Rosendin provided full turn-key engineering, procurement and construction services for the installation of solar photovoltaic energy systems at the Cascade Solar Project located in Joshua Tree, CA. The project is a 24MW DC Flat Panel System (SunEdison 315W & 330 Panels) installed on a SunEdison Single Axis Tracker with a 150 acre foot print.

The start date of the project was scheduled for July 8, 2013. Multiple project difficulties resulted in a one month project delay. Prior to construction, tortoise fencing was installed around the site to protect the indigenous Desert Tortoise and other wildlife. The project was also being constructed on an old Indian Campground which required archaeologists and geologists on site at all times. In addition, the permits were delayed which resulted in the project schedule being shortened to three months. Active work was only allowed between the hours of 7a and 7p, six days a week. The Arizona Desert Monsoons - with rain, wind, and dust - caused project disruptions and the Hi-Voltage transformers did not arrive on-time.

With the project delays and unavoidable circumstances that were encountered, our team managed to save the client a considerable amount of time and money on the Cascade Solar project. Installation was completed in 66 working days, a notable achievement in the solar industry, and the project was fully operational on December 12, 2013, with a minimal punch list of five items. In addition, Rosendin built the Substation for the project in record time.
