juheejang2014s Posted July 3, 2019 Share Posted July 3, 2019 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 Link to comment Share on other sites More sharing options...
André Mermoud Posted August 2, 2019 Share Posted August 2, 2019 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".
