Hi Andrew

I am trying to simulate Bi-facial modues , but having few query regarding the same

1) Is it necessary to select the unlimited shed in the Field type in the orientation tab for simulation of Bi-facial modules ?

2) can we simulate the bi-facial module with fixed orientation or several orientation if we design 3D for the same ?

Please refer the attached image for the same.


Thanks
Nitin Panwar

Hello Nitin,

I do not believe bifacial simulation for use with 3D scenes is yet available, and must use unlimited sheds at the moment. 1) Yes. 2) No

See: viewtopic.php?f=24&t=3544&p=8825&hilit=bifacial#p8825

Thanks Solar Guru for your reply.

I have another query regarding the below mentioned points.

Structure shading factor (default value is 5%) -

1) On what parameters basis the shading factor is taken as 5 % only ?



Mismatch loss factor (default value is 10%)


1) What does mismatch at back side of modules means and why this value is taken 10 % as default ?

Thanks

This value has been updated to a default if 5% (as of v 6.7.4 I think), as it was believed to have been overestimated @ 10%.

I dont have any info on the shading loss factor, so can't help you there.

It is sometimes useful to read the Help ...

See "Project design > Bifacial Systems > Bifacial systems procedure"
