Behind seemingly unrelated issues such as delamination at the edges of photovoltaic modules, continuous cracking of glass panels, and battery arrays failing due to shading, all point to the same source - structural issues that were overlooked in the design of photovoltaic power plants.
Industry data in recent years shows that the "failure rate of appearance inspection is on the rise", with a considerable proportion of failures stemming from structural issues. Meanwhile, flexible photovoltaic technology has made breakthrough progress, and its unique structural advantages are receiving increasing attention.
The frequent occurrence of delamination issues at the edges of photovoltaic modules is no longer a trade secret. Independent industry tests have shown that "such delamination defects are becoming the primary cause of module failure.".
This delamination phenomenon typically occurs after testing in a hot and humid environment, especially in the edge areas of glass components. When bubbles form at these edges, it indicates that the adhesive force between the encapsulation material and the component surface has been lost.
The presence of bubbles is not merely an aesthetic issue; it poses a direct threat to the safe operation of the entire photovoltaic system. Air is not an electrical insulator, and delamination directly leads to a reduction in electrical creepage distance. This means that issues such as "inverter electrical insulation failure," "grounding failure, and even module arc fault" are more likely to occur.
The structural issues exposed by rigid photovoltaic modules during long-term service extend beyond delamination. Relevant research indicates that numerous early operational defects exist in many photovoltaic systems.
Hot spots are the most prevalent type of defect, which can lead to localized overheating, thereby accelerating material aging and power loss.
At the same time, the study also documented cases of glass cracking and junction box malfunctions. These issues mostly stem from the inherent limitations of traditional rigid structures, which are unable to flexibly adapt to environmental changes and difficult to effectively alleviate stress concentration.
Unlike traditional rigid photovoltaics, flexible photovoltaics directly address many pain points in traditional designs through innovations in materials and structures. Relevant research has advanced flexible photovoltaic technology from different perspectives.
The designed "tight-loose" dual-layer buffer structure can effectively absorb and release the stress generated during the manufacturing process and bending, while ensuring electronic transmission.
This structure enables flexible solar cells to maintain a high initial efficiency even after multiple bending tests and extreme temperature cycling tests.
Meanwhile, the study also documented cases of glass cracking and junction box malfunctions. These issues mostly stem from the inherent limitations of traditional rigid structures, which are unable to flexibly adapt to environmental changes and struggle to effectively alleviate stress concentration.
Flexible supports are fundamentally changing the construction concept of photovoltaic power plants. Traditional rigid supports rely on large-scale site leveling, while flexible supports adopt a prestressed design that can adapt to various complex terrains and extreme climates.
The flexible support system has successfully undergone rigorous vibration and hidden crack tests, and has demonstrated outstanding performance in strong wind and hail experiments. In various practical application environments, the support has continuously withstood multiple extreme weather challenges.
The real advantage of flexible photovoltaics lies not only in its materials and technology, but also in its adaptability to diverse application scenarios. Flexible photovoltaics can be applied to various surfaces, such as curved roofs and other irregular structures.
For the "fish-solar complementation" project, flexible supports can provide sufficient clearance to achieve non-interfering coexistence of "generating electricity above and raising fish below".
In composite applications such as "photovoltaic + agriculture" and "photovoltaic + sand control", flexible technology has demonstrated superior adaptability compared to rigid solutions.
When choosing flexible photovoltaics, one should not only focus on the initial investment savings, but also consider the comprehensive benefits throughout the entire life cycle of the power station. Structural issues that are overlooked during the design phase often become a huge burden for later operation and maintenance.
Flexible photovoltaic systems can significantly reduce maintenance needs caused by structural failures. The flexible design can notably mitigate risks posed by shading, physical impacts, and thermal stress, issues that often lead to hot spots, glass cracking, and delamination in traditional rigid components.
The photovoltaic industry is transitioning from "rigid conquest" to "flexible coexistence", with flexible photovoltaic technology addressing structural issues that have long been overlooked in traditional designs. In the future, more and more irregular building surfaces and complex mountainous terrains may be illuminated by flexible photovoltaics.
Those sites that were previously deemed "unsuitable" for installing photovoltaic systems are now experiencing new vitality thanks to flexible technology.
