Energy Storage Solutions

A battery isn't always worth it, but when it is, it can make a big difference. We'll be honest about whether one makes sense for your setup.

When Does a Battery Make Sense?

Good Reasons to Add a Battery

You're out during the day and can't use solar as it's generated
You're on a smart tariff: charge overnight at the cheap rate, use it at peak times
You want backup power for outages (useful in rural Devon/Cornwall)

The Financial Picture

You use more of your own solar generation instead of exporting it
With a time-of-use tariff, a battery can charge overnight at the cheap rate as well as from your panels. What that's worth depends on your tariff, your battery size and when you use power, so we work it out for your property at survey.
Most systems are expandable. Start with what makes sense now, add more later
