Public Utility Solar Energy in Tuscon, AZ

Tuscon, AZ – 20MW

This project was developed by Sun Edison.  Our installation team handled several electrical components of the project, which included wiring combiner boxes, troubleshooting string wiring, performance testing of solar strings to specifications, and general electrical tasks throughout the site.

The crews wired approximately 254 combiner boxes (24-string) at 15 minutes per unit.  Personal Protection Equipment (PPE) was utilized as soon as the wires were energized. Lock-out and tag-out procedures were used to identify energized components and increase safety precautions per OSHA requirements.

The project was completed on-time and on-budget.
