In some special installation sites, such as airports and large urban building sites, the control of the surface reflection brightness of the photovoltaic module is very strict, and the solar module used is required to achieve a sufficient anti-glare effect. For example, some european customers currently require a householdUnder the irradiation of 100000lux of external sunlight, the maximum reflection brightness value measured in the observation range of observation angle 0-60 deg must be less than or equal to 30000cd/m2。
