Anti-glare glass solar

Tempered glass, as the protection cover of PV modules, will partially reflect some of the incident sunlight by Fresnel reflections and create glare, especially at larger angles of incidence, which is harmful to energy efficiency and effective operation of PV modules in special places, such as road driving of automobiles and aircraft navigation. 1–3 To reduce the reflected sunlight and glare intensity, one of the solutions is to use anti-reflection coating and anti-glare coating on the cover glass. 4–6 However, the coating will fail as it becomes thinner or damages over time in outdoors. 7 In other methods, surface texturing is used to redirect more incident energy into the glass and spread out the reflected beam. 8–11 The most commonly found structured surfaces on the glass cover of PV modules for anti-reflection include inverted pyramids (IPs), 2D grooves, and bump structures with size range from 0.2 to 2 mm. 12–15 The improvement from the structured glasses varies from 2% to 8% due to different field conditions, such as climate, inclination angle, dust condition, and cleaning method.
