Solar batteries allow you to continue powering your home with renewable solar energy during the evening and at night when the solar panels aren’t able to generate energy.
Solar panels convert solar energy into usable electricity and, more often than not, they’re producing more electricity than can be used.
Without a solar battery, this excess is often wasted.
How do solar batteries work?
Solar panels are fitted onto a roof or exterior wall where they can be exposed to the most sunlight. Each panel includes solar cells which convert the sun’s energy into DC electricity which is then converted to AC electricity by an inverter. This can then be used to power your home.
Whatever you don’t use is wasted. This means that you can only use solar energy as and when it is available, i.e. when the sun is shining. However, this is not the case if you install a solar battery…
Solar battery storage: What you should consider
A solar battery is not a simple ‘install and leave’ unit. It needs regular monitoring and maintenance to keep it working both efficiently and safely.
This includes keeping it charged at an optimum level, carrying out regular power ‘boosts’ and gassing as well as ensuring it is stored at a correct temperature and protected from the weather.
Solar batteries do not last as long as solar panels. Currently, a high quality solar battery will last for around 10-15 years, but this is dependant on how much you use it and ensuring it is maintained correctly.
A battery can cost up to £2,000 (not including installation) so it is a significant expense to consider.
