sbp sonne was commissioned to analyse the PV tracker designed by STI Nordland for its load-bearing capacity and functionality for a solar project in Spain.
For this purpose, reference calculations for the different tracker types had to be prepared and component verifications carried out. The determination of the wind loads was checked and the wind tunnel tests used were to be analysed for their applicability. The load approaches, based on the pressure coefficients, as well as the dynamic behaviour were evaluated taking into account the natural frequencies and damping ratios. The testing was carried out in accordance with the tried and tested German testing system, which offers reliable control and guarantees independence by applying the dual control principle.
