Solar Load

Hi currently i am doing a simualation of the solar pv cooling effect, however i encounter problem which is how do i want to apply the solar radiation towards the solar PV( indicated in the red region)
so that when i simualate the temperature of solar pv will increase with time due to the exposure of solar radiation
link to my project tq

Hi there, you could for example apply a wall condition with temperature type of External wall heat flux, then enter the heat flux value as the heating power of the sun divided by the area of the surface. Please check this page for the usage of this boundary condition:

thank you very much sir for the clarification
