In PVsyst 6 HELP, in the point about AGEING http://files.pvsyst.com/help/index.html there is this note: "NB: The simulation for a given year takes the average loss calculated mid year. For example for the 10th year of operation, the ageing loss factor will be calculated over 9.5 years. For the usual simulations of PVsyst (first year) we should indeed consider the degradation after 6 months (0.2% in our example). This is usually neglected" And I would like to know why for the first year operation it is used the degradation after 6 months and is not used the degradation for the whole year. Thank you.
