often deployed. Failure rates in harsh environments are increasing nowadays due to the push for cheaper modules, which has driven the trend toward larger PV modules with thinner glass, cheaper encapsulants and backsheets, and reduced frame thickness. glass, improved frame geometries,micro-crack-resistant interconnections, and advanced encapsulants like POE or silicone. Very often, mitigation measures aimed at addressing one issue can inadvertently exacerbate another, making it essential to conduct conditions to identify the most effective solution. Experience with climate-optimised PV modules is stil limited, requiring more field data and lessons learned to be exchanged within the PV community. capacity in land-constrained regions, enabling dual use of water surfaces. However, uncertainties remain regarding yield modelling, degradation mechanisms, and the development of cost-efficient O&M very promising. In order to accelerate the adoption of FPV, more work is needed to assess environmental impacts, address complex or missing regulatory frameworks, and reduce cost barriers. As extreme weather events become more frequent and severe, and global PV capacity continues to grow rapidly, understanding and addressing weather-related risks is increasingly important. The most Improvements and automation of monitoring and O&M practices, cyclones, convective storms and hail, snowfalls, dust and sandstorms, combined with more open sharing of data, can reduce costs during heatwaves, floods and wildfires. The events cause both catastrophic damage, such as the destruction of modules or mounting structures, reliability, ultimately leading to faster scalability. can lead to accelerated performance degradation over time. Energy Yield, Reliability, and Maintenance. → See more PVPS publications about floating PV, performance, As global PV deployment accelerates - driven by falling costs, advances in technology, and urgent climate goals - installations are increasingly located in challenging environments such as deserts, tropical regions, areas prone to hail damages, and cold, snowy areas. These regions to PV system durability and performance, making tailored design and Most PV plants can survive most extreme weather events, if appropriately sited, designed and maintained. Some weather events have short-term impacts and occur sporadically, e.g., tropical cyclones, convective storms (including hail), while others have longer-term impacts and tend to be repetitive, e.g., snow, dust storms, heatwaves, and wildfires. From an impact perspective, the damage that occurs to PV systems can be classified as acute or chronic. unavailability of climate-specific PV modules, standard products are
