What role do batteries play in a solar installation?

Batteries play an important role in a solar installation because they allow for energy storage and usage when the sun is not shining, such as during the night or on cloudy days.

Solar panels generate DC electricity when exposed to sunlight, which can be converted to AC electricity for use in homes and businesses or fed back into the grid. However, without batteries, any excess energy that is generated during the day but not used immediately is lost.

By adding batteries to a solar installation, excess energy can be stored for later use, providing a reliable and consistent source of electricity. This is particularly useful for off-grid or remote areas that do not have access to a reliable power grid, or for homes or businesses that want to reduce their reliance on the grid or have backup power in case of outages.

Batteries can also help reduce energy costs by allowing homeowners and businesses to use stored energy during peak demand periods when electricity rates are highest. Additionally, batteries can extend the lifespan of solar panels by reducing the stress on them from constant fluctuation in energy generation and usage.
