Battery storage retrofits are now available (even if you already have solar)

If you’ve already got solar panels (or you’re moving into a home that has them), you don’t need to start again to get the “day + night” benefits. We’re now offering battery-only installs (retrofits) across Devon & Cornwall, so you can store your surplus solar and use it later when electricity is most expensive.

New year, new cap — and higher bills. Want more control in 2026? ☀️

What’s new?

You can now add a battery to:

Existing solar systems: (installed by us or another installer)
Homes with no battery-ready setup: (we’ll advise what needs changing, if anything)
Solar + EV homes: where you want to charge smarter and reduce grid use

Why it matters (in plain English)

Without a battery, a lot of your daytime solar gets exported. With a battery, you keep more of your own power and use it in the evening—lights, cooking, laundry, and even overnight EV top-ups depending on your setup.

Do you need to replace your inverter?

Not always. Some systems are already compatible. Others may need a small upgrade (or a different approach) depending on what you have installed. We’ll confirm this during the quote and survey.

What we’ll help you do

Choose the right battery size for your usage
Decide if you want backup power during outages (optional, but popular)
Set up smart scheduling so your battery works around your routine and tariffs
Keep everything tidy with clean install routes and clear handover docs

How it works

Install + commissioning + app setup

You start using more of your own energy, day and night
