The panels must generate enough electricity to both power immediate needs and charge the batteries for later use. A common sizing rule suggests that battery capacity should roughly match daily solar production. For example, a 5kW solar array producing about 20kWh daily pairs well with a 10-20kWh battery system.
Let’s dive into numbers! Battery usage is highly dependent on system type: The number of batteries needed varies considerably based on whether the solar system is completely off-grid, a hybrid system connected to the grid with battery backup, or a standard grid-tied system seeking backup solutions.
The number of solar panels you need depends on battery size, sunlight availability, and system efficiency. For a 12V 100Ah lithium battery, around 400W of solar panels is ideal. Larger systems like 24V, 48V, or 20kWh setups require proportionally more panels.
Most experts recommend sizing batteries to cover 1-3 days of critical load usage. This provides a reasonable balance between cost and reliability. Solar panels and batteries work as partners in a complete energy system. The panels must generate enough electricity to both power immediate needs and charge the batteries for later use.
