(well, for openLCA, you should use the ecoinvent version from Nexus, as written in quite some posts here)

thank you - I would recommend to use the latest version, 3.7.1, and then either unit or system process ("LCI"), for one ecoinvent "system model" (APOS, cut-off, consequential). The "regionalised" versions contain more regional flows compared to the original ecoinvent database, this is a change done by us so that these databases then better reflect impact methods where the impact depends on the location.

Andreas Ciroth...From literature, I came to know that for processes like LCA of Photovoltaic production, Recycling processes etc cut off LCI modelling approach is suggested.
 Should I download all modelling approaches or just cut off ?? and cut off unit or cut off system would be required for PV production, recycling LCA processes.
