Sun Power for Schools

Iao Intermediate School

Iao Intermediate School is the eighteenth school to receive a Sun Power for Schools photovoltaic system. A photovoltaic area lighting system was installed on Building I by Maui Electric personnel on June 13, 2003.

The system consists of a solar panel, an enclosure that houses a battery and a solar lighting controller, and luminaire. The solar panel charges the battery with DC electricity during the day and the battery powers the luminaire at night. The solar lighting controller regulates battery charging/discharging and controls lighting operation.
