A Solar Position Sensor Based on Image Vision [PDF]
Solar collector technologies operate with better performance when the Sun beam direction is normal to the capturing surface, and for that to happen despite the relative movement of the Sun, solar tracking systems are used, therefore, there are rules and ...

Solar position algorithm for solar radiation applications [PDF]
Abstract There have been many published articles describing solar position algorithms for solar radiation applications. The best uncertainty achieved in most of these articles is greater than ±0.01° in calculating the solar zenith and azimuth angles.

A Proposal for a Solar Position Sensor System with Multifiber Optical Cable [PDF]
A solar position sensor is an essential optoelectronic device used to monitor the sun’s position in solar tracking systems. In closed-loop systems, this sensor is responsible for providing feedback signals to the control system, allowing motor ...

Solar Position Algorithm Based on the Kepler Equation
When calculating the position of the sun, earth’s motion can be assumed to be an ellipse if the accuracy of calculation is required to be 0.01 degrees.

Theoretical model of solar incident angle for an optionally oriented fixed flat surface [PDF]
The apparent position of the Sun in relation to any surface is defined by the solar incident angle. The solar incident angle forms the vector of the position of the Sun and the vector of normal to the observed surface.

SUN TRACKING PHOTOVOLTAIC SYSTEM [PDF]
The purpose of this paper is the design and realization of a prototype system for tracking the position of the sun, with two axes of rotation. The operating principle of the device is based on changing the position of the photovoltaic modules in the ...

Fuzzy Logic Controller Application for an Active Two-Axis Solar Tracking System [PDF]
The changes in the intensity of solar radiation cause the electrical power produced by solar panels to be not optimal. The solar panel position control system to the position of the solar is an effort to overcome this problem.
