Tethys Energy Ltd

In my experience it's rare to find a knowledgeable and passionate tradesperson that delivers what they say, when they say, all whilst providing a great service. I'm pleased to say Jason did this from first contact to final email confirmation. If we move house and it doesn't have solar panels there's only one person we'll call. Thank you for everything and all the best.

Jason Fuller provided a thoroughly professional service from start to finish. He was prompt, clear and courteous. He came to remedy a fault from work undertaken by another supplier, and his thorough investigation into the causes of the problem and what remedial works might be required went way beyond my expectations. As as result of his initial investigation, he was able to diagnose exactly what was needed. He recommended a new inverter and battery system and when this was delayed because of circumstances beyond his control, he was quick to communicate this issue. The installation work he did was done without fuss and was to a high standard. I am very satisfied with his work.

Jason has just completed an installation of a PV Panels, Battery, Inverter and EV charger at our home. This technology is complex and needs a lot of knowledge and skill to get right. Jason has this knowledge and provides honest advice/guidance. After just over 1 week of hard work including – re-cabling, new cabling, new circuit board elements, scaffolding, roof installation, full testing and set up of the software that runs all the components (we have JA Solar Panels, GivEnergy Battery, Solar Edge Inverter, Zappi EV Charger), all handled seamlessly by Jason, we now have a full working system. Jason also has knowledge of and handles the District Network Operator (DNO) documentation, making the whole service relatively seamless from our point of view. If you are going to do PV Solar you need someone with this type of knowledge. The installation experience was also great. I always knew what was going on and when, Jason (plus team) were always on time, neat tidy and considerate. All in all a great experience and I am now looking forward to learning what our system will do over time.

I obtained four quotations for a new Solar Panel (possibly with battery) installation. As I dealt with each supplier, I learned more and adjusted my requirements. Jason won the order because he had been so helpful and patient with my questions and changes because he was able to give me the best arrangement of panels and a battery that was affordable. His final quote was for a 3.6 kW pk system comprising 2 sets of 5 all black LG panels built into my 2 small South and East facing slate roofs. Included was an 8kWh GivEnergy battery and hybrid inverter and a My Energi Eddi to heat my hot water. He met all my requirements at a good price. Jason started on time but final completion was delayed by a hold-up in the battery delivery - not his fault. I found his quote and his work were of a very high professional standard and the wiring and mountings were all impeccably neat. He was a pleasure to work with and, unlike some other quoters was not at all "pushy". At all times before, during and post contract his attention to customer service has been outstanding.

Jason installed 15 panels for me. His work was exemplary, as was his advice, timekeeping and tidiness. I was very satisfied with the whole job. I would highly recommend Jason.

Very knowledgeable, and took the initial planning etc very seriously. Gave an honest assessment of the options. Always responded quickly to queries. All work was carried out on schedule and with minimal disruption. Very neat and tidy. Would definitely recommend!

Jason from Tethys recently completed a 6.4KWp solar PV system. I am delighted with the professional service that Jason provided from pre sales conversations through quotation, navigating the necessary approvals , securing the deposit with insurance and then an excellent installation and handover . I would recommend him to anyone considering this type of system , his technical knowledge is explained to a novice like me and gave me the confidence to proceed with this investment.

Following some squirrels nesting under the panels, it was necessary for the installation to be checked, any damage repaired and have mesh added to prevent further unwelcome visitors. Jason provided an accurate quotation and is quick to respond to email queries. The work was completed professionally, on time with no fuss. Full details of the repairs to some chewed wiring were given in the PV audit report. I would not hesitate to recommend him and his team for any maintenance work (and for installations) as it's clear he is extremely knowledgeable and has great attention to detail.

We chose Tethys after getting several quotes from other PV installation companies. Jason was quick to respond to all queries and provided a detailed quote that fully met our needs. The installation was carried out efficiently as planned and we are very happy with all the standard of the work done. Jason obviously prides himself in customer service and I have no problem recommending him.

We decided to install PV panels when we had our roof tiles replaced. Jason was recommended as a supplier and he was quick to respond to our request for a site visit and his subsequent quote was detailed and comprehensive. Throughout we were kept informed and he helpfully agreed to coordinate the installation to follow the roof work, meaning we could use the scaffolding for both jobs. We were very satisfied with the whole process from the initial enquiry through to after care and connection with Solar Edge monitoring and we would have no hesitation recommending Tethys Energy as a suppler.
