Introduction

Let's start!

What's a solar Tracker?

A solar tracker is a device for orienting a day lighting reflector, solar photovoltaic panel or concentrating solar reflector or lens toward the sun. The sun's position in the sky varies both with the seasons (elevation) and time of day as the sun moves across the sky. Solar powered equipment works best when pointed at or near the sun, so a solar tracker can increase the effectiveness of such equipment over any fixed position, at the cost of additional system complexity. There are many types of solar trackers, of varying costs, sophistication, and performance.

Nowadays the development of the solar radiation conversion systems is focused mainly on aspects related to materials development and solar energy conversion processes. In the design process of the solar trackers the input data is the direct solar radiation that may be converted in Thermal energy (by using solar collectors) or electrical energy (by use of the photovoltaic panels)

The competitiveness of the solar energy conversion system on the market deals with their efficiency and an alternative solution for improving their efficiency is the use of the tracking systems.

According to the scientific literature, by increasing the incident radiation rate with solar trackers, in order to maximize the degree of direct (and diffuse) solar radiation collection, the efficiency of the solar radiation conversion systems may be increased up to 50%
