Questions about storage?
What battery storage options are available?
For a home battery to be installed alongside an Egg solar PV system we recommend the SolarEdge Battery Bank as it integrates nicely with our standard invertor system to provide optimum power output. For standalone battery installations the Tesla Powerwall is a great option. Both have plenty of energy storage capacity, to help most homes collect any excess solar they generate and then use it later when they need it (even when the sun has gone down).
I’m thinking of getting solar panels, should I get a battery too?
A home battery is a great way to ensure that you store any excess energy you generate from your solar panels to use later in the day when you need it – for example, in the evening when the sun has gone down. Especially if you’re not using as much energy during the day when your solar panels are generating energy, a battery makes sure you don’t lose out on that hard earned green energy – as without a battery, if you don’t use your solar energy it gets lost to the electricity grid. This means you’d instead have to rely on more expensive, less green energy from energy suppliers instead.
Also, installing a battery at the same time as your new solar panels means your battery qualifies for the same 5% VAT rate as solar (instead of 20%) – so getting them together gives you an extra smart saving!
How can I monitor how much energy my battery is storing?
Both of our battery options, SolarEdge and Tesla Powerwall come with an app which allows you to monitor the performance of your solar and battery system, including a live view of how power is moving between your solar panels, your battery, and your home.
Should I get a battery if I don’t have solar panels?
You absolutely can – but you should consider the benefit of doing so, which is significantly less if you don’t have solar panels. It is possible to sign up to a “time of use” tariff from your energy supplier (e.g. Economy 7) which would allow you to charge up with cheaper electricity overnight to use during the day for a modest saving, but with energy prices constantly changing we advise you give it some real thought first.
