[TRNSYS-users] Type 94, maximum power



Dear TRNSYS USERS,

 

I am trying to understand the performance of Type 94 (Photovoltaic module).

I kept the default parameters, in particular: Current at maximum power point = 5.9 A, and Voltage at maximum power point = 17 V.

Then I forced the total radiation on the surface to be the reference insolation  (1000 W/m2) and the ambient temperature to be the reference temperature (298 K).

Under these conditions I expected to obtain that the module power output was 17x5.9 = 100.3 W, but I have only got 80.2 W.

Which is the reason for this difference?

How can I simulate that the module is operating at its maximum point?

 

Thanks in advance,

Regards.

 

David.
