Tethys Energy

We were extremely impressed by the standard of service Tethys offered. Jason and the team were brilliant, and were very efficient when installing the solar panels. Jason always answered any questions straight away.

We chose Tethys Energy after reviewing three good installers partly because of good reviews but, on meeting Jason Fuller, we felt confident that he would be someone we could trust and work with. Tethys did exactly as they promised and, in spite of appalling weather, the job was completed on time and as specified. We recommend Tethys highly.

Jason installed the Zappi, ran new cabling underground from the garage, installed a new electric point in the garage, connected to the Hub, installed a new circuit breaker at the electric meter. Then made sure I understood how it all worked. Jason did a superb job with my installation. He was the only engineer, of the many I contacted, who actually visited my home to conduct a proper survey before giving me a quote. I highly recommend Tethys Energy.

Tethys Energy installed a 5kw solar array with a GivEnergy inverter, a 9.5kw of battery storage, an Eddi solar diverter for the hot water and a backup power supply consumer unit at my home in July 2023. Tethys Energy were always on hand to answer questions, allay fears and give advice before we signed on the dotted line. Jason - the boss- was very quick to respond to phone and email messages. When the installation team arrived, they were delightful - respectful, hardworking, efficient and 100% on board with what they were doing. At the end of the working day they always left things neat and tidy. I think it took them a bit longer than expected for the installation, but they came back the following week to finish things off, commission the system and talk through how everything worked. They efficiently dealt with a minor teething issue we had with Eddi.The office staff were equally helpful with original paperwork, planning and the DNO application. I would not hesitate in recommending them to anyone who is considering solar and battery storage.

Jason was most helpful and thorough from the start of the quote right through to installation and registration of the system. All the work was completed to a high standard and Jason also helped with the necessary paperwork etc. Would strongly recommend Tethys solar , and they deserve the Which rating .

Highly recommended! Excellent service all round, the installation was completed to a very high standard and Jason was very professional and helpful from start to finish.

I can’t recommend Tethys Energy highly enough. I’m rubbish at writing positive reviews, more of a moaner on TrustPilot. I’ll make an exception here though as Jason and his team are fantastic. Their customer service ability is outstanding. The project is tailored for your needs, their response to questions is lightning fast and they’re diligence in getting the right product at the right price and fitted in the right way is superb.Jason is more than happy to help any novice (like me) understand the various panels, inverters, batteries etc that you can choose from and is great at patiently explaining how it all works. He also doesn’t try and upsell you something if it’s not perfect for what you need. We ended up on a slightly cheaper option as it was better for us.Finally the after sale service is better than I have experienced in any trade or tech product I’ve ever used. All of the documentation, the app setup, the guarantees and certificates are sorted by him immediately after commissioning. Oh and it all came in precisely on budget.Use these guys if you want solar panels, period.

Jason installed an EV charger in my mother's house, the whole process was quick and easy. Jason did a great job, I would highly recommend him! Happy Customer!

Jason knows his stuff and impressed us from the start. Ours wasn't an easy installation on an old building with lots of cabling but his advice was spot on and quote was very professional and detailed. He didn't bat an eyelid while we tweaked it, is responsive, patient and polite from start to finish. Can't go wrong with Tethys.

We contacted Tethys to install a Solar PV system and later EV charging point. We are very happy with the installation from initial site visit to finish and felt that Jason and his team were thorough, communicative and brilliant throughout. Highly recommended
