There are a few reasons why it makes sense to buy an energy storage system to complement your PV system: With a PV storage system, you can use your electricity generated by the photovoltaic more effectively. For example, surplus electricity produced during the day can be stored and used in the evening when less solar energy is available.
A solar battery allows you to store electricity produced by your solar panels and use it later or, in some cases, sell it back to the grid to make a few quid – but they're not cheap. Read on to see if it's worth getting a solar storage battery for your home... This is the first incarnation of this guide.
When choosing and installing a solar battery storage system, make sure your installer is signed up to the Renewable Energy Consumer code (RECC) or the Home Insultation and Energy Systems Contractor Scheme (HIES), as this means you'll be covered should you need to make a complaint or claim.
You don't need a home solar panel system to reap the benefits of batteries, but you'll get the most out of your system when you pair them together––especially if your utility doesn't pay you a lot for the excess electricity your solar panels generate and send to the grid.
