Our Work

Tanjent Energy

The whole process was really smooth and professional. Everything was straightforward, and the information provided was clear throughout. The team understood my requirements and installed everything properly, and we haven’t had any issues since.

exactly what I needed.

This is our second install from Tanjent and a testament to how good we thought their service was and the equipment they specified. This time we had Solar as well and I am happy with the whole process from survey to installation and the final finish. The quality was great as usual and well thought out. I would highly recommend this team for their courtesy, knowledge, expediency and quality of finish.

Quick quality service

We are very happy with our solar installation by Tanjent, which was a few years ago but still working really well. The thing we appreciated the most was that everybody we interacted with were friendly, professional humans who care about their work. I wouldn't hesitate to recommend Tanjent to friends and family (and indeed I have already done so).

Great company - would recommend

We had two quotes from Tanjent about 18 mths apart and in between the team were very patient with us as we changed our building specs several times.
Very happy in the end, now producing lots of exported power.
This is a fast moving industry with fast moving technology so make sure you make a detailed list of your personal requirements & do lots of research. 
The apps and website data analysis is very amateurish, but when all is said & done its the payback you're after not deep data collection. 

Solar panel, battery & inverter installation 

Very grateful to Jason when I enquired about our solar system)which was installed by a different company),  was not working correctly     - the inverter was flashing red. He took the time to ask what was wrong and suggested a few things for me to try to get it back on which solved the problem and saved me a costly call out. 
I was impressed with his professionalism and readiness to help.
I would not hesitate to call this company if I required help in the future.
