Install of solar panels and battery. The work was carried out as promised and in a neat and tidy way. All the staff I interacted with were friendly and helpful.

Installation of solar panels - experience 4 years on
Customer Service
Quality
Value
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.

PV & Tesla Powerwall install - 6 years later

No problems with my installation - everything continues to run smoothly. 24Mw/ hr generated so far. Average combined elec / gas bill each year is now approx £400 ( including standing charges) - 3 bed detached house - 1 occupant. I do have air to air heatpumps & use the battery to spread the load over the day/night to utilise cheapest electricity rates ( especially in winter!)

Replacement of Solar Edge optimiser under warranty

This is a relatively low-cost item that did not justify scaffolding to replace. After several discussions and a site survey, three technicians were able to access the affected panel and optimiser from the adjacent loft window. They did this safely and quickly. Very good service from Spirit Energy.

Good experience and an excellent system
Customer Service

We started our renewable energy journey with Spirit Energy in early 2021 when we engaged them to plan a solar and battery system for us. We were impressed with the thoroughness of the assessment of our needs and the resulting options offered. We started with a combined solar PV and battery system; the solar was installed in June 2021 and the battery in February 2022 (due to availability issues with the battery system). We were so pleased with the performance of the system that after more calculations and discussions with Spirit, we added a second battery which was installed in February 2023. The system has been running since then with no significant issues and reduces our electricity cost by around 80% every year. As of the date of this review our total savings have been over £7,500 (we are a high usage household). We have been very pleased with Spirit Energy from initial consultation through to installation and subsequent support and we'd certainly recommend them to anyone considering a solar and/or battery system.

Solar Panels, Batteries, EV charger installation
Customer Service

In 2020 I approached Spirit Energy about solar panels and a battery - from the very start the service has been excellent - never too busy to answer, some very stupid, questions. The team explained everything clearly and all elements of the project were communicated clearly. I went ahead with Panels and a single Tesla battery - installed neatly, on time with no fuss and the team made an excellent job of tidying up . Since the original installation, they continue to respond to my questions and I have subsequently had a second battery and EV charge point installed by Spirit Energy. Whilst there have been a few issues they have always worked through these with me and sent engineers back to change the sensor to ensure that the energy all goes to the desired locations. I am really pleased with my installation and the service I have received and would recommend (and have) Spirit Energy to anyone considering Solar power or related works. I am now in the envious position of having my energy provider paying me each year . .

So Impressed First Time I Didn't Hesitate To Make A Repeat Purchase
Customer Service

I chose Spirit Energy for a solar installation at my son’s house in February, marking my third solar project after working with both national and local companies. Their service so impressed me that I immediately hired them again for a rental property. What sets Spirit Energy apart is their passion, attention to detail, and ability to exceed customer expectations. Archie, my main contact, maximised the roof space by using Jumbo Panels, ensuring greater solar coverage and a better return on investment. Rachel expertly managed the project, communicating clearly with tenants, agents, and myself to minimise any disruption. The install was efficient—thanks to doubling the roofing team, the job finished in under five hours. Electricians Klem and Will, who I had met during my son’s installation, handled the battery system with outstanding professionalism. Though I’m not local—Spirit Energy is Reading-based, while the installs were in Worcester—they delivered top-quality work that’s worth every penny. With Spirit Energy, it’s not just about cost; it’s about peace of mind and maximising value through expert installation.

Spirit Energy installed my solar power and Tesla Powerwall system in 2023 leaving a cable tail ready for an EV charger that might be required at some later date. I was impressed then by the exceptional standards of planning and communication together with the quality and professionalism of every aspect of the workmanship on site. Give this earlier experience I had no hesitation in asking Spirit to instal the Hypervolt charger now needed for a newly acquired EV. It is notable that even this relatively simple, straightforward task attracted the same high standards and attention to detail as the original main installation. To my mind Spirit Energy is a standout company, to be highly recommended.

Smooth expansion of existing system
Customer Service

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.

We're really pleased to hear that we were able to support you quickly with the Powerwall 2 warranty replacement and that upgrading to the PW3 has opened up new possibilities for your PV system. It was great working with you again to find the right balance between cost and performance, and we're delighted the installation went smoothly - even in that awful weather!

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.
