Hi everyone !
I’m currently studying the potential of a PV panel into a roof, using the HB Annual Irradiance component.
What surprises me is that the hourly energy received by the panel (in W/m²) is sometimes greater than the sum of the normal and diffuse solar radiation (also in W/m²), by up to 17%.
How can the energy received by greater than the energy available?
Is there something that I am misinterpreting?
I have to precise that the panel is fixed, not following the sun path.
I’m sorry if the question has been asked before, I haven’t found it in the forum.
Thank you for your help !
Best.
