Hi,
I am trying to evaluate multiple PV arrays (Type 94) with different slope and azimuth in the same simulation model. When I couple an external data reader (Type 9) to the radiation processor (Type 16) using multiple surfaces with Type 16, I erroneously get the same output from each instance of Type 94. During troubleshooting I kept the slope and azimuth of each surface in Type 16 identical and only changed the number of modules in Type 94 (e.g. twice as many in one instance of Type 94 as the other) - still the same power output from each instance of Type 94.
When I replace Type 9/16 with a weather file reader (Type 15) the problem goes away.
