This document serves as the Assembly and Operating Manual for DEGER D25H, D60H, D80, and D100 solar tracking systems, providing comprehensive instructions for their installation, operation, and maintenance.
Function Description
The DEGER systems are designed for the tracking of photovoltaic modules, ensuring optimal solar energy capture. These systems are not intended for any other use, such as concentrated modules, mirrors, or other purposes. They are suitable for outdoor installation and building integration, maximizing energy yield by precisely orienting solar modules towards the sun. The systems utilize a patented control and patented mechanical design to achieve maximum efficiency, resulting in a significant increase in yield. The MLD-control (Maximum Light Detection) is a key component, designed to operate with maximum efficiency and to perform only such movements that will result in an immediate increase in yield.
