世界太阳能市场继续扩大。然而，为了与传统能源竞争，光伏（PV）模块必须能够持续可靠地高性能。由于模块上的盖板玻璃被污染，会发生性能损失。可通过使用疏水涂层来减少污染。这些降低了表面能，从而最大限度地减少了对污垢的粘附。这些涂层有助于减少维护并保持一致的电力输出。目前尚不清楚如何评估和比较疏水涂层。在本文中，测试方法来模拟涂层的经验，在其寿命的应力进行评估。这些测试方法有助于预测涂层在应用于太阳能盖板玻璃时的耐久性和使用寿命。来自不同标准的各种测试方法已应用于疏水涂层玻璃表面，并进行了优化，以模拟真实的户外条件。设计了砂击试验和水滴模拟试验，研究了砂和雨对防水性能和耐久性的影响。
The world market for solar energy continues to expand. However, to be competitive with traditional energy sources, photovoltaic (PV) modules must be capable of continuous and reliable high performance. Performance losses occur due to the soiling of the cover glass on modules. Soiling can be reduced by using hydrophobic coatings. These decrease surface energy and thus minimize adhesion to soiling. These coatings can help reduce maintenance and retain consistent electrical output. It is not yet clear, how hydrophobic coatings can be assessed and compared. In this paper, test methods to simulate the stresses that coatings experience in their life-time are assessed. These test methods help to predict the durability and useful lifetime of the coatings when applied to solar cover glass. Various test methods from different standards have been applied to hydrophobic coated glass surfaces and optimized to simulate real-outdoor conditions. A sand impact test and a water drop simulation test have been devised to study the effect of sand and rain on hydrophobic performance and durability.
