Why do you need a solar battery?
Heard the buzz about Tesla Powerwalls and wonder what they actually do? Here’s our overview of all PV (Photo-Voltaic) batteries for use at home.
What are they?
PV Batteries are added onto solar systems to store any unused power generated for use later in the day. Some brands of PV batteries allow you to control when your battery charges from the grid to make the most of the Economy 7 Tariff. If you don’t have solar panels installed, you can still have this installed to only be used for off-peak charging and back up.
Who can have PV batteries?
Anyone with solar systems installed can have PV batteries installed onto their existing system. The Tesla Powerwall 2 is compatible with all types of solar systems. However, bear in mind that some other brands of battery may not be compatible across all solar systems available.
What if I don’t have solar?
No problem! The Tesla Powerwall 2 allows for users without solar panels to have it installed to use only for off-peak charging using economy 7 tariff meaning cheaper electricity during the day, not just at night!
What does it cost to install a PV battery?
The cost is dependent on the system being installed, contact us today for a bespoke quotation!
One thing worth bearing in mind is that if you don’t have solar panels yet and decide to add a battery with your installation plans you can get all of it installed under the 5% VAT bracket! Saving yourself a healthy 15% in VAT. However, if they are installed after the solar panels – so added on – the rate then reverts to 20%. A huge incentive to think about a solar battery upfront as part of your renewable energy plans at home.
