Solar tracker with battery

The solar tracker is a technical innovation for tracking the sunlight, in order to increase the yield of photovoltaic panels. The productivity gain can reach 40% with a 2-axis tracking system. TRACSOL is a teaching solution for learning this technique. Equipped with 2 axes and 4 cells for automatic sunlight tracking of the sun, it is completely self-contained. No 230V mains connection is required. Only the artificial solar source enabling TRACSOL to be used indoors is powered with 230VAC. The transparent sides of the mechanical box enclosing the two axes provide a full view of the chain drive linkages.
4 BNC fixed on the front of the cabinet allow the oscilloscope reading of the signals generated by the 4 solar cells. The voltage of the solar panels is available on
the two safety terminals. The assembly is mobile thanks to 4 heavy-duty wheels attached under the frame.
