Smooth expansion of existing system

After my Powerwall 2 failed due to a known issue, the Spirit team was supportive in arranging a warranty replacement as quickly as possible. The replacement (a PW3, which has an integrated inverter) opened the door to expanding our PV system so naturally it was a good opportunity to investigate possible options. The Spirit team were attentive and helpful in determining the best balance of cost vs return and quickly came up with a suitable design. I expected a reasonable wait for installation and was pleasantly surprised when they found a slot not long after agreeing the project - even then, the installation was performed much more quickly than anticipated, despite the terrible weather. Just like my experience with Spirit four years ago, the team did a great job, leaving a tidy site. They were great to chat with, answering any questions along the way and ensuring we fully understood the updates and changes made to our existing system. Its great to work with them, they uphold the same standards that won my business the first time around - highly recommended.

From the first contact to the completion of our installation, Spirit Energy have been thoroughly professional at every stage. Taking into account our personal preferences and our East/West facing property, they designed a bespoke solution tailored to maximise our system's performance. No plan can account for the type of weather we experienced during late December and early January, but throughout, Spirit Energy kept me updated with the revisions to the schedule and the installation team went above and beyond to get the system fitted. We would like to thank the whole team for their dedication, in particular: Nathan, Natasha, Ryan, Will, Simon and Chayce.

This is a company that really knows its business, applying technical knowledge and its organisational and installation experience to make my project successful. The whole process, from my initial enquiry through quotation and surveys, to obtaining approvals and to the very neat and tidy installation, was handled very efficiently with good communications maintained throughout. The comprehensive final handover and the instructive website impressed as well. It was a pleasure to work with such a thoroughly professional company.

We were very impressed with the installation of our solar panels & batteries by Spirit Energy. From start to finish communication has been excellent. The scaffolding was put up just before the installation started and taken down again as soon as the roof work was completed. All the personnel from both the scaffolding firm and from Spirit Energy themselves were polite and friendly and the work was carried out with care. All packaging was removed at the end of each day and the site was left tidy. All in all one of the best experiences we have had with regard to work being carried out here.

Spirit Energy were friendly, efficient and easy to deal with. The installation, which wasn't the simplest, was very neatly achieved. The only problem, not ultimately Spirit Energy's fault, was that the Tesla PowerWall 3 failed to take any charge and had to be replaced. This was efficiently handled by Spirit Energy and I was up and running 3 weeks later.

We couldn't be more delighted with the solar system Spirit Energy have installed at our house and how the installation has gone. From very first contact with Spirit's sales team, through to the system finally being handed over, the company has been a pleasure to work with. Within days of making first contact with the company, Archie, from Spirit's Technical Sales team came to our house to carry out an initial survey and suggest what kind of system would work best for us. The sales process was highly professional and included a detailed quote, including estimated cost savings we could expect to make and how long the system would take to pay for itself. The initial visit by Archie was followed up by a more detailed technical survey by Justin, Spirit's Head of Installations. Throughout the sales process, we always felt entirely confident that Spirit were experts in their field and were making the best possible recommendations. We ended up agreeing to buy a 40 panel system with two Tesla Powerwall 3s and a myenergi Zappi EV charger. The entire installation was overseen by Peace, Spirit's Project Manager. Without exception, everyone in the team who carried out the installation did a great job in quite difficult weather conditions and were a pleasure to have at our house. Now the system is live, it's very satisfying to see that even though we’re in the depths of autumn, the system is already producing and offsetting enough energy to make us almost fully independent of the grid.

We had solar panels for several years before we added the Tesla PowerWall 2 battery fitted by Spirit Energy. What a difference that has made to our bills. We chose Spirit after interviewing several suppliers, because their thoroughness and depth of expertise really impressed us. The installation involved wiring through an outside wall into a very cramped understairs cupboard, which they managed perfectly. I'm writing this review five years later because we're in the process of selling our house and have been asked for copies of guarantees and electrical installation safety certificates. A quick chat with a friendly and helpful person at Spirit, and they were in my Inbox in minutes. What a reilef. Brilliant service!

I was drawn to Spirit Energy for our downsizing project in Cardiff by their excellent YouTube series on renewable energy. From our initial contact with Tok Charles, the whole project proceeded smoothly at the pace dictated by our builders (it took over 10 months); Spirit never pushed us for sales completion in any way. Our project manager, Natasha and both sets of installers (30 PV panels and later a Tesla Powerwall 3) were highly professional, helpful, and friendly. Spirit Energy is a joy to deal with, fair value for a top-flight service, and I recommend them to anyone seeking to install or upgrade their renewable energy system.

Excellent, very happy with the installation of Aiko panels with associated Enphase microinverters and a Tesla Powerwall 3. From the initial review and discussions with Nathan through to the survey by Justin and the installation by Ben, Jozef, Klem and Dan, managed by Peace, the work undertaken was of the expected high standard. Late customer changes were competently managed by Peace without affecting overall schedule. Some issues identified during commissioning were equally competently managed and resolved in a timely manner by Peace and Ryan. Another mention must go to the scaffolders. Blue Scaffolding, based in Reading, were efficient and courteous during the installation, paying attention to the restrictions defined during the survey. The subsequent removal of the scaffolding was completed on schedule. Such a difference to some other scaffolding companies we have experienced. Overall, we highly recommend Spirit Solar in terms of competitive pricing, attention to detail and work of a high quality.
