Deger Solar PV Trackers

Single and Dual Axis solar trackers

A solar tracker automatically follows the sun during the course of a day and throughout the seasons of the year.  They generate around 30-40% more energy than a conventional fixed array.  Areas that are exposed to high levels of sunlight or for applications such as solar pumping then trackers are considered the ideal solution.  It may even be worthwhile to consider a tracker when the cost of adding additional solar panels is outweighed by the increase in power obtained from a tracker, thus making them very cost effective.
Trackers also offer additional advantages over fixed array systems as then can capture more of the available light during day-to-day operating thus making them very efficient. 

Below is an example of a Deger 3000NT tracker with Sanyo 240 HDE4 solar modules.

DEGEREnergie tracking systems are fastening systems for photovoltaic modules. They constantly adapt the angle of PV modules to face the sun, so that the irradiation angle and the light intensity remain constant and a maximum of electrical energy can be generated. This not only helps to exploit every minute of sunshine but also to make the best use of diffuse light – all year round. This leads to an added solar energy yield of 20 – 25% for single-axis, and 35 – 45% for dual-axis tracking systems. The result is increased efficiency and thus shorter amortization times or higher profits. DEGER tracking systems pay!
There are different types of tracker systems available - PASSIVE TRACKING, ACTIVE TRACKING and SINGLE AND DUAL AXIS TRACKING. Single axis tracking is easier to implement as the system can either track the the daily path of the sun or its yearly path. Solar trackers are ideally suited to water pumping applications as they can be utilised to to increase the amount of water pumped during the course of a day. As the tracker can be set to dawn and dusk operation this will significantly increase the amount of water pumped during a single day.
Solar trackers use an optical, solid-state sensor to align the modules to the arc of the sun and sun sensors calculate the amount of sunlight falling on the array thus allowing the solar tracker ensure a uniform spread of sunlight on the array.
At night the solar tracker moved into a horizontal position in order to maximise output from the diffused conditions and moves back to the sunrise position on daybreak.
