[TRNSYS-users] Solar Types 194 and 94

[Lindig Sascha]

Hello



I`m comparing Type 194 and Type 94 to see the differences between the types.

It occurred that the calculation for effref is different while the calculation the cell temperature of the type.  It seems to me that the equation for Type 94 is wrong (effref = (imr/nprl)*(vmr/nser)/(sunr)) since it does not include the area of the module?



Another thing is the calculation of it. I want to simulate small timesteps  (1s) to see how the temperature and the behavior of the system changes when changing the ambient conditions. But after the first timestep steady state conditions are already reached. Is there a way to improve that or maybe another type which is better suited for this purpose?



Thanks in advance
