Installation of a Tesla Powerwall is a big decision for a big-ticket item. But five months in and combined with our existing PV system, the benefits are there to see every day on the Tesla app. For the past three and a half summer months we have not been less than 94% self-powered – and that includes all the hot water we’ve needed for a house with four adults. And during the colder months we’ll be able to download cheap electricity overnight. No more big energy bills for us!

Would I recommend Cuberoot Energy? Yes! The job was done with the minimum of disruption and it’s worked without fuss since installation. When it comes to adding in an EV charger, we’ll be calling on Cuberoot Energy again!
