A solar-powered street lighting system includes a flexible panel of amorphous photovoltaic adhesively connected to the outside surface of a light pole, at least one battery to be charged by the flexible panel, and an LED light fixture extending from the upper region of the pole. A controller controls the charging of the battery by the flexible panel, the battery powering the LED light fixture, and a minimum battery voltage by dimming the LED light fixture during at least a portion of nighttime to prevent excess battery drain.
