Anti-Glare Effect of Deeply Textured Cover Glasses for Solar Modules for Installations Close to Airports and Heliports

28th European Photovoltaic Solar Energy Conference and Exhibition; 3069-3072
In this work we show that deeply textured glass covers can solve an important issue which is the risk of glare due to sunlight reflection on PV modules. We introduce a quantitative measure of glare as the luminance value in the brightest direction and we observe that SGGAlbarino P glass covers allow a reduction of more than 2 orders of magnitude compared to reference smoothly textured cover glasses, from more than one million cd/m² to less than ten thousand cd/m². The physical explanation of this extremely efficient anti-glare property of SGGAlbarino P is to be found in its surface topography which shows both a very broad slope distribution and a randomized aspect.
