Installing a photovoltaic (PV) array starts with selecting a suitable mounting structure, which will support the solar panels and place them at an optimal angle to receive sunlight. The choice of mounting structure
Key findings are as follows. Dynamic characteristics of tracking photovoltaic support systems obtained through field modal testing at various inclinations, revealing three torsional modes within the 2.9–5.0 Hz frequency range, accompanied by relatively small modal damping ratios ranging from 1.07 % to 2.99 %.
The software SAP2000 has strong functions, design of the fixed photovoltaic support. Japan. The deg ee of the design angle of PV modules was ×991 mm×40mm. The single photovoltaic array unit was arranged into 4 row s and 5 column s. According to the basic parameters were shown in table 1.
Through processing and analyzing the measured modal data of the tracking photovoltaic support system with Donghua software, the dynamic characteristic parameters of the tracking photovoltaic support system could be obtained, including frequencies, vibration modes and damping ratio.
Even fixed solar array support structures have sofisticated design, that needs to be analyzed and often improved in order to withstand the wind load. The same applies of course to adjustable designs to an even greater extend. The analysis has to be carried out for many wind directions.
The comparison of the mode shapes of tracking photovoltaic support system measured by the FM and simulated by the FE (tilt angle = 30°). The modal test results indicated that the natural vibration frequencies of the structure remains relatively constant as the tilt angle increases.
Aeroelastic model wind tunnel tests The wind-induced vibration response of flexible PV support structure under different cases was studied by using aeroelastic model for wind tunnel test, including different tilt angles of PV modules, different initial force of cables, and different wind speeds.
