In June 2010, with the assistance of funding from the US Department of Energy and the Omaha Public Power District, Creighton University is deploying a variety of solar and wind energy collection systems on the grounds of the main campus.  Altogether, these collectors are capable of generating approximately 120 kW of clean, renewable energy.  The collectors and associated power inverting electronics include a broad spectrum of commercially available architectures chosen as part of student-oriented research project to evaluate the performance of these renewable energy systems in the climate of Nebraska.

Kiewit Fitness Center Rooftop: 20.5 kW 

Mounted with a southern exposure and a 5 degree inclination, this collection system consists of multiple strips of flexible photovoltaic laminate arrays totaling 143 individual panels (each approximately 23 sq. ft).  The laminate is manufactured by Uni-Solar (PVL-144) and the system is partitioned into three sections each of which is converted to ac power using three power inverters manufactured by Fronius (IG-Plus 7.5-1 Uni Inverter).

Lied Performing Arts Center Lawn: 8.2 kW

Placed strategically around the southwest corner of the building to take advantage of turbulent air flow, are four vertical axis wind turbines manufactured by Miriah (Windspire).  Each turbine has a capacity of 1.2 kW and uses an integrated power inverter.  Also located at this site is a Watt-Sun (AZ-225) solar tracking array composed of 16 Sanyo (215N HIT) panels each connected by Enphase (M210) micro inverter with net power 3.4 kW.

Cuming Street Parking Lot: 85 kW


This site contains the broadest variety of solar collection architectures and power inversion technologies and, together with an integrated weather monitoring station, serves as the main laboratory for student research activities.  Located at this site are:

  • One Watt-Sun (AZ-225) tracking array composed of 16 Sanyo (215N HIT) panels each connected by Enphase (M210) micro inverter with net power 3.4 kW
  • 6 Sanyo (215N HIT) panels (each 13.5 sq. ft. area, 215 W) inverted by a Fronius (IG Plus 3.0-1 UniInverter) inverter with net power 1.3 kW.
  • 32 Sanyo (215N HIT) panels inverted by a Fronius (IG Plus 7.5-1 UniInverter) inverter with net power 6.9 kW.
  • 105 Evergreen Solar (ES-A-210) panels (each 17 sq. ft. area, 210 W) inverted by 3 Fronius (IG Plus 7.5-1 UniInverter) inverter with net power 22 kW.
  • 33 Sharp (ND-U224) panels inverted by a Fronius (IG Plus 7.5-1 UniInverter) inverter with net power 1.4 kW.
  • 33 Schott (Poly 220) panels (18 sq. ft. area, 220 W) inverted by a Fronius (IG Plus 7.5-1 UniInverter) inverter with net power 7.3 kW
  • 6 Sanyo (215N HIT) panels each inverted by Enphase (M210) micro inverter with net power 1.3 kW.
  • 60 Sanyo (215N HIT) panels each inverted by Enphase (M210) micro inverter with net power 13 kW.
  • 72 Sharp (ND-U224) panels each inverted by Enphase (M210) micro inverter with net power 16 kW.
  • 72 Schott (Poly 220) panels each inverted by Enphase (M210) micro inverter with net power 16 kW.
