It depends on your home's current energy use. Solar panels are usually the first step for homes with suitable roofs, as they reduce electricity costs directly. Adding a battery improves self-consumption by storing daytime generation for use in the evening, so many homes start with panels and add storage later.

Your panels generate the most electricity in the middle of the day, often more than you use at the time. A battery stores that surplus instead of exporting it, then releases it in the evening and overnight — so you rely far less on the grid.

Yes. With a compatible smart EV charger, your car can charge from surplus solar generated during the day, cutting your charging costs significantly. Pairing solar with a battery lets you store daytime energy to charge in the evening too.

Solar panels typically cost £5,000–£9,000 for a domestic system, and adding a battery generally adds £2,000–£5,000 depending on capacity. Use our free estimate tool to get a personalised quote for your home.
