Maui Waena Intermediate School

Maui Waena Intermediate School is the 17th school to receive a Sun Power for Schools photovoltaic system. A photovoltaic area lighting system was installed on the concrete wall and fence surrounding the paved play court on March 26, 2002.

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.

System details:

• 65-watt multi-crystalline solar panel (mounted to concrete wall)
• 80 amp-hr sealed gel battery; 5-day autonomy (mounted to concrete wall)
• Charge/light controller (light operation: 6 hours after dusk and 2 hours before dawn)
• Flood light fixture with 24-watt compact fluorescent lamp (mounted to top of fence support pole)
