Bifaciality not being calculated

[Emile]

Hey Team Valentine,

 

I created a new Bifacial module for my simulation with 70% Bifacial Factor. However, when I run the simulation, I get absolutely no gains or losses in the PV System Energy Balance. What could be the cause of this?

 

Your help would be much appreciated. 

 

Sincerely,

Emile

Hard to tell. Might you be so kind and send your .pvprj project file via private message here in the forum so I can have a look into it?

Thank you in advance and kind regards

Hi Frederik, 

 

My apologies for the late response. Hereby the files. Would appreciate it if you would have a look at them. 

 

Thanks in advance.

Hi Emile,

thanks for sharing the projects. I also apologize for the late reply.

My assumption is that bifacial modules are not very suitable for an east-west system, as very little irradiation reaches the back of the module.

Furthermore, I noticed that in the project that you posted, the bifaciality factor for the module is only 20% and not 70% as you wrote. Was that your intention?

I'm sorry if I misunderstood something. Please contact me again if this doesn't answer your question.

Kind regards
