Pole-mounted power generation systems, structures and processes

Abstract

Solar power systems and structures are mountable to a power distribution structure, e.g. a power pole or tower, which supports alternating current (AC) power transmission lines. An exemplary power generation structure is fixedly attached to and extends from the power distribution structure, and comprises a mounting rack. A solar array, comprising at least one solar panel, is affixed to the mounting rack. A DC to AC invertor is connected between the DC outputs of the solar array and the AC power transmission lines. The length of the solar array is generally in alignment with the power distribution structure, and the width of the solar array is greater than half the circumference of the power distribution structure. The mounting rack and solar array may preferably be rotatable, such as based on any of location, time of day, or available light.
