Also, when using PVC files or you have any shade scene where individual tracker rows are being modeled, you will need to use the backtracking management option and select a representative pair.

Shading will be accounted for, and will reflect the different heights and tilts for calculating shading. In terms of tilt, the POA irradiance will be adjusted depending on the average tilt of the shade scene. This is done automatically by the software.

Use total module length. This is standard practice

Same OND files? Is one using MPPT share and the other not? Post screenshots from System menu showing the arrays for each.

Ohmic loss inputs in PVsyst are up to the user to define, so you should be considering the current under bifacial conditions when sizing your cabling and determining voltage drops, etc. PVsyst will consider the hourly I^2 x R losses inclusive of bifacial gain, but this is not determining what the initial input is, that is determined by the user based on their design.

This approach is necessary, far shading doesnt take into account the electrical losses, only irradiance loss, and not down in the plant level. It is a global loss applied to the entire site, whereas with topography in the shading scene, you might have shading only on certain portions of the plant. If you have complex topography, it would be advised to understand the shading losses in some way or another, whether you account for that inside PVsyst or outside. If you have table penetrations, you have two options. You can increase the table spacing under the zone settings, the default value is 0.2m. Or under tools, disable field interpenetration check. That is quite the terrain you have there. Is this an actual site, or just a test?

Check if that is the case with fixed tilt tables. This feature was made well before we were able to model tracker tables independently and place onto terrain.

Your screenshot is showing for a high voltage input (P in_DC, P Out_AC) in W

That could be too high, degradation of albedo will mostly occur in the first 2 months to 1 year, and level off after that. It will depend on your roof, materials, location, weather conditions (i.e. rainfall), whether the white roof is new or pre-existing, etc. Look for studies on the subject.

To do both simultaneously, 1) modify the OND file to the inverter limit, 2) set grid limit to limit at a second value at the injection point, account as a separate loss. You can also do all of this post-PVsyst without modifying the OND file, but you will need to account for the AC losses separately as well.

Set to both nominal and max. Generally a limitation at the injection point supersedes, or is more common, than a limitation at the inverter. Setting an inverter limit means the inverters are being curtailed, and are being modified by the inverter manufacturer with an adjusted nameplate (they will be providing a letter to certify the new nameplate, etc.). It all depends on your project requirements, what type of installation, grid requirements, etc.

This should be under 'How-to' or 'Simulations'

Check your OND file. If on the Output Parameters tab, Nominal AC Power definition is set to Apparent power, you will need to select in Energy management > Power factor "inverter PNom defined as Apparent Power", and if applying a grid limit, on that tab, under specified power factor, select limit in active power

Unlimited sheds are facing south, unlimited tracker at -22 are facing east.

add dummy mppt to OND file, share the inputs in one of the inverters between two arrays with two different panel types. you will not have one module type per inverter.

Maybe this can help

The collector area is not the same in both simulations. Can you retest with identical systems?

One additional request for the carbon emissions report, the units for energy don't change with the report options setting for units, would be great to have it change there also.

It would be great if in the carbon balance menu (or the entire Economic Evaluation tool), EGrid wasn't fixed to the project and instead could be entered by the user. We don't always have complete losses in PVsyst and often post-process for additional losses and considerations, but could still make use of the economic evaluation and/or carbon balance tool if we could enter Egrid.

Search "Batch mode - Parametric studies" in the help menu.

Module temperature can be calculated, there are formulas online you can search. In PVsyst, there is an output variable called Tarray, in some places of the help it says cell temperature, and others, it says module temperature. It would be great to get some clarification here @Michele Oliosi.

Yes, there is a section where the trackers are listed, then below, the objects, then in a new section where zones and groups appear. Create a group then add trackers to it. Select the trackers then I think you right click the group and add to it.

For why PVsyst shows 80 modules instead of 81, check the module spacing you have in whatever software is generating the PVC file, and what you have by default in PVsyst. If for example you are using PVCase with a module spacing of .01m and your PVsyst default is .02m, you will not get the same number of modules. This does not really matter though. PVsyst is calculating shading losses here, nothing else, so if the area of the tracker block in total is representative, then I dont think it matters if it says 80 or 81. The generation calculations are done based on the system definition, not by the module quantity in the shading scene. Try setting PVsyst default module spacing to 0.00 (X and Y), then reimport the PVC file.

Set the partition and select all tables of the scene, and all tables will adjust even if you have 1, 2 or 3 string trackers. It will be defined based on the dimensions of the partition.

Near shadings consists of beam, diffuse, circumsolar, and albedo losses. @PVsyst, circumsolar is missing from the help menu, see attached.
