Ptolemeo - Model PV50/80 - Dual Axis Solar Trackers
The motion mechanism of the system is based on two axes. It follows automatically the sun's azimuthal and polar movement maximizing solar radiation incidence and thus the electricity production by the photovoltaic panels. The system is driven by the most reliable way: Software using astronomical algorithm is employed to compute the precise position of the sun at any given moment as a function of time, date and latitude. In this way the system cannot be misled by weather conditions (clouds etc) or other interfering factors (artificial lighting etc.). During cloudy weather, it automatically sets itself at horizontal position in order to receive the maximum of the diffuse radiation, minimizing at the same time energy consumption.
Characteristics
The first tracking system to use a specially designed “space frame” (patented OBI 1006740) for the support of the solar panels. It gives unequaled robustness and reliability compared to any other solar tracker even at extreme weather conditions.
Combines electromechanical motion for azimuthal rotation and hydraulic for tilt elevation. Not only one but two hydraulic cylinders are used, ensuring thus enhanced holding torque and especially wide, four-point (not only threepoint)seating.
