Solar Tracking Concentrator

From Swikipedia

Introduction

A Solar Tracking Concentrator is a solar collector that tracks the movement of the sun. There are two different types, tracking in one axis or in two. One-axis solar tracking and linear focus systems can track the sun only along its angle of elevation over the horizon. In two-axis tracking and point focus systems (parabolic dishes, tower plants with heliostats and solar furnaces) the sun’s rays are always perpendicular to the collector surfaces. Point focus systems are normally only used for applications requiring temperatures higher than 400 °C.

Brief Description

Advantages of Solar Energy:

• The only energy available everywhere and completely free, the solar systems are functional even without any direct sunshine

• The opportunity of absolute energy independence

• Harmless towards the environment

• Up to 50% cost coverage by governmental grants and soft loans

• Investments in solar systems provides valorization of your immovable

• The service life of collectors is of 30 years, significantly longer than with usual heating systems

The solar energy may be relatively well used in the regions not only with the long sunshine period but also in those with higher sea-level altitudes.

Advantages of Solar Tracking Concentrators:

The recent tracking solar concentrator mounted on a mobile stand may double the annual amount of the energy produced in comparison with the configuration, where the solar panels are mounted on stationary stands. An increase by 100% is possible in the dry, sunny climate conditions (for example northern Africa, Arabia, Arizona, western Australia, etc.), an increase by 70% is possible in the conditions of central Europe. The increase in pumping capacity may reach up to 150%.
