<DIV><FONT face=Arial size=2>Dear Trnsys´users,</FONT></DIV>
<DIV><FONT face=Arial size=2> When working with radiation processor type
16a in "tilted surface mode 4", which corresponds to Perez model for the
calculation of diffuse radiation, I get very high values for diffuse
radiation.They are as high as 2400 W/m2 ,which makes my
simulation of a PV array doesn´t work .</FONT></DIV>
<DIV><FONT face=Arial size=2>I have tried the same simulation with mode 1"
isotropic model" and everything is ok whereas with model 2 and 3 the same
problem appears with diffuse radiation values.</FONT></DIV>
<DIV><FONT face=Arial size=2>Does it mean that "tilted surface model 2,3 and 4"
can´t be used for all radiation horizontal values? Or perhaps am I doing
something wrong?</FONT></DIV>
<DIV><FONT face=Arial size=2>Thanks a lot.</FONT></DIV>
<DIV><FONT face=Arial size=2>Kind regards,</FONT></DIV>
