Home Battery Storage
Store excess solar energy for evening use. Major brands including Tesla Powerwall, GivEnergy, and Fox ESS.
Without battery storage, a typical home exports around 50% of the solar energy its panels generate because generation peaks at midday when most people are out. Adding a battery shifts that surplus to evenings and mornings, pushing self-consumption from roughly 30% to 70-80%. On a time-of-use tariff like Octopus Agile, a battery also charges from the grid overnight at off-peak rates, further reducing bills. For most Swindon households with an existing solar installation, a battery pays back in 7-10 years and runs for 15+.

Your final price depends on battery size, whether you already have a hybrid inverter, and whether the system is AC or DC coupled. Retrofitting to an older solar setup can add a little for extra wiring or a new inverter. We confirm everything on a free survey before you commit.
