Dear All, I got some strange results with type 551b and investigated a little bit... I pronted the output of SolAltAz_d (solar altitude angle in the plane of the field azimuth) for a Boston tmy2 file with 37deg slope and the result is this: see picture Can someone please have a look and give a comment if this looks normal? During summer month the angle only varies from around 70 to 95 degree... as the sun rises, it should start from somewhere close to 0 right? Thanks in advance and have a nice weekend!!
