We would rate the installation and service provided as top rate, and at a very competitive rate. We are really pleased with our PV and battery setup and would happily recommend Kierran and his team, who provided an exceptional service.

Kierran rescued us from the results of a very poor installation of solar batteries (from another company). He responded quickly and arrived the next day. He showed excellent understanding of the issue and worked efficiently to rectify it. By the time he left the system was visibly up and running again, and I felt I knew a great deal more about how it worked. I won't hesitate to call on Kierran again if there are any future problems, or if we wish to extend or upgrade the system.
