How much does solar battery storage cost in Devon in 2025?

Expect to pay £3,500–£8,500 depending on battery size and brand.

How long do solar batteries last?

Most batteries last 10–15 years, and many come with a 10-year warranty.

Do I need solar panels to benefit from a battery?

No — some Devon homeowners install batteries alone to take advantage of cheap overnight tariffs.

What is MCS and why does it matter?

MCS is the UK quality mark for small-scale renewables. It assures product and installation standards and unlocks benefits such as Smart Export Guarantee (SEG) payments for solar.

When is Cole Energy’s MCS assessment?

Our MCS assessment is booked for 31 October 2025.

From when will Cole Energy’s solar installs be MCS-certified?

Installations commissioned from November 2025 onward will be MCS-certified.

Will MCS certification make my solar system eligible for SEG?

Yes. With MCS certification, you can apply to an energy supplier for Smart Export Guarantee (SEG) payments for exported electricity.
