ASU PV systemClient: ViaSol Energy Solutions

Location: Phoenix, Arizona

Lopez Engineering, Inc. (LEI) designed the electrical portion of two separate Photovoltaic (PV) projects for the ASU Campus in Phoenix, Arizona.

The design effort included detailed field investigation to determine existing conditions, view the locations, determine existing service and equipment and to confirm location of the arrays. Project construction documents integrated detailed calculations (voltage drop; load; panelboard; estimated energy generation), site plans, 1-line diagrams, 3-line diagrams, details (equipment installation; dimensioning information; pump wiring diagram), and schedules. The design was based on specific equipment including solar panels, inverters, combiner boxes, UPS, and pump2.

ASU Parking Structure #1 was a 1 MW PV system with 4,320 PV modules, 27 Combiner Boxes, (4) 250 kW inverters and (1) 480/277 V, 1600 A Switchboard. LEI’s design incorporated new POC, (1) 20 kW UPS for tracking system and (18) 1 HP Pumps.

ASU Parking Structure #5 was a 750 kW system with 3,150 PV modules, 19 Combiner Boxes, (3) 250 kW inverters and (1) 480/277 V, 1200 A, Switchboard. LEI incorporated new POC, (1) 20 kW UPS for tracking system and (18) 1 HP Pumps.
