Bifacial PVsystem of rear irradiation

[juheejang2014s]

Hello, I am a user who study bifacial PV system.

I am really interested in rear side irradiation. So I want to check rear irradiation at bifacial PV system.

To check the data. I click the detail result and then hourly graph.

Then I check the Global incident on ground. but theses result are bigger than measured data.

So I want to know. What kind of index will check for rear irradiance.

If there have not any list for rear irradiance. Please check that this formula is right.

Rear irradiance = Global incident on ground * albedo

Thank you

This is not so simple.

The irradiance on the back side is the result of a complex model, which is fully explained in the Help "Project design > Bifacial Systems".

Please carefully read it.

In the results the irradiance on the back side is named "GlobBak".
