Over the course of the day, the sun moves though the sky. A photovoltaic system which is constantly pointed at the sun can absorb more energy, and therefore generate more electricity, than stationary systems. The DEGER-Traker is an active tracking system that constantly moves the modules in the optimal direction to maximize energy generation. This solar tracking improves electrical generation by 35 to 45 percent over stationary arrays. We offer both single and double axis tracking systems from DEGER. The TOPtraker, a single axis active tracking system, is suitable for applications on flat roofs, façades, and open fields
