 6kWh of the 16kWh your solar power system is generating during the day and you expect to use at least 10kWh of power at night (common for a household with 9-5 pm workers) a 10kWh battery will store this excess power for you to be able to use at night, once your solar power system is no longer generating energy from the sun. This means unless you go over that 10kWh of power you won’t need to use any additional energy from the grid.

Before deciding which battery size is right for you, you should breakdown your daily power usage and how much electricity your solar power system is generating. You can do this with your power bill or a monitoring device.

From there you can calculate how much power you use and the excess you can store.
