Including deep cycle lead-acid batteries, lithium ion batteries, and flow batteries. It’s important to work with a qualified installer in order to make sure the battery is sized and installed correctly for your system.
Ultimately, using a battery to power your home can help reduce your overall energy costs and provide you with more control over how you choose to generate and use energy.
What happens to solar power when batteries are full?
When batteries are full, they can no longer accept additional power from solar panels. This means that any extra solar energy produced will be wasted. To avoid this, many solar power systems use a process called “load shedding” to reduce their output when the batteries are full.
This involves redirecting the excess energy produced by the solar panels to another load, such as a hot water heater, pool heating, or another appliance. This allows the system to continue using the solar energy without overflowing the batteries.
Additionally, some systems may be set up to divert any additional solar energy to the grid, allowing consumers to take advantage of net metering and sell the excess energy to their utility company at a favorable rate.
