“The 1.2 MW Westar project design used a Solar FlexRack tracking system. This was Brandt’s first experience installing a Solar FlexRack tracking system. NESCO’s experience with the Solar FlexRack system played an important role in completing the installation within a narrow time frame. Their ability to use minimal professional staff to manage local labor helped alleviate customer concerns that the project would be installed by an out of state contractor. NESCO was very supportive in assisting other trades with questions or concerns regarding the installation of the system. Their flexibility in spite of inclement weather delays made this project a success. We look forward to working with NESCO on future projects.”
“Working with NESCO makes my job easy. They are a great solar installer. They take all parts of the construction of solar arrays with great care and understanding of what my company is looking for. I would recommend them to anyone in the solar field.”
“NESCO is our first choice to work with on any ground mount projects. Their quality of work is unparalleled, but what keeps us coming back is the communication and collaboration. NESCO anticipates problems and helps to develop solutions; they are diligent with daily reports and RFIs; and they have safety and schedule top of mind. The field crew at NESCO is very experienced and easy to work with. NESCO understands that building a solar project involves multiple trades working in the same area, and they act in a very collaborative way instead of competing for workspace.”
