High quality installation from Spirit Energy

My system was installed in January 2023 and has been running perfectly for 2½ years. It comprise three solar panels and 13.5kWHr Tesla Powerwall2. Given that I get electric car charging rates from Octopus Energy, I use overnight electricity to top up the battery (plus solar) and never pay peak time rates. Apart from car charging, I use about 7kWHrs a day to run the house which is perfect for my system design. Lat year my solar panels generated just over 1MWHr of energy which represented about a quarter of my total electricity usage (including car charging). I chose Spirit Energy through a recommendation from Tesla UK and had no previous knowledge of them. I feel I made the right choice as their performance in understanding my requirements and the design of a system that matched this was really excellent. The quality of installation and commissioning work was professional and I have experienced no problems since it was installed. We have lived through a number of electricity feeder issue in our road and each time the Powerwall has isolated itself and then resynchronised so we did not notice the failure. They are a great company to work with and I am very happy to recommend them for their professional engineering and installation skills.

I have been really impressed with Spirit Energy team. I had 18 panels and Powerwall 3 installed two weeks ago. From design to commissioning the process has been smooth, overcoming complex challenges which has resulted in a neat install with minimal issues. - No issues with scaffold - No issues with mounting and installing panels. I was worried about cables under the panels and bird mesh on some of the corners not flush to tiles but have been assured these are not issues - Powerwall 3 install and wiring in the garage is neat and hardwired to my router - Wiring from garage to the utility, on the other side of the house is neat. - Wiring of the gateway in the utility is neat. - Commissioning and handover was thorough with all the documents post install received prior to paying remaining 10% of my invoice So far, no issues with wind, rain and the system is running well. Can't wait to export! BIG THANKS to Tok, Matt, Sam, Ari, Harry, Peace and Justin for being patient with all my questions. Matt especially took care to understand my concerns and step me through every inch of the install. Thank you

I cannot speak too highly about Spirit, who were professional, courteous and responsive throughout the whole process from initial inquiry, design, installation and post-install follow-up. I've been using the system without fault for over a year now, and it has generated in line with Spirit's very realistic predictions that were incorporated within the quote and the estimated payback periods. All their staff seemed to be very expert at what they do, and there were no faults at all throughout the whole process, all of which was taken care of by Spirit, such as arranging scaffolding, etc.

Tesla Powerwall 2

Spirit Energy arrive to fit a Powerwall 2 with non back up gateway in Aug 2019. My first impression on meeting the engineers was how professional they were. They explain the install, ask where I would prefer it fitted, advising on the best location. The chaps took most of the day doing a very neat installation and then downloaded the Tesla App and explained its use. I've been so impressed by the Powerwall and the savings I’ve made that in Aug 2023 Spirit energy installed a second Powerwall 2, this time I had the full backup gateway fitted with it. I now have a heatpump and my word, having the two Powerwall has made a huge difference to my energy bills. Would I recommend Spirit Energy? Absolutely. They may not be the cheapest but as I’ve learnt in the past, buy cheap buy twice. As for the Powerwalls I can’t fault them, they just run in the background charging on cheap rate power and discharging during the day. What’s really clever, if you have solar, the Powerwall will charge fully at night when there’s little solar during the day. In the summer, when lots of solar is available, they partially charge at night to leave space for solar.

Thank you so much for taking the time to leave such a detailed review, and for your loyalty over the years. It's brilliant to hear that our team made a strong first impression back in 2019, and that the quality of the installation held up well enough for you to come back to us in 2023. Two Powerwall 2s, a heat pump, and a backup gateway is a serious setup, and it sounds like it's doing exactly what it should. Your point about the intelligent charging behaviour in summer versus winter is spot on, and it's great to see a customer getting the full benefit of that. "Buy cheap, buy twice" sums it up better than we ever could. We'll be sharing that one with the team.
A Professional Job and Great Customer Service

