Qualiturn’s aim is to be one of the greenest subcontractors available in the UK, producing subcontracted Turned & Milled components. Our factory uses power from 130kw to 160kw per hour. Our new system along with the existing panels, will give us the potential to produce 200kw We will now be helping our customers with the carbon reduction and CBAM requirements of their products. Thank you to Excel Energy for the install, support and advice to achieve these targets.
Nicholas GroomManaging Director ⭐⭐⭐⭐⭐
A site visit from Nick Neza left me in no doubt that my solar installation was going to be in good hands with Excel Energy and I wasn't wrong! The quote was favourable, the whole process was smooth and efficient. All the various permissions were obtained by Nick, the attention he gave to detail was thorough and so very reassuring. The installation team were simply magnificent. Ploughing on through rain and shine, their work ethic was truly amazing. I could never have imagined the project being completed as it was. Nothing was too much trouble, simply first class!
Royston SumnerFort Stamford, Health And Fitness, Owner ⭐⭐⭐⭐⭐
Excel Energy were very knowledgeable and responsive to our requirements. We ordered a 7.2kWh solar PV system with Solar Edge battery and inverter, and the team that came to install did an excellent job. I was impressed with their good attitude, attention to detail and high quality of workmanship. I would recommend anyone considering a PV solar system use Excel Energy. I have been so impressed with their work and the performance of the system installed at my home that I have just commissioned them to do a commercial installation on my business premises.
John MLimlab, Director ⭐⭐⭐⭐⭐
Great team to work with. We had issues getting approval from national grid on our system Excel Energy kept me informed through the process. When we had approval the installation was carried out in no time.
Glenn WilsonFacade Hoists, Director ⭐⭐⭐⭐⭐
We were looking to put Solar Panels on our farm buildings and had researched a few different companies, but found Excel Energy to be the most competitive. The service and support we have received from Nick Neza has been amazing throughout the whole installation process. He visited us on the farm, went through everything with us, planned the job and gave us a timescale. The team of men turned up on the planned date, fitted all the panels, installed all the electrical equipment and commissioned the system within the planned timescale. All the paperwork has been excellently planned. All certificates have been received. If there are any problems or queries then Nick is available at any time. The company has been excellent all the way through the whole process. We thoroughly recommend them.

I have known Nick for a few years, and his installations/commissionings are first-class. Would highly recommend his workmanship.
Joe MartelloRoscomac, Director ⭐⭐⭐⭐⭐
Nick Neza and his team have just installed a Home SolarEdge Battery and Backup System for me. They did a great job, no fuss, all good despite a software version issue between the relevant boxes. They even came back on a Sunday to work on the problem. Overall, a very good service, the problem was not of their making and they sorted it out with no fuss.
Dave B⭐⭐⭐⭐⭐
The installation itself was meticulous, and the team was both friendly and knowledgeable. They navigated the complexities of my building with ease, proving that no job is too complicated for them. If you're looking for a reliable and skilled company for EV charger installation, I wholeheartedly recommend Excel Energy Ltd. They turned what seemed like an impossible task into a seamless experience.
Amir⭐⭐⭐⭐⭐
Having looked at several other installers we decided to go with Excel Energy. From the initial survey right through to installation & commissioning the service and attention to detail was outstanding. We installed a 18.48kwp Solar PV System & a couple of EV Chargers. Nick & his team were extremely professional in every aspect of the works. Special mention to Bled the supervisor for his never ending patience! I absolutely would recommend Excel Energy for your Solar PV System installation.
Patrick AhernCharity For Civil Servants ⭐⭐⭐⭐⭐
Solar in safe hands! Nick and his Team at Excel Energy have done a great job supporting a refit, service and upgrades to our Business systems. Everything was on time, as quoted and additional support provided when asked. Good job!
Joe MRoscomac ⭐⭐⭐⭐⭐
Nick from Excel Energy supervised the installation of our ground mounted panels with battery back up. This was done carefully and to a very high standard. We are now enjoying free electricity and earning money from feeding surplus into the Grid. I would also like to thank Nick for his patience guiding me through the procedures so that I can now see what is being generated by each panel on my computer and mobile phone. This is addictive!!
Nick JonesLamberhurst Farm ⭐⭐⭐⭐⭐
After meeting a number of Solar companies, Nick and his Team at Excel were by far the most helpful when it came to designing a system which needed to be split over multiple roofs and have no visual impact to the unique design of the building the panels sat on or the surrounding area. Very happy customer.
Nick Herridge⭐⭐⭐⭐⭐
We would like to express our appreciation for the excellent service provided by Nick at Excel Energy Ltd. He efficiently installed our replacement SolarEdge inverter and seamlessly integrated it with our existing SolarEdge account. Thank you for your professionalism and expertise.
Michael H⭐⭐⭐⭐⭐
We have just had Solar installed by this excellent Company. Led by Nick, who was knowledgeable, helpful and efficient all the way through the process, everything went smoothly. The team of installers were courteous, conscientious and hard working. Everything was installed, up and running within a week. Impressive!
