PV Module
Current Coefficient [mA/k]
This value shows by how many amps the current increases when the module temperature
rises. The higher the module temperature, the higher the current, ie this coefficient is
positive.
Power Output Coefficient [%]
The hotter the module, the lower the power output. This coefficient is negative and is
proportional to the nominal output.
Incident Angle Modifier [%]
The incident angle modifier is a characteristic of the material covering the module (glass).
The glass reflects part of the radiation away from the module resulting in a loss of current.
The incident angle modifier reduces the amount of direct radiation falling onto the module.
The correction factor for diffuse radiation lost through reflection is assumed at 95%.
Maximum Module System Voltage[V]
Each electrical appliance has a maximum voltage limit. This value refers to the maximum
voltage that a array can support in order to ensure that no damage is caused to the
modules. If the maximum voltage is too high, you should reduce the number of modules in
series.
Specifications for the Dynamic Temperature Model:
Heat Capacity [J/(kg*K)], Absorption Coefficient [%], Emissions Coefficient [%], Weight
[kg]
These are the parameters for the dynamic temperature model required for working out the
thermal balance equation.
