6 FAQs about [Optimization of photovoltaic support purlins]

How to optimize a photovoltaic plant?

The optimization process is considered to maximize the amount of energy absorbed by the photovoltaic plant using a packing algorithm (in Mathematica™ software). This packing algorithm calculates the shading between photovoltaic modules. This methodology can be applied to any photovoltaic plant.

What is the tilt angle of a photovoltaic support system?

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.

How many pillars does a photovoltaic support system have?

The tracking photovoltaic support system consisted of 10 pillars (including 1 drive pillar), one axis bar, 11 shaft rods, 52 photovoltaic panels, 54 photovoltaic support purlins, driving devices and 9 sliding bearings, and also includes the connection between the frame and its axis bar. Total length was 60.49 m, as shown in Fig. 8.

Does a tracking photovoltaic support system have finite element analysis?

In terms of finite element analysis, Wittwer et al., obtained modal parameters of the tracking photovoltaic support system with finite element analysis, and the results are similar to those of this study, indicating that the natural frequencies of the structure remain largely unchanged.

What are the dynamic characteristics of photovoltaic support systems?

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 %.

What is the modal damping ratio of a photovoltaic support system?

Additionally, consistently low modal damping ratios were measured, ranging from 1.07 % to 2.99 %. Secondly, modal analysis of the tracking photovoltaic support system was performed using ANSYS v2022 software, resulting in the determination of structural natural frequencies and mode shapes.
