Solar Panel Tracking and Mounting System

Abstract

A method for tracking solar panels includes the steps (a) beginning a tracking cycle substantially at sunrise with adjacent tilting panels all horizontal, (b) tilting the adjacent panels in unison in a first angular direction toward the rising sun at a tilt rate that just avoids shading of adjacent panels, (c) reversing direction of panel tilt at a point that the panels reach either a maximum tilt limited by mechanical design, or the panel surfaces are orthogonal to the rising sun, (d) tilting the adjacent panels in a second angular direction, following movement of the sun and keeping the surface of the panels at right angles to the sun's position, until a point is reached that shadowing is imminent from the angle of the setting sun, and (e) reversing direction of panel tilt again to the first angular direction, adjusting tilt as the sun sets to avoid shading until the panels are again horizontal.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The present invention claims priority to a U.S. provisional patent application Ser. Nos. 61 / 217,794, filed on Jun. 3, 2009, 61 / 268,237, filed on Jun. 9, 2009, and 61 / 311,745, filed on Mar. 8, 2010, disclosures of which are incorporated at least by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention is in the field of solar tracking systems and pertains particularly to methods and apparatus for tracking the sun using at least one tilt angle while minimizing any shadowing on adjacent solar collection panels.[0004]2. Discussion of the State of the Art[0005]In the field of solar tracking systems, there are system that can produce substantially more energy (watts / panel) compared to fixed arrays of the same type and capacity by enabling tracking of the sun. This difference is most pronounced for those using crystalline silicon PV technologies, where a single-axis tracking systems could add up to 30% m...

AI Technical Summary

Benefits of technology

[0009]Every solar system is propelled by the suns rays, one by-product of which is an abundance of stored energy that can be utilized directly. Most such systems employ solar panels and tilting means to minimize angle of incidence (AOI) thereby increasing energy savings.

[0010]The present inventor realized in an inventive moment that if, during solar tracking, modular solar collecting devices could be caused to track the sun in unison using both synchronous and counter synchronous tracking such that by one or more pivot ...
