Should I get a solar battery for my new or existing installation?

If you’re considering solar panel installation, you’ve probably come across solar battery storage and wondered whether it’s worth adding to your system.

If you’re considering solar panel installation in Somerset, you’ve probably come across solar battery storage and wondered whether it’s worth adding to your system.

Solar batteries allow homeowners in Wells, Glastonbury, Shepton Mallet, Street, Frome and nearby villages to store unused solar electricity and use it later, reducing reliance on the national grid and making better use of renewable energy.

At Tincknell Solar, we install solar panels and battery storage systems across Somerset and help homeowners understand whether a battery is the right choice for their property and energy usage.


A solar battery stores excess electricity generated by your solar panels during the day.

Instead of exporting unused energy back to the grid, the battery saves it so your home can use that power later, in the evening, overnight or during cloudy weather.

This means:

For many homes across Somerset, solar battery storage is a smart way to maximise the value of a solar panel installation.


Solar batteries are not always about quick financial returns. While they can reduce electricity bills, the upfront cost means they are best suited to homeowners who value long-term savings, energy security and sustainability.

A solar battery may be worth it if you:

For environmentally conscious homeowners in Wells and across Somerset, batteries are often chosen for peace of mind and future-proofing rather than instant payback.


The cost of solar battery storage in the UK varies depending on size, brand and system design.

On average, a domestic solar battery costs around £5,000, though larger or premium systems can cost more. High-capacity batteries such as the Tesla Powerwall 3 can range from £8,000 to over £20,000, depending on how many units are required.

Our experienced solar panel installers in Somerset will always recommend a system that matches your home, usage and budget, not an oversized solution you don’t need.

The best battery for your home depends on what you prioritise: cost, capacity, warranty length or smart monitoring features.

As trusted solar panel installers in Wells, we help you compare options and choose a system that fits your goals.


A solar battery can help lower electricity bills by allowing you to use stored solar energy during peak-rate periods.

However, batteries usually take many years to pay for themselves. Savings depend on:

Rather than a short-term investment, solar batteries are best viewed as a long-term upgrade that increases control over your energy and protects against rising energy costs.


Most solar batteries last between 5 and 15 years.

Lifespan depends on:

Keeping the battery in a dry, temperature-stable location and using it correctly helps extend its life.


Homeowners choosing solar battery storage often benefit from:

Battery systems can also be installed without solar panels, allowing homes to charge using off-peak electricity and use stored power during peak times.
