Hawaii Pacific Solar (HPS) has installed photovoltaic (PV) systems at three additional Oahu public schools: Waianae Elementary, Waianae Intermediate and Leihoku Elementary. Each of these Department of Education schools is estimated to save from $600,000 to $745,000 over the 20-year life of the system.

“We are encouraged by Hawaiian Electric Company’s movement on its agreements so the Department of Education can realize the savings from solar power. We are nearing the completion of our contract and expect to have PV installed at the last two schools, Aiea Elementary and Maile Elementary, by the end of the year,” said Bob Johnston, president and CEO of HPS.

Under a Power Purchase Agreement awarded to HPS by the Department of Education (DOE), in total HPS will install solar panels at 45 Oahu and Kauai schools whereby the system is owned, operated and maintained by RC Energy of Denver Colorado. The installations are at no cost to DOE. Additionally, HPS is giving each school lesson plan materials on solar energy, a sun safety program and a flat screen monitor for students to do real-time monitoring of the power being generated and the amount of carbon reduction as a result of the solar panels.

The PV systems will each prevent close to 300,000 pounds of carbon dioxide from entering the atmosphere — equivalent to the CO2 emissions from 15,000 gallons of gasoline or from 300 barrels of oil.
