Overview

ASU's first installation of a solar photovoltaic system (PV) was completed in 2004 on the top level of Tyler Street Parking Structure. The system produces approximately 30 kW of electrical energy and shades 44 parking spaces. It was installed as part of Phase I of the Energy Performance Contract. It is owned and operated by ASU, and its output provides enough electricity to power the daytime lighting in the structure.

During spring semester of 2006, three students from course ATE 550 conducted a survey of 38 Tempe campus rooftops. The survey, led by Professor Harvey Bryan, indicated that 25 of the 38 rooftops were appropriate for some type of PV system. The study indicated a potential for solar production of more than 4 MW on the 25 rooftops. However, since the study did not include all of the roofs and parking structures at the Tempe campus, ASU facilities staff has estimated the total potential of solar energy to be more than 7 MW and will take 3‐5 years to achieve.


In October 2007, ASU initiated plans to install a 150 kW PV system on the roof of Biodesign A and B. This commitment to install the PV system on Biodesign A and B provided the necessary points for the building to receive LEED‐Platinum certification – the first in Arizona.

In January 2008, ASU issued an RFP for solar developers to propose installation of developer‐owned solar systems on ASU’s campuses. This solicitation resulted in ASU executing Master Agreements with three solar developers in June 2008. They are as follows:
SolEquity (Now CarbonFree Technology)
Honeywell
Independent Energy Group (IEG)


For 2009 another developer‐owner, Arizona Public Service Energy Services (APSES), has become an additional solar partner through a shared agreement with the University of Arizona.
