Solar Energy Systems Installation Costs

The cost of your solar energy installation and entire system will vary greatly depending on many factors, but using the right solar energy company will make all the difference. We keep a close eye on our competition to ensure that our prices are competitive and fair so you can rest assured that when dealing with Tethys Energy you get the right deal first time round.

Not all solar power installation companies are created equal.

Many solar panel companies will charge astronomical mark-ups on their services, or will low-ball their estimate, and then add in hidden costs and fees throughout the project process. Here at Tethys Energy we make sure you know what to expect and how much it will cost you from start to finish.


Your Guarantee

With Tethys Energy, there are no hidden fee's, what gets quoted, is what it will cost you. All of our work comes with a 100% no quibble guarantee of workmanship, backed by NAPIT, RECC & MCS for your complete peace of mind.

Excellent work...

"On time, on budget, professionally done and set up, including replacement of an inverter which was broken on arrival. Top of the line equipment used throughout."
BJ Thompson

Prompt and efficient...

"Jason did a great job of getting my PV array back working. I have recently taken over the array from another family member, so did not understand anything about it except that it wasn't working. Jason came, quickly figured out what the fault was, and fixed it with no fuss or bother."

Crispin Keable

Fantastic Service...

"Jason responded to my request for a second opinion promptly. I was "cold called" by a company offering a free check on my 6 year old solar energy system. They then tried to tell me the system was working at 72% capacity, that they would replace my inverter and install optimisers for £5,500 but special offer if i signed a contract there and then for £4,500. Needless to say I declined. I contacted Which? Trusted Traders for advice and was given Jason's name. He checked my system, found no problems and told me if anything it was performing better than expected."
