How does a solar battery work?
A solar battery is a device that stores excess solar energy so that it can be used at a later time.
It works by using a photovoltaic (PV) panel to convert sunlight into electricity. This electricity is then stored in the battery for later use.
When the solar panels produce more electricity than is being used by the home, the excess energy is sent to the solar battery for storage. The battery stores the excess energy in the form of chemical energy. When the solar panels are not producing enough energy, such as at night or on cloudy days, the battery can release the stored energy back into the home to be used as electricity.
Overall, a solar battery is a useful device that allows homeowners to store excess solar energy and use it when needed, helping to maximise the use of their solar panels and reduce their reliance on traditional grid energy.
During the day:
The solar panel system generates solar electricity.
The battery storage system will check if all the generation is being used to power your lights and appliances.
If you’re not using all the electricity, any surplus energy is used to charge the battery.
Once the battery is fully charged, if there is still more solar electricity being generated, this will be exported to the grid.Excess energy can be sold back to the grid under the Smart Export Guarantee (SEG)
In the evening or at times of low solar generation:
The solar panels have a reduced output.
If your demand is greater than the electricity generated from your solar panels, it can be diverted from your battery. This ensures that you are making full use of the solar power that you have captured.
