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.

* Savings Calculations
The savings calculations follow MCS’ official guidelines and are based on a typical 4.95 kWp solar panel system installed in Southampton on an unshaded south-facing roof with a pitch of 40 degrees, with 10.36 kWh of battery storage. The home’s electricity demand is 5,000 kWh per year, the cost of grid electricity is 24.86p per kWh, the occupants are in during the day, and they are signed up to Octopus Energy’s ‘Outgoing Fixed’ Smart Export Guarantee (SEG) tariff of 15p per kWh (you must be an Octopus Energy customer to get this rate – other SEG rates are available with other energy suppliers).