Spirit Energy did an excellent job of our solar panels & battery installation, from initial contact, through quote, site visits, and the onsite implementation. At every stage they provided a professional service with good communication and assistance with any queries or problems that arose throughout the process. They are not the cheapest, and stated this from the first contact. However I consider that it was well worth paying more for the peace of mind and high quality of the work. They also provide an insurance policy (HIP – Home Insurance Policy) against loss of deposit and the risk of their no longer trading, so that their warranties are guaranteed (up to 10 years). This is why they cost more. The GivEnergy system has worked reliably, and in conjunction my Hypervolt Home 3 EV charger and Octopus Intelligent Go tariff, has resulted in a huge reduction in my energy bills and motoring costs. I have found ways of using the system to move 93% of my electrical consumption into the very low cost 6 hour overnight rate from 11:30 to 05:30. During the summer months, with good solar output, I affectively have free electricity and motoring. My latest monthly bill (April 2026) estimates my annual costs as £496.77 for electricity and £319.09 for gas (I still have a gas cooker & gas central heating, although this is used far less now that I have installed an overnight storage heater, an infrared heater in an outhouse and an air to air heat pump system for air conditioning and heating).

Thank you for such a thorough and considered review. It's great to hear the whole process, from first contact through to installation, hit the mark, and that you felt the value was there even knowing we are not the cheapest option. Those energy figures speak for themselves. Moving 93% of your consumption to off-peak and seeing bills like that in April is exactly the kind of outcome a well-integrated system should deliver. Thanks again for taking the time, and please do get in touch if there is anything we can help with down the line.

Spirit Energy installed 16 solar panels, associated equipment and Tesla battery at our home. The service was excellent and the team did a great job. The perfomance of the panels has been very much in line with projections and we now import very little power from the grid. We would certainly recommend Spirit Energy to anyone contemplating the installation of solar panels.

I contacted Spirit Energy with fairly fixed ideas on what I wanted. I got a quote for exactly that with very good data on expected performance and how the roof would look with the panels fitted. The salesmen then suggested a much better optimised system and explained the advantages of this and it's better return on investment. I decided to accept his better proposal. During the survey, I was guided through the installation and we mutually agreed on the position of the components and the cable runs. The engineer doing the survey was very experienced and helpful throughout. A few days after the survey, I was contacted by a lady who introduced herself as my project manager and she kept me well informed about progress and timings. Finally, the installation crew were very efficient in their work and during the commissioning set up my control of the system using the supplier app on my phone. All of the people involved are directly employed by this family-owned company and the only subcontractors used are the scaffolders. Everyone was efficient and helpful throughout the whole process. Now, over two years later, my system generates about 10% better than forecast and exceeds our consumption twice over. Overall, I think I could not have chosen a better company to work with and highly recommend them.

Thank you for such a detailed and kind review. It's especially good to hear that the suggestion to revisit your original spec paid off, both in terms of how the system performs and the return you are seeing. Generating 10% above forecast two years in is a great result, and we will make sure the whole team sees this, from sales and survey through to the installation crew and your project manager. We really appreciate the recommendation. Do not hesitate to get in touch if you ever need us.

Spirit energy installed my Solar Panels in a professional manner. Operators were helpful and I was kept informed at all times. When a problem was identified with the wiring the company took responsibility without any fuss and the problem was put right quickly.

Installation of solar panels - experience 4 years on
Customer Service

Spirit Energy installed our solar panels 4 years ago. Before installation I had lots of discussion with them about the technical details and they were very knowledgeable and helpful. Before and during installation they kept me informed about what would happen and when and they stuck to the schedule. The work was carried out with minimal disruption to us and the installers were friendly and respectful. The solar panels have and still are performing very well and are reducing my electricity bills considerably. As we have a heat pump, this is a major consideration. The heat pump works well with solar, particularly as the heat pump is managed with a Homely smart hub and can come on when there is good solar generation. So bill reductions come through optimising the use of solar electricity generated as well as payments for excess solar exported.

Thank you for sharing this. Four years on and performing well is exactly what we aim for, and it's great to hear the Homely integration is helping you get the most from the solar alongside your heat pump. We're glad the process was smooth from start to finish, and we appreciate you taking the time to leave a review. Get in touch any time if you need us.
