good day, In our company we run automatic updates of software. Hence everytime there is an update of pvsyst 8 we get it automatically. Now, because it goes automatically, the question to delete older versions of pvsyst is bypassed and older versions are always removed. this is ok for pvsyst 8.x but: My question: is it possible to remove the final version of pvsyst 7.4 from this list. Because for some projects we still need open 7.4. as they are not compatible with 8.0 currently now i need to instal pvsyst 7.4 after each update of pvsyst 8! love to hear if this is possible thank u

For subsidy conditions/restrictions we have a different grid connection limitation between a fixed tilt and tracking array. currently we either: a) design these arrays in seperate projects, or b) average the grid connection limitation in a pvsyst with both types of array. would it be possible to add more options regarding grid limitations. Perhaps somewhere at the MV stations or something. thanks

Thank you! That helped me out. Ill neglect bifacial gains for EW systems for now. Age

Hi, I would like to calculate the bifacial gains of an EW solar park. I made a 3D shading scene. East west oriented. Height of 0.8m. for some reason the second orientation always uses the values height 1.5m and albedo 0.3. and i am not sure why. do i have a setting wrong? thanks in advance Age

any answers/ updates on this topic, I also would like to know Peter

Thank you André! I adjusted the low-light performance of the module and ran the simulation!

Hi all, I noticed i can adjust the Rserie value of 0.230ohm in such a way that the graph intersects my given datapoints. is this the method to adjust accordingly? Thanks in advance Age

Hello, For a batch of modules we have done some tests and concluded that although the batch passed the STC acceptance tests. The deviation at low irradiance (200W/m2) is approximate -4,7 to -5%. (-5% was the limit so the batch just passed) However this is lower than according to the panfile used in the pvsyst simulation. We calculated that for our site there is low irradiation during about 2/3rd of operating hours and therefore I would like make a simulation to calculate how big the effect of this deviation is on expected production. My question is how do I properly adjust the module characteristics to add this effect? is it sufficient to add the relative efficencies for low light performance or do I model this in a different way? Thanks in advance Age
