Palmdale, CA – 2MW |

Although this was our installation team’s first large scale utility project, it was completed on time and under budget. The beginning of the project required working with the civil subcontractor to coordinate the underground electrical and racking installation. Daily meetings and project coordination were critical so that trackers could be installed while pile driving continued to minimize down-time and interruptions. The electrical build-out required low voltage DC (under 1000VDC), medium voltage to the utility at 14.5kV, equipment pad construction and installation of inverters, transformers and switchgears. Additional work also included the telecommunications underground and infrastructure with AT&T. Our team’s in-house crews minimized unnecessary cost mark-ups to our customers.

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. System DetailsNumber of panels: 83,500 Lifetime Environmental Benefits

This project’s design, scope, and access to local resources were similar to the Palmdale solar farm. Our installation team needed to be especially efficient with the allocation of labor to meet the installation timelines and quality expectations. The job scope also included the interconnection build-out, including underground, a power pole, switchgear, and a 38kV gang switch.
The electrical work was sequential and organized: mounting combiner boxes, grounding solar modules and equipment, pulling home runs, mounting inverters & transformers, installing the switchgear and the power pole, pulling & terminating underground Medium Voltage cable, pulling and terminating all low voltage cable from combiner boxes, inverters, and secondary stages of the tranformers, completion of the communication & weather station equipment, and finally, connecting PV strings and energizing the entire site on both the DC and AC sides of the inverters.
The project materials included polycrystalline panels and single axis trackers. System DetailsNumber of panels: 8,300 Lifetime Environmental Benefits
