balajiicon Posted February 27, 2018 Share Posted February 27, 2018 HI,There is a new parameter Ground reflection on front side shown in Loss diagram when simulated with Bifacial, this is giving a gain of 0.2% in GHI.Why this was not considered in conventional modules,please clarify.Regards,R.Balaji Link to comment Share on other sites More sharing options...
André Mermoud Posted April 17, 2018 Share Posted April 17, 2018 The “Ground reflection on front side” is a by-product of the Bi-facial model. It is not possible to calculate it with "normal" systems, without several additional parameters and a calculation model that we don't have at disposal at the moment (the bi-facial model is specific for unlimited sheds).By the way its value is very low for usual tilts. To my knowing, this quantity is never calculated (nor taken into account) by any other PV system simulation tool. Link to comment Share on other sites More sharing options...
