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.

Maintenance of Solar Panels and Mesh Installation
Customer Service
Quality

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.

PV panels installation by Tethys Energy
Customer Service
Quality

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.

Myenergi Zappi Electric Vehicle Charger installation

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.

Removal and Re-installation of PV Panels
Customer Service
Quality

The felt on the underside of my roof tiles had perished and I had to have the roof stripped off for new felt to be fitted. This required my photo voltaic panels having to be removed and re-installed after the work was done. Jason priced for the work, removed the PV panels promptly once the scaffolding had been erected, and re-installed them when the roofing contractor had finished before the scaffolding was removed. Jason was extremely polite, tidy and the PV panels are back in place in full working order. I have no hesitation in recommending him for this kind of work, as he is highly professional possessing all the necessary technical and personal skills.

Jason installed a Zappi home charger which we had chosen with the potential of linking up solar panels at some point soon in mind. The installation went without any problems, Jason was very helpful and knowledgeable, the charger is excellent and works perfectly. I would recommend Tethys Energy and will certainly be asking Jason to add PV's when the time comes.
