Benefits of technology

[0012]The solar array tracker controller of the present invention utilizes a processor programmed with the above-described algorithm for accurately predicting the location of the sun based on the date, time of day in hours and minutes, local latitude and local longitude. The program takes into account the elliptical orbit of the earth around the sun, which changes slightly over time.

Problems solved by technology

The processor utilizes the data to calculate the azimuth and altitude of the sun for every minute of the day and issues control signals that cause motors to move the device to the calculated angles.
Additionally, none describe a remote interface to the Internet for remote access to the controlling device.

Embodiment Construction

[0033]Referring to FIG. 1, wherein like reference numerals refer to like components in the various views, there is illustrated therein a new and improved solar array tracker controller, generally denominated 100 herein.

[0034]FIG. 1 illustrates a preferred embodiment of the solar array tracker controller 100, and shows that the system comprises a micro-processor / controller 110 having an integral operator interface 120 with an LCD display and a keypad for entry of local data. An exemplary system is the Z-World OP6800, which is a relatively low-cost, C-programmable operator interface and single-board computer with industrialized I / O, a graphic LCD, and a keypad. It includes an integrated control, display, and networking capabilities via Internet / Ethernet or serial communications. This processor includes memory for storing a program including a mathematical algorithm that accurately determines the location of the sun based on local data, such as the date, time of day in hours and minute...

Abstract

A solar array tracker controller including an operator programmable micro- processor electronically connected to the drive motors in a solar panel array or other solar device array. The processor is user programmable and includes memory for storing a software program which includes an algorithm that determines the precise location of the sun relative to the array based on the local data input into the processor A GPS sensor and interface may be provided to obviate the need for local

Description

BACKGROUND OF THE INVENTION[0001]1. Technical Field[0002]The present invention relates generally to solar array tracker controllers, more particularly to a solar array tracker controller which utilizes inputs of the local latitude, longitude, universal time and software incorporating a mathematical algorithm that calculates the optimal positioning of the solar array and initiate movements to achieve the optimal positioning.[0003]2. Background Art[0004]Automated solar tracker controllers are widely used to optimize positioning of solar panels. Solar energy collectors perform most efficiently when the incident rays of the sun are perpendicular to the absorbing surface. And because the position of the sun is constantly changing in relationship to the earth, it is necessary to continually reposition the absorbing surface of solar panels to maintain the most advantageous, perpendicular angle of incidence to the sun's rays. Various solar collector drive mechanisms and tracker controls hav...
