Frequently asked questions about solar, batteries and EV charging

Home charging on an overnight time-of-use tariff is usually much cheaper than rapid public charging. The exact cost per mile depends on your tariff and your car, so we show the assumptions in your quotation rather than quoting a standard figure.

A battery lets you use your solar generation in the evening instead of exporting it cheaply. It also lets you buy electricity at an overnight rate and use it during the day, which gets more value from the whole system.

Yes. On sunny days surplus solar can charge the car directly. A battery helps by storing excess generation for the car to draw on later, so less is exported for a low rate.

SP Energy Networks covers central and southern Scotland. SSEN covers the north, Highlands and Islands. Your postcode decides which one applies to your installation.

A typical solar and battery installation takes one to two days on site. The survey and network approval happen beforehand. Charge point installation is subject to survey and network operator approval.

Interest-free credit up to £30,000, subject to status. Your quotation sets out the full price, and the finance option alongside it if you want it.

We install through MCS-certified partners. Ask whether your guarantee is insurance-backed and whether it survives if the company ceases trading. The installer named on your MCS certificate is the company doing the work.

Charging a car at home adds to your electricity use. That extra demand is why pairing solar and a battery with an overnight tariff matters: more of the house and car use is covered by cheaper or self-generated electricity.
