Causes of cracking of photovoltaic panels during transportation
This stress can result from manufacturing, transportation phase to the PV site, installation process, or heavy snow and physical damage to the modules. Optimizing these processes can reduce cell cracking; cracks during production are unavoidable. Also, some climate proceedings such as snow loads, strong winds and hailstorms might create some major cracks on the PV modules surface,,. Microcracks refer to the invisible cracks that may be produced in the cell unit that are not easily detectable to the. . Statistics show that almost 5% of panel damages occur during shipping and transportation. The journey of these modules to reach their destination is long. . This paper discusses cracks in photovoltaic cell caused by en-route transportation to customer, often discovered by observing power efficiency reduction in final photovoltaic cell and module products, or outright disruption of electrical generation for that particular solar cell.

How to protect solar panels from damage?
To be on the safe side, collecting data on the journey of solar panels by monitoring the environmental conditions during transit might reveal damage hotspots and also comes in handy during the claims process. Inspect the solar panel before shipping for any apparent damage. Pack your panels vertically.
What are the most common damages to solar panels?
The most common damages to solar panels are breakages and cracks of the solar cells in the modules. Very often, they are visible directly to the human eye. Micro-cracks, however, are so small they are impossible to see with the naked eye. These micro-cracks negatively affect the panel life expectancy and performance in the long term.
Why do PV modules need a homogeneous mechanical load?
Various mechanical stresses can arise in PV modules due to manufacturing processes, transportation, handling during installation, wind, hail, snow, and thermo-mechanical loads. Numerous studies investigate a homogeneous mechanical load according to IEC 61215 which is crucial for the development of novel module designs.
Does A microcrack increase the size of a PV module?
To study the effect of an initial defect, a microcrack of 10 mm was introduced in the central cell of the PV module. As the load increased, the microcrack propagated and eventually at 2400 Pa, the crack length became 3 times larger than the initial one (Fig. 8).
