Solar streetlights in Nakolo



http://www.thebatteryclinic.co.nz Solar Streetlight. This video shows some of the 13 solar streetlights installed in the village of Nakolo in the friendly island of Tonga. Lights come on at night for 10 hours from 1 X 20 watt HID lamp and turn off automatically at daybreak. One panel provides enough power to light the lamp all night. 65 ah battery placed in the box on the pole.
