Overview:
Byers recently completed phase two (phase one was completed in 2013) of a solar project at a home furnishings distribution center in Perryville, MD. All work was conducted on a 42′ high roof and all components were set utilizing Byers lifting equipment. This operation was closely monitored throughout the project to ensure the heavy traffic in and out of the facility was not interrupted.
Phase One consisted of a 2.67 MW system with 18,576 thin film 144 watt panels installed over a 20 acre roof. This system produces 1,900 amps at 480 volts.
Phase Two consisted of a 2.2 MW system with 7,337 polysilicon/multicrystalalline 300 watt panels installed over a 15 acre roof. This system produces 1,600 amps at 480 volts. The delta was injected back into the electrical grids and metered accordingly for both systems. The following installations completed the project to allow the system to be fully operational:
Phase One:
- 36 roof mounted combiner boxes
- 15,960′ of aluminum cable tray with covers for the home run feeder cables and string wires ranging from 6″ to 36″
- 600,000′ of #10 1,000 volt string wires
- One 18’x35′ concrete pad with privacy fence using approximately 50 yards of concrete
- Four 560kw inverters
- Two 1,000KVA 3 phase 230v to 480v boosting transformers between the inverters and the indoor solar gear
- One 4,000 amp indoor switch gear to connect the solar generated power to the utility power
- One complete monitoring weather station on the roof with fiber and data cables to monitor production
- The existing service was rerouted through a custom made concrete vault, installed between the existing switch gear to the solar gear, for the cabling to travel back and forth between the two switch gears
- 180,360′ of wire ranging between 1/0 and 4/0 for the DC feeder cables
Phase Two:
- 24 roof mounted combiner boxes
- 8,300′ of aluminum cable tray with covers for the home run feeder cables and string wires ranging from 6″ to 48″
- 350,000′ of #10 600 volt string wires
- One 18’x33′ concrete pad with privacy fence using approximately 42 yards of concrete
- Three 560kw inverters
- One 4,000 amp indoor switch gear to connect the solar generated power to the utility power
- One complete monitoring weather station on the roof with fiber and data cables. This system was then connected to the existing system installed during phase one
- The existing service was rerouted through a custom made concrete vault, installed between the existing switch gear to the solar gear, for the cabling to travel back and forth between the two switch gears
- 115,000′ of 600mcm wire sixed for the DC feeder cables
- 7,337 panels on the racking
- 10,970 Polar Bear racks for panels
- 27,993 8″x16″x4″ thick freeze resistant concrete blocks as the weighted ballast system
- 29,348 Ground Claw grounding clips to mount panels to the racking
Consistent with the IKEA commitment to sustainability, we recently installed two large solar PV arrays on the roof of our 1.8 million-square-foot distribution center in Perryville, MD — making the combined installation one of the largest rooftop solar arrays in the country.Phase One consisted of approximately 18,000 panels producing 2.7 megawatts of power and Phase Two consisted of approximately 7,300 panels producing 2.2 megawatts of power. When Phase Two bids were received, it was clear Byers provided the most accurate and comprehensive proposal. With the confidence of IKEA and our solar integrator, Byers was selected as the sole contractor for both phases and was instrumental in keeping the project on track, on budget and completed with the highest degree of workmanship and professionalism from inception to completion. Many times during the project, Byers went above and beyond what was expected in order to keep the project moving in the proper direction.In my 25 years of experience as a Facilities Manager, Byers Industrial has made the short list of extremely capable, competent and trustworthy contractors.
