Guangzhao,<br>
I also need to know the temperature coefficient of short circuit
current and the temperature coefficient of open circuit voltage.
Both of these should be listed on the manufacturer's data sheet.
Also, is this a silicon-based panel or some other material? The
reason I ask is that silicon cells typically run at about 0.5V per
cell so 36 in series would have an open cell voltage more like 18V
than 21.5V. Its not impossible of course.<br>
Kind regards,<br>
David<br>

Could you please send me an email containing the parameters
that you are entering into the EES plugin for Type194? I have
run into some similar problems in the past and may be able to
help solve this one. It sounds from what you describe as
though the problem is in launching the plugin, not actually in
having the plugin solve so perhaps you only need to send me
the Trnsys Studio project that causes the error.<br>
Kind regards,<br>
David<br>
