Jeff,<br>
Type30 is for collector array shading if you have two rows of
collectors, both sloped at the same angle but one behind the other. I
think what you want to do instead since your collectors are facing
different directions is to define two surfaces in Type15 (the weather
processor) or in Type16 if you are reading your own data file and
processing it. Then define two Type94s, one for each of the two arrays
that face different directions.<br>
Kind regards,<br>

type="cite">I'm trying to model a PV system that is really two
separate arrays intertwined. I need one array to face East, with an
individual panel angle of 15 degrees and the entire array slope of 10
degrees. The second array needs to face West with the same angles. This
is supposed to be somewhat like tracking on a North South axis, only
with two fixed panels, one in each direction. <br>
<br>
I've been attempting to do this by using Type 30a. Also, when inporting
the weather data the azimuth and slope of the surfaces can be set. Does
this interfere with setting the slope and azimuth set in type 30a?<br>

Thank you,<br clear="all">
