What customers say

Based on genuine customer reviews

Commercial and domestic clients alike report positive experiences with Excel Energy across solar photovoltaic installations of varying scale. More than one customer describes thorough site surveys and clear system design, with Nick Neza singled out as exceptionally knowledgeable and professional, taking time to explain the proposed setup in detail before any work begins. Communication is a point that comes up often: clients report being kept informed throughout approval processes, including dealings with the national grid, and note that calls and emails receive prompt replies.

Punctuality and reliability feature strongly, with installation teams arriving on schedule and completing projects efficiently, whether a 12kWp domestic system with battery storage or a 280kWp array spread across factory roofs. Reviewers also value the tidiness of the finished site and the responsiveness of after-sales support. The business is portrayed as a one-stop service spanning design, commissioning, installation and ongoing maintenance, with customers mentioning safe working practices and respect for site protocols. A building firm collaborating on multiple projects highlights organised delivery and clear communication. Recurring satisfaction centres on technical expertise, dependable scheduling and attentive follow-up long after handover.

Excel Energy recently fitted solar panels to our barn to power our farm. The process ran very smoothly with a quick and efficient job. We are very happy with our solar and making lots of lovely electricity.

We’ve worked alongside Icarus Solar Energy on a number of projects now and have been consistently impressed with their professionalism and quality of work. As a building company, it’s important for us to work with contractors who are reliable, organised, and deliver to a high standard — and the team at Icarus do exactly that. Their communication is clear from start to finish, they integrate seamlessly with other trades on site, and their solar and battery installations are always completed neatly and efficiently. It’s refreshing to work with a company that genuinely takes pride in what they do. We wouldn’t hesitate to recommend Icarus Solar Energy to clients and look forward to continuing to work together on future projects. — JL4 Group

Exceptional Service from Start to Finish! ​I recently completed a solar PV project with Excel Energy, and I can't recommend them highly enough. From the initial contact to the final delivery and installation, the company was proactive and excelled in every single aspect. ​The communication was outstanding—they kept me informed at every stage and were always available to answer my questions. The installation team was professional, efficient, and clearly took pride in their work, ensuring a seamless setup. ​Knowing I was in such capable hands made the entire process stress-free. Thank you, Excel Energy, for a fantastic experience and a job truly well done. I look forward to the future with my new system!

Nick and his staff arrived on time on the agreed day and completed a excellent installation in a week, and left the site clean and tidy. The after sales service is excellent- they are to be recommended.

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!!

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 truely amazing. I could never have imagined the project being completed as it was. Nothing was too much trouble, simply first class!
