How Battery Storage works?

Battery storage allows you to store electricity generated by solar PV systems or taken from the grid during off-peak hours.
That stored power can then be used when energy prices are higher, during power outages, or at night to maximise efficiency and reducing reliance on your supplier. Some systems also support “islanding” and off-grid functionality, meaning they can continue to power your property even if the grid goes down, keeping critical systems running and offering true energy security.
Suitable for Every Sector:
- Domestic Homes - Lower your electricity bills, use more of your own solar energy, and gain independence from energy price fluctuations.
- Commercial Buildings - Reduce peak demand charges, support ESG targets, and improve site resilience with intelligent battery integration.
- Agricultural Operations - Pair battery systems with solar or CHP for off-grid capability, backup power, or optimised energy use across demanding rural sites.

Biomass District Heating Scheme
We used ESP from recommendation following a couple of failed attempts to get others to quote, one call to Ross at ESP and the ball was rolling. Ross attended site on multiple occasions to asses the site, and offer comprehensive guidance on the best system to use on our site. His staff are all more friendly and helpful, there was a wait on commissioning of the system, and whilst a little frustrating as we were excited to get up and running the time was useful as it allowed us to sort out what we were going to do with our electric meter, is the one we had is unable to measure units to export. ESP also offer A lot of help and advise on sorting this to, we look forward to the saving on return of investment, and would not think twice to use ESP again for any similar projects.
Nicholas Hilyard
The team were fantastic, From quoting through to order, install & commissioning, they were super responsive, incredibly competent, and nothing was too much trouble.
They put up 22 solar panels, a Tesla Powerwall 3 battery, connected two energy supplies into 1, dug trenches between buildings, installed a Cat6 ethernet cabling system AND kept cost reasonable with no shocks. Above all, they were nice guys! I cannot recommend this company strongly enough.
Dez O’Connor
Superb local company who service our Austrian biomass boiler with expertise and resourcefulness. I've been happy to recommend to my friends who also have biomass boilers. I'm very grateful to the ESP team and their knowledge and responsiveness.
Jonathan Davis
Wonderful local company to work with! ESP Energy have worked with us at BeaverFit UK for the last year on our solar panels and they've been an excellent help, very consistent with great communication!
Would 100% recommend for future use.
Shannon Clarke
Very knowledgeable firm. Ross and team are able to cater and put packages together to suit individual customers within the renewable sector.
Used myself for solar install, project completed on time and to a high standard.
Harry Dodd-Moore
Great business to deal with! Ross was great from the outset with recommendations on how we can drive our business to net zero! A big step forward!
Thank you all!

We purchased a solar energy system, including a battery from ESP. It has been over 12 months since the system was installed, and it has worked/still is working brilliantly. Our energy bills have decreased massively, especially being able to store energy in the battery.
Ross and his team were friendly and professional and answered any questions we had about the products and service.
Having received such a great service from ESP, I approached them about providing sponsorship for our local primary schools summer fayre. Without hesitation they offered their support and helped the school raise vital funds. Would highly recommend this company for their service and high quality solar products.
Madeleine Good
ESP installed the Solar panels and battery at our Village Hall. We are extremely happy with quality of workmanship and the savings on the Hall's energy bill.
Many thanks ESP.
Russell Purslow
ESP energy did a full installation of a pressurised water system and storage system along with a smart underfloor heating control system. They did this in one of the most remote part of the Snowdonia national Park on a totally off grid building and we honestly couldn't be happier with the work they did.
To say the weather was against them was an understatement and they still carried on and did the highest standards of work.
I would highly recommend the ESP team to anyone. They were extremely professional, high quality work and knowledge and most of all a great company to work with. Many thanks for everything you did for us!
Joshua Feilden
Best decision I've made this year to choose ESP to supply us with solar panels, I cannot fault their service from start to finish we were treated like individuals and our requirements important to them, starting with a face-to-face meeting to discuss our options, the manner in which our choices were explained to us verbally and on paper were easy to understand, nothing appeared too much trouble.

FAQs
Yes. Most modern solar systems are compatible with battery upgrades, and we can retrofit storage to most existing installations.
That depends on your energy usage, solar generation, and goals (backup, savings, off-grid, etc.). We’ll help you choose the right system during your consultation.
Yes, especially when paired with solar PV and/or CHP. We specialise in off-grid and hybrid systems for rural and agricultural sites.
With islanding-enabled systems, your battery will automatically disconnect from the grid and continue to power key circuits in your property.
Most systems are rated for 10–15 years or 6,000+ cycles, depending on the brand and usage. Warranties typically range from 5 to 12 years.
