“Jason at Tethys Energy provided me with a quote and was very patient in discussing the figures with me as I was not an expert on the subject. He left us to make our decision in our own time. The work was carried out in a very professional manner. The panels are working and we are very happy. Tethys Energy provided an insurance policy to protect my deposit and warranties. I have no doubts in recommending them.”

“Professional, reliable, punctual and personal, Jason Fuller at Tethys Energy really knows his stuff. You can go through sales reps reading from scripts at call centres or else you can call Jason and talk directly to the guy who understands the technology and the admin and who actually does the work, and at a very competitive price too.”

“The entire process was a very good experience. The quotes were very detailed with clear optional areas. The installation was over 2 days and went very smoothly, with the system up and running with no problems. Highly recommended.”

“Impressively good solar panel installation. Tethys Energy gave a clear and concise quotation. Excellent communication, high quality of workmanship and very pleasant to deal with. Good follow up post installation service. I have no hesitation in recommending for Tethys Energy for solar panel installations.”

” Jason renewed the whole system after we found 5 of our 20 solar PV panels were ‘down’ ” – with a new junction box and individual optimiser on each panel, plus cleaned and pigeon-proofed our PV and solar thermal systems and roof. Everything is working perfectly now. And all the work carried out with a smile – even travelling 2 hours to Kettering was no problem. Recommended.”

“Tethys Energy did the job, efficiently and on time and provided one of the most realistic and reasonable quotes available. Can’t recommend highly enough!”

 “I recently had to contact Tethys Energy who are a seasoned, professional installer of solar PV systems in the UK due to a loss of solar power generation on my 4 kWp system. It transpired that the fault was with the inverter which has now been logged with the manufacturer to swap out.

I found Tethys Energy to be very pleasant and proactive in ascertaining the extent of the fault and did take the initiative to make life as painless as possible for me.

I would recommend Tethys Energy to anyone and I personally know a former colleague who has had a 4 kWp solar PV system installed by them, and who as equally pleased with their professionalism.”

“After being let down at short notice by another company, Tethys Energy stepped in to remove our solar panels for building work and returned at a time to suit us to reinstall them in a more efficient way than they had been previously. I would have no hesitation in recommending Tethys Energy.”

“We have used Tethys Energy as a subcontractor to our Energy Solutions Department over the last 12 months and continue to work closely with their project management team on a number of commercial scale PV installations.

Tethys Energy provide a first-rate service and excellent capability in all aspects of PV installation project delivery including client liaison, sub-contractor and labour management, site supervision, roofing installation, electrical work and system commissioning. 

Positive feedback from our clients, a good working relationship with our employees and a proven track record in successful project delivery means that Darke & Taylor Energy Solutions will happily continue to use the services of Tethys Energy into the future.”

“Tethys Energy were employed at short notice to project manage the electrical installation of a 50kWp ground mount system for a farm shop. It was a complex project with the array over 300m from the incoming supply.

In addition, the DNO stipulated that the export had to be limited to 30kWp which involved installing a considerable amount of new export limiting technology.

Throughout the project, Tethys Energy demonstrated a high level of competence and a willingness to put in long days to ensure the project was completed on time.

I will definitely be using Tethys Energy on future projects and have no hesitation in recommending them to prospective customers.”
