1. • Atmospheric limitations
• How to quantify the effects of clouds on
the yield of a PV module?
• Modelling the atmosphere and PV power output
• Cloud inputs from APOLLO and inputs from
the libRadtran library
• Spectral dependency by the use of the QE
of the PV module
• Two-diode-model for c-Si
• Comparison of simulation with local measurements
• Different days with different dominant cloud
types
• Good consensus for clear sky, other conditions
show good results only with smaller simulation
