Leading Tracking Technology

sonnen_system

Our dual-axis photovoltaic tracking systems align the solar panels to the optimum angle to the sun for power generation. This process allows the energy usually generated using static photovoltaic panels to be increased by as much as 45%. Optimal alignment is made possible by a precise astronomical control mechanism which can plot the course of the sun from any geographical location at a given time of the year. sonnen_system trackers have repeatedly proven that they can consistently deliver improved levels of photovoltaic power generation in a wide range of conditions.
