Sun Power for Schools

McKinley High School

On January 23, 1998, McKinley High School became the third Oahu school to receive a sun-powered rooftop solar system from the Sun Power for Schools program. The system was set up on the school's gymnasium roof.
Original system details:

  • Two kilowatts (kW) rated peak
  • Eight 4x6 foot panels, weighing 110 pounds each (Manufacturer: ASE, Type: ASE-300-DB/50-285)
  • DC and AC disconnection switches
  • Omnion inverter to convert DC current to AC
  • Autotransformer
  • Data acquisition system (Data collection can be monitored and analyzed by students as part of integrated renewable energy lessons)

In April 2004 the Omnion inverter was replaced with a SunnyBoy 2500U inverter. On October 5, 2011 the system was retrofitted with eight new PV panels to replace the older system.
Current system details:

  • 2 kilowatts (kW) rated peak
  • Eight Suntech Pluto245-wde panels
