Solar PV in the airport environment: A review of glare

The reflectivity of the PV module is the amount of incident sunlight that is not absorbed by it. It is also the reverse of absorbed solar radiation fall on the PV array. In this regard, the PV panel manufacturer typically submit a letter stating their PV panels will not reflect light with a luminance higher than 20,000 cd/m 2 (Service
