Rowena 3 kw Off-Grid Solar System

We were approached by Rowena to install a solar power system to further their goals of being self-sustainable energy wise and reduce her dependence on Noreco. During the consultation we identified the size of the system she would require also that it would be necessary to have a battery system to meet here goals. We recommended, and she went ahead with a 3 kw off-grid system with 4 battery array for energy storage. After installation of this 3kw off-grid system, the client walked away satisfied and confident she made the right choice going with DPX Solar!

Don’t forget that DPX is more than just solar. we are also a full service construction company with many more services to offer.
