What are the Benefits of Battery Storage?
A home battery allows you to store electricity for later use. Here are the two main scenarios where battery storage comes in handy:
- If you have solar panels, you don’t normally use all of the solar electricity at the moment it’s generated. With a battery, you can capture a good chunk of that excess solar electricity. Without a battery, all of the excess escapes to the national grid.
- A battery can also be charged with cheap, off-peak electricity from the grid, assuming you have signed up to an appropriate tariff with your energy supplier. This allows you to discharge that cheap, stored electricity to your home during the day, rather than pay high peak prices.
HOW DOES BATTERY STORAGE COMBINED WITH SOLAR PANELS ACTUALLY WORK?
- Battery Charging
When your panels are producing more electricity than the property needs at any given time, a sensor will alert your battery’s management system, which will divert the excess solar electricity and store it in the battery.
- Battery Discharging
If the sensor notices that the property requires electricity from the grid to meet its energy needs, then the battery management system will automatically discharge stored electricity from the battery. This avoids paying for grid electricity unnecessarily.
During the day, energy generated by solar panels can be stored in your solar battery in addition to powering your home.
You can benefit from stored electricity from the solar battery, any time day or night, instead of using the National Grid and paying for it.
Battery Storage Key Features
What To Look For
We install all battery storage brands and models currently available in the UK. However, some are better than others. What do we look for in an ideal battery?
- Good manufacturer support in the UK
- Solid warranty
- Low cost per kWh (unit) of storage
- Batteries that ‘just work’ as they should, day after day
Makes and Models we Install
In our opinion and experience, the best and most reliable battery product at the moment is the Tesla Powerwall. It’s tried and tested, manufacturer support is fast and responsive, and it’s very rare for anything to go wrong.
The Powerwall comes in only one size, 13.5 kWh, so if you want a different size battery there are other makes available. Here is a table showing the batteries we install most:
MAKE & MODEL | STORAGE CAPACITY | POWER OUTPUT | WIRING | EMERGENCY POWER? | WARRANTY | |
GivEnergy | 5.2 kWh | 3 kW | AC- or DC-coupled | Additional cost | 12 years | |
SolarEdge Home | 10 kWh | 5 kW | DC-coupled | Additional cost | 10 years | |
SolaX Triple Power | 9 kWh | depends on inverter | DC-coupled | Additional cost | 10 years | |
Tesla Powerwall | 13.5 kWh | 5 kW | AC-coupled | Included | 10 years | |
GivEnergy All-in-One | 13.5 kWh | 6 kW | AC-coupled | Included | 12 years | |

Battery storage installation
They fitted a battery and inverter exactly to my requests and were always ready to answer any questions as the installation went along. They were able to accommodate late changes to the installation (even during the actual day of fitting). I wish all companies were like this.

Quality design, advice and fitting
Came recommended to us and was very happy with the service. When quoting and designing the staff were knowledgeable and able to advise on the most suitable batteries and solar panels and the fitters were professional and cleaned up when they were done.

Very helpful
We chose Infinity Energy Services to install solar panels & a battery after looking at 3 suppliers. They were very helpful at quotation, patiently providing us with alternatives as the project evolved. We were very appreciative that at no stage was there any pressure to commit until we were ready.

Powerwall installation
Infinity installed a solar pv array and power wall battery for us. Their service was exemplary from start to finish. The quote was timely and competitive and they gave us sound advice on the best options for our installation. The installation was completed in a professional manner and the roofers and electricians were a pleasure to have on site.

Tesla Powerwall installation
Infinity added a Tesla Powerwall and gateway to my existing solar setup back in March 2020. Throughout the process the communication was great, the delivery and installation all went to plan and was performed to a great standard and once in and operational they dealt with the DNO paperwork and process to up my battery output to the full 5KW.
