Need Smarter Solar Energy Storage?
Battery storage gives you greater control over the energy generated by your solar panels. Instead of sending unused electricity back to the grid, a battery system allows you to store that power and use it later when your home needs it most.

Great service from Chris and his team.
They installed solar panels and battery on a day with heavy rain and did not stop until it got dark with the final connections done first thing the following morning. Chris explained how everything worked and said any problems or questions just contact him anytime.
We had an issue with the system connecting to the app the following week and after a quick phone call Chris came out that same evening to sort out for us.
Highly recommended and a good price.Clean & tidy install. Very happy, thank you.
Amazing job from the team, very tidy and nice guys. Would recommend to all.
Battery Storage for New and Existing Solar Panels
Battery storage can be installed as part of a new solar panel system or added to an existing solar PV setup where suitable. This makes it a practical option for customers who already have solar panels but feel they are not making full use of the energy being generated during the day.
Without battery storage, excess solar energy may be exported when it is not being used immediately. With a battery system, more of that power can be stored and used later, such as in the evening or at times when your panels are generating less electricity.
Prometheus Electrical & Solar can review your current setup and explain whether battery storage is suitable. If you are also considering solar panel servicing, solar panel maintenance or system upgrades, our team can provide clear advice on the best next steps for your property.

Is Battery Storage Right for Your Property?
Battery storage can be a good option if you generate more solar energy than you use during the day, want to reduce reliance on the grid or are looking for a more efficient renewable energy setup. It can be especially useful for households where energy use is higher in the evening, when solar panels are no longer generating at their peak.
The right battery system will depend on your property, solar PV system, energy habits and future plans. Prometheus Electrical & Solar can explain what battery storage can and cannot do, helping you make an informed decision without unnecessary jargon.
Our team provides professional battery storage installation in Swansea for domestic and commercial customers, with a focus on safe workmanship, clear communication and practical energy solutions.
Frequently Asked Questions
Helpful answers to common questions about solar panel servicing.
A battery storage system stores excess electricity generated by your solar panels so it can be used later. This helps you make better use of the renewable energy your system produces, rather than relying only on electricity when it is generated in real time. For many customers, this means using stored solar energy during the evening, overnight or at times when panels are generating less power. Prometheus Electrical & Solar can explain how battery storage may work with your property and current energy usage.
Prometheus Electrical & Solar installs trusted battery storage systems from leading brands including GivEnergy, Fox ESS, Sigenergy and Tesla Powerwall 3. Each system offers different benefits, such as modular battery design, hybrid inverter options, app-based monitoring, high-capacity storage and backup power features. Our team can explain the differences between each system and recommend a suitable option based on your property, existing solar panels, budget and energy goals.
Battery storage is most commonly installed alongside solar panels, but some battery systems can also be used in different energy setups depending on the property and requirements. For most customers, the main benefit comes from storing excess solar energy for later use. Prometheus Electrical & Solar can advise whether battery storage is suitable for your home or business and explain how it could work as part of your wider renewable energy setup.
The right battery size depends on your solar panel system, electricity usage, daily habits and what you want the battery to achieve. A system that is too small may not store enough energy, while one that is too large may not be the most practical choice. Prometheus Electrical & Solar can assess your property and provide clear advice on suitable battery storage options based on your needs, helping you choose a system that makes sense.
Battery storage can be worthwhile for customers who want to use more of the energy their solar panels generate and reduce reliance on grid electricity. Its value depends on your energy usage, solar generation, tariff, property type and long-term goals. Prometheus Electrical & Solar can provide honest advice on whether battery storage is likely to suit your circumstances. We focus on practical recommendations rather than pushing systems that may not be right for every customer.
