What is the relationship between PV-power and the transparency of a glass-glass PV-module?
The nominal power that can be obtained in a glass-glass PV module is dependant upon the level of transparency i.e. the distance between PV cells in the module. The following table shows the relationship between transparency and approximate PV-power. The g-value is indicated is an important parameter for designers to calculate the solar energy gain to the interior of the building and this also shows the level of solar reflection provided by the PV-module.
