Aging Effect & Bifaciality feature in Dome

[saddam]

Dear Andre,

I hope all is well,

I have a ground mount project and i would like to clarify the following points:

A- Fixed Mount Variant:
I made three variants (20Y Aging, 5 Day Unavailability), (1Y Aging, 5 Day Unavailability), (without Aging & Unavailability)
1- how the following value calculated (the global irradiance on rear side 201 W/m2), and from where this percentage come 8.4%.
2- You can see from the comparison (attached) when i consider the aging for 20Y & 5 days Unavailability (nothing else has been changed), some factors had been affected and all of them is understood, except the global irradiance on rear side it increase from 198 w/m2 to 201 w/m2.
3- My company is a developer Co., and they use financial model to evaluate the IRR, in this model they insert the aging as a fixed value 0.3 yearly, and it applied on the specific yield for 25years, my question is : I told them that by this way we are not considering the effect of 25Y aging on the other parameters as it clear showing in the loss diagram of PVSYST , almost 9 parameters has been effected by the aging, please if i wrong correct me.

B- Dome Variant:
As we know in the dome option the PVSYST will not allow to activate the Bifaciality function, so in the near shading i convert the domes to fixed table, I would like to confirm whether this solution was correct.

Lastly, what is the way to send you the zip file of the project, just to have a look on the above solution that i made it to activate the Bifaciality feature in dome option?

Your guidance on these above questions would be greatly appreciated.
