    What our clients say

    Our experience we have with DNX Energy has been nothing short of fantastic. The advice, the standard of the equipment, the installation (personel and procedure) and the overall performance of the system has been absolutely first class. In addition, DNX has followed up with service and advice of a very high standard. I would definitely deal with them again and recommend them to anyone who has been thinking about a solar system but hasn’t known who to trust!

    I have just had a 6.5 kW System installed and am very happy with all aspects of project. Having a very Modern House I was concerned that none of external aesthetics of the building would be affected. A lot of adjustments and alterations were required and this was carried out without any fuss. The system is working over and beyond expectation – producing more than anticipated. A good indication of the quality of service is the ‘after service‘ aspect of a job. Here we were followed up and checked up on to make sure we were happy and all was working as it should be. DNX proved very accessible and sincere in there efforts to produce the outcomes promised.

    After some months of researching what is available in the PV world, I chose DNX Energy because they supply quality components and have an unhurried and genuine attitude. They installed a 3.5 kW system using German made panels and Inverter. Many thanks for the great PV system; the guys did a fantastic job installing it, and were very friendly and helpful. Thanks to Igor for his patience with my questions and permutations, and for not giving me the “hard sell” at any time. One of the main reasons for going with DNX Energy was the unhurried respectful way they went through the process. DNX Energy is five star company.
