Evaluation of Anti-Glare coating glass for photovoltaic modules

AGC(Anti-Glare coating) glass which has the property to reduce the glare on the PV(Photovoltaic) module by the reflection of sunlight on the PV module was evaluated. In spite of the similar properties of the transmittance with AGC and ARC(Anti-Reflective coating) glass, the reflectance of AGC glass was higher than ARC glass due to diffuse reflection. It was observed by measuring gloss and haze. Moreover, the same effect was observed on the manufactured PV module samples. The glare reduction by reflection of sunlight on the PV module in outdoor exposure was visually observed for AGC module and the luminance value of the AGC module was decreased about 90% compared to the ARC module. The AGC module was observed diffuse reflection, but the output power was similar to the ARC module.
