How Much Solar Do I Need for My Battery Bank?

Table of Contents

While lithium batteries are a great way to store power, adding renewable energy generation to your off-grid system will increase your independence. Solar panels allow you to harness the power of the sun to recharge your batteries and keep your electronics and appliances up and running. In order to have the most effective power system, it’s crucial to ensure you have the proper number of solar panels for the size of your battery bank.

What Solar Capacity is Required for My Battery Bank?

Although solar power is a great way to take advantage of renewable energy and generate electricity, it only works when the sun is shining. If an off-grid system relies on solar panels alone, there will be no power available at night or on cloudy days. Utilizing an energy storage system is the best way to collect excess energy when the sun is shining and use it to power your electronics when the sun isn’t shining.

LiFePO4 batteries are an extremely powerful and efficient way to store solar energy for later use. To determine the number of amp hours of batteries you will need, you will need to perform an energy audit. This entails evaluating your system loads, various appliances, and electronics, how much power they use, and how long you want to run them. Based on these calculations, you can determine the number of amp-hours of batteries required to keep up with your power needs.

The Battle Born battery bank calculator offers a simple way to input all of your desired system loads and receive a recommendation for the number of amp hours your battery bank should be. Then, you can use this number to determine how much solar your system needs. To ensure proper powering of your system, we recommend 200W of solar panels for every 100Ah of battery capacity.
