6 FAQs about [Photovoltaic module mechanical load support]

What is cable-supported photovoltaic (PV)?

Cable-supported photovoltaic (PV) modules have been proposed to replace traditional beam-supported PV modules. The new system uses suspension cables to bear the loads of the PV modules and therefore has the characteristics of a long span, light weight, strong load capacity, and adaptability to complex terrains.

Are photovoltaic modules subject to dynamic loads?

Volume 44, article number 87, ( 2022 ) From manufacturing to field operation, photovoltaic modules are subject to dynamic loads. Cyclic load produces dynamic bending moments with tensile and compressive stresses within the solar cells and interconnects.

What is a PV support structure?

Support structures are the foundation of PV modules and directly affect the operational safety and construction investment of PV power plants. A good PV support structure can significantly reduce construction and maintenance costs. In addition, PV modules are susceptible to turbulence and wind gusts, so wind load is the control load of PV modules.

How many PV modules are in a cable-supported PV system?

The new cable-supported PV system is 30 m in span and 3.5 m in height and consists of 15 spans and 11 rows. The center-to-center distance between two adjacent rows is 2.9 m. There are 25 PV modules in each span, which are divided into 5 groups. Each group has 5 PV modules, and the gap between two groups is set at 10 cm.

Does cyclic mechanical load affect PV module performance?

Experimental results prove that the support significantly enhances the performance of the module against power loss. The findings of this paper inform on the initial stage of PV module’s degradation during cyclic mechanical loads and provide a descriptive report of the critical areas that are subjected to cracking.

How is a PV module fixed?

The PV module is fixed on Cables 1 and 2 by using back-fasteners. The maximum stress is calculated as 6.60 × 10 7 N/m 2 at the four nodes connecting the load-bearing cables and the PV module. Similar results are observed in Case 180°, as shown in Fig. 13 (b).
