Washington State University Solar PV

LOCATION: Pullman, Washington
CLIENT: Washington State University – Pullman, Washington
DELIVERY METHOD: Design-Bid-Build (DBB)
SERVICES PROVIDED: Electrical System Design

DESCRIPTION: In 2015, WSU became part of a U.S. Department of Energy (DOE)-sponsored project to research, develop and demonstrate technologies needed to create “smart” buildings, campuses and cities to better manage energy usage. Led by Pacific Northwest National Laboratory (PNNL) and including the University of Washington (UW), the pioneering regional partnership brings the three campuses together to demonstrate transaction-based energy management for the first time, testing the large-scale use of transactive controls involving multiple buildings and devices. The transactive idea combines financial signals and control techniques to shift energy usage in devices, buildings and campuses.

As part of the project, WSU researchers will install solar panels on the Pullman campus for the first time and integrate them into Pullman’s “Smart City’’ test bed and WSU’s microgrid system. The WSU researchers will be showing how the WSU Pullman campus can power critical city infrastructure in the event of a power outage.

The solar array communicates automatically with generators at WSU as well as with a unique, one megawatt energy storage battery in Pullman. The campus system communicates automatically with electric meters at both the PNNL and UW campuses.

The solar array consists of a 33.66 kWdc rooftop mounted system, and a 48.96 kWdc ground mount system, which also includes a 6.1 kWdc student demonstration system. Installed system size was 82.62 kWdc with capacity for an additional 30.6 kWdc.

Unitarian Universalist Church Solar Photovoltaic (PV) System

Unitarian Universalist Church Solar Photovoltaic (PV) System

DESCRIPTION: PCI was approached by the Chairman of the Church’s Solar Committee to discuss the design and construction of a large roof mounted Photovoltaic System (PV) to help the Church realize their renewable energy goals. The Solar Committee had been working with several other local engineers and contractors in the area to help build momentum for the project within the congregation. PCI was committed from the start to explore variations of system sizes and methods for maximizing the power production of the system while maintaining a competitive proposal which made the project financially feasible.

The Church had originally raised money to complete the solar array through donations made by members of the congregation but then soon realized that a partnership with Washington Based Non-Profit Sustainable Works would allow them access to financing options to increase the size of the solar array. Sustainable Works was able to secure additional financing for the project while taking on the role as the non-profit general contractor.

At the time, this installation represented the largest Church based photovoltaic (PV) solar array in Washington State.

This project consisted of adding 18.75kW of roof mounted solar photovoltaic panels. The installation included 75 SolarWorld 250W panels along with individual Enphase M215 micro inverters for each panel.
