Upgrade Trackers to DEGER MLD

UPGRADE ANY TYPE OF TRACKER TO DEGER MLD TECHNOLOGY

This conversion can be performed to all the existing types of single and dual axis trackers :astronomical type, gps etc.

Your energy production is going to increase from the very next day !

Τhe technical parts of DC trackers come preassembled and are available now.

We design and apply the best technical solution for trackers functioning on AC or with the assistance of hydraulic motors.

By the end of the upgrade procedure you can rely on full technical support from DEGER.

DEGER is the leading manufacturer with the world’s largest product portfolio for single and dual axis solar tracking systems. Its market position is based on the unique, patented “Maximum Light Detection” or MLD technology.

When compared to astronomically-guided dual-axis tracking systems, the DEGERtrackers enjoy a clear advantage. The Zentrum für Sonnenenergie und Wasserstoff-Forschung (ZSW) [=Center for Solar Energy and Hydrogen Research] calculated an increase of around 27 percent for astronomically-guided systems over fixed systems in European latitudes. MLD technology also offers 7% – 8% more energy for solar collectors in comparison with astronomically-guided trackers. Therefore, the energy production is going to increase at this rate from the next day of the upgrade.

Nowadays, over 50 solar installations throughout Europe have already been upgraded followed by a significant number of solar parks owners, who are interested in repowering their energy installations with DEGER MLD technology. Not only their energy production will increase significantly in the most efficient way on terms of energy use, but there will also be many more benefits for them.

A lot of solar parks that are going to be upgraded, happen to be outdated installations of solar trackers based on GPS and Astronomical Equations. The installed systems with astronomical guidance, don’t receive technical support anymore, which is a crucial matter of performance and durability through time. Most of the previous installation companies either have shut down or been inactive for the last years.

Increase your production by upgrading to MLD technologies

How such an upgrade is achieved?

Technically speaking, astronomical type of dual axis trackers consists of azimuth and elevation movement and functions with the help of dc (or ac) and Hydraulic motors. The whole mechanical function is controlled by a relatively complex system of PLC controllers. A main problem is that their maintenance costs a lot of money, thus many times you have to pay a significant amount in order to get a service from the software engineer and manufacturer of the tracker. Once you upgrade your old trackers to DEGER MLD tracking, all these come to an END!

Image on the left shows the control board of an astronomical type – tracker.These complex astronomical control systems can be bypassed and connected with our custom control board on multiple (in this case 2) points, could be in the manual operation sub-system or fully bypass the PLC controller that in most cases exist.

After the technical intervention, control boards of astronomical type- trackers should be connected MLD adaptor board and therefore obey the commands of DEGER MAXIMUM LIGHT DETECTION – DEGER-MLD technology.

In any case the astronomical algorithm is bypassed and MLD active tracking technology will drive the upgraded tracker to optimum yield.

For a 2axis tracker MLD upgrade we also provide you two DEGER MLD sensors, connected with a special DEGER circuit board energy converter towards an adaptor board. The DegerMLD sensors are placed on specific points of the to-be-upgraded-tracker at Azimuth and Elevation orientations so the tracker performs correct “solar tracking” movement.

DEGER equipment, described as above, is connected with ΜLD signal adaptor board. It has 8 control relays and manages to integrate DEGER MLD light detection technology to astronomical control systems.

This kind of tracker upgrade process from astronomical guidance to DEGER MLD technology, took place in Greece. The owner of a solar installation at Inofyta – Voiotia (mainland Greece) turned to DEGER in order to increase the daily yield of its installations. The 2-axis astronomical trackers were lagging behind in the sector of desired productivity .

7% Increase in energy production from day one!

As a natural result, a decision was made to upgrade the sun monitoring system. DEGER gave a completely successful energy solution.

The solar park has an installed capacity of 100 kWp , so as to highlight the difference in energy production, a 13.4 kW tracker has been selected, previously equipped with astronomical detection and shadow control for the afternoon. This unit was removed and replaced with two Deger MLD sensors and a custom, designed by DEGER , control panel.

The absolute success of the upgrade procedure motivated the owner to complete two more upgrades to equal number of astronomical trackers. In total, 3 trackers from the total number of 7 trackers were upgraded to DEGER MLD technology and managed to achieve the desired energy production for the facility.

The solar collectors’ yield from the very next day increased by 7%. (Tracker number 5 with installed DEGER MLD Technology, depicted by red line)

As you can see from the chart below, the upgrade procedure to DEGER MLD tracking technology has been completed for some specific tracker brands. Likewise, we obtain the study and plans, that refer to conversion to our advanced and effective light Detection technology, for even more solar tracking brands.

When owners upgrade their solar trackers to MLD technology, they get to receive the guaranteed technical support DEGER, (technical advice, spare parts etc). This will increase a lot their lifetime span, also meaning that their solar installations will be operational and productive for years to come.
