Abstract:
1. A street light comprising: a pole having a cylindrical section with an outer surface having a circumference; a flexible panel of amorphous photovoltaic material connected to said outer surface so that the flexible panel curves at least 225 degrees around the cylindrical section; a light comprising a plurality of light-emitting-diodes (LEDs), wherein the light extends from an upper region of said pole; at least one battery operatively connected to said flexible panel so that, when sunlight hits said flexible panel, resulting electrical energy charges said at least one battery; and a controller operatively connected to said at least one battery and comprising electronics adapted to control charging of said at least one battery by the flexible panel, and also to control discharging of said at least one battery to light said LEDs, wherein said controller is adapted to control minimum battery voltage of said at least one battery by dimming said LEDs during at least a portion of nighttime to prevent excess battery drain.
