[TRNSYS-users] TYPE 194 INPUT

[Lindig Sascha]

Hey David

Thanks for taking care.
Module_01 is SOLBIAN Plexiglass CV70,
Module_02 is PowerSmart PV-glass from Onyx (636BN-12451242_00)
and module_03 is the Saint Gobain SGS PowerSmart 125.
I hope that's helpful I don't have model numbers.

Thanks in advance

Sascha

Sascha,
  Could you please send me the manufacturer and model number of each of the panels? I may have their parameters in a data base. The Type194 plugin is giving me some problems as well.  As a side note, I think that you could easily model the first panel (the monocrystalline silicon panel) using Type94 with good results. The other two are best modeled using Type194; hopefully we can get the parameters that you need.
Best,
 David

Hello

I have a problem. I`m unfortunately not able to use the Plugin for Type 194 to figure out the the recommended values R_sh_ref, R_s_ref, a_ref, I_L_ref and I_0_ref. I tried to calculate it by myself with the 194 plugin but its not working at all.
I wanted to ask if someone can help me to provide me with the parameter of these 3 modules. Here are the needed values:

Module_01:
Area: 0,585m²
Material: mono-Si
Cells in serie: 18
Vmpp: 9,5V
Impp: 7,6A
V0C: 11,3V
ISC: 8,1A
T_coeff of ISC: 0.05 %/K
T_coeff of V0C: -0.33 %/K

Module_02:
Area: 1,563m²
Material: a-Si
Cells in serie: not sure
Vmpp: 70,5V
Impp: 1,35A
V0C: 94V
ISC: 1,5A
T_coeff of ISC: 0.09 %/K
T_coeff of V0C: -0.28 %/K

Module_03:
Area: 1,05m²
Material: CIS
Cells in serie: 104
Vmpp: 43,7V
Impp: 2,86A
V0C: 58,8V
ISC: 3,27A
T_coeff of ISC: 0.1 mA/K
T_coeff of V0C: -140 mV/K

Thanks a lot. It would be great

Best regards

Sascha
