“They provided clear and concise information without overwhelming me.”

David Mellor

“On 1st installation, I was sent an incompetent engineer, BUT then I was sent an excellent engineer. However, the 1st guy had mis-wired the FITs meter, which did not record readings. Another engineer came and rewired it. There was a delay in compensating me for the missing readings, BUT Mr.Jenkins, managing director, sorted it all out. Full repayment plus a voucher. All’s well that ends well.”

Chris Jones

“Having previously ordered solar panels from a different company (now gone bust) and being messed around for seven months, we were given the details for Celtic Green Energy by a work colleague. The support, understanding and workmanship from CGE has been superb from day one. There was a lot of apprehension, on our part, to order from another company but I’m extremely glad we did, particularly now the summer. Comparing our energy use from this year to last, our daily consumption from the grid has dropped from over £15/day to less than £3! Our system was complicated to fit due to the slate tile roof, energy diverter into an already bizarre heating system and the addition of an RCD all added to the woes. Regardless though, everything was completed within 6 weeks of first making contact with CGE, and all work was carried out to a high standard. I’d happily recommend this company to anyone looking to install a solar PV system in their home”

Huw Bosher

Cecilia Morreau, Llangadog

“All the workers from Celtic were very professional, polite and clean workers when installing our Solar Panels. The electrician who worked in the house wore overshoes whenever he came indoors. He was also very helpful when I needed to set up my app. The office staff were also very polite and helpful.All in all very pleased with the entire process from my initial enquiry right up to completion. Would definitely recommend them.”

Juergen Maedge – Gorslas

“Very happy with the service and product provided by Celtic Green Energy, love my new solar panel and battery system. Great communication throughout and quick installation from a friendly and courteous team.”

Richard Whittaker – Newport

“I have an awkward roof to my house in terms of access, even more so after a conservatory was built where scaffolding would ideally be erected. This problem eluded tenders for solar panels until Mr. Stuart Jupp visited whereupon he told me his roofers could gain access without the need for scaffolding. This indeed was the case with his expert men doing the job perfectly and safely.

Such expertise was matched electrically with his well-qualified engineer installing the inverter and storage batteries with much advice and assistance to follow up as needed.

So all in all well pleased and with electrical tariffs spiralling ever-upwards very glad to have the system working so well. “From start to finish the service and product was superb. The surveyor was very knowledgeable and prepared an accurate and realistic proposal based on our needs and expectations. The scaffolding was erected professionally and without incident which was a particular concern to us with our raised decking. The installation team of roofers and electricians were polite, professional and skilled tradesmen. I couldn’t be more happy with my 18 panel and 3 battery system. Absolutely first class!”

Shane Davies – Bury Port

“Very happy with the service and product provided by Celtic Green Energy, love my new solar panel and battery system. Great communication throughout and quick installation from a friendly and courteous team.

Gethin Williams – Llanelli

We were fortunate enough to contact Celtic Green Energy when our solar panels were blown off our roof during Storm Eunice in 2021/22. We were anxious and very careful who we contacted to complete the solar panels, as we had been ripped off before by another solar panel company. When we contacted Celtic Green Energy we were greeted by a very friendly receptionist who seemed to know what she was talking about.   She then passed us on to one of their staff who arranged to come and see the damage.  We were in contact with our Insurance Company and advised them that Celtic Green Energy was going to complete the work with their permission. My Insurance Company ensured that the work was carried out in a specific manner and Celtic Green Energy completed this work.  We have been very satisfied with the way the solar panels are working and would certainly recommend this company.

Kath & Peter Mepham – Ogmore by Sea 

“Celtic Green Energy are a very good company to employ, they say what they can provide, get the job done and hooray it works!

They help with the paperwork required, and it is correct. South Wales is lucky to have a service like this on our doorstep. They come when they say they are coming and clear up after themselves.”

Christopher Slader- Llangennech

“I called Celtic energy for a quote to install a Solar panel system, from the first contact they were very professional and made an appointment to review my requirements and house for suitability for a system.

As you can guess I had many questions to ask the representative who was keen to as answer my questions. This was backed up with a summary of the proposed system’s likely efficiency and detailed quote, what further impressed me was the proposed use of better quality reliable components.

I was confident in placing an order and was given an installation date which was kept to by Celtic energy, as this was so the system would be up and running before my holidays.

The installation was fuss free and very quick taking about a day, there was a high standard of work carried and everything was cleaned up and left clean and tidy upon completion, and with the system workings explained in detail.

Happy with the system and installation process by Celtic energy and would define recommend.”

Stephen Roche – Cwmbran

Thanks Celtic Energy for your help in getting my faulty inverter replaced under warranty, the manufacturer, SMA,  was completely unhelpful until your firm got involved.  My special thanks to Berth who was instrumental   in resolving this problem.”

Ron Woodland – Llangennech

I was introduced to the company through Richard Morris who arrived to complete a survey for a quote on my property. Richard listened to what I wanted and what I was expecting and with his knowledge Richard designed a system that would work for me. Richard was also very informative, and very helpful when it came to answering any questions that I had.

 Throughout the installation process we did come across a few problems with materials & poor workmanship – which were eventually rectified through speaking to the very supportive Stuart Jupp.  I’m now 2 months into my solar journey – looking forwards to more sunny days!

Oliver Joiner – Fforestfach

“I installed my solar panels back in the Spring of this year. The team of installers was very professional and completed the work without any fuss.


The panels themselves have provided a huge amount of electricity to the house due to the long sunny days of this Summer and the battery has been at 100% over a long length of time. To date compared to last year my usage through the grid is down by 22%.” 

Ian Lewis – Llanelli

“We purchased solar panels with yourselves in the middle of October and they were fitted at the end of October which was extremely quick. They were supplied and fitted very efficiently and we are extremely pleased with the fitting and after sales service. The installers who came to fit the panels were very polite and it was a pleasure to have them in our home. We did have a slight problem with the electrics tripping out but this was dealt with very quickly and in a very professional manner. I would strongly recommend Celtic Green Energy to anybody.”
