Hi PVsyst support team, While running different scenarios (different DC/AC ratio) for the same inverter, I noticed that the hourly night consumption for each run is a different, ranging from 2.335 for one simulation down to 1.9945 for another simulation. My understanding is that the night losses are mainly related to the transformer iron losses. but my inverter quantity and all the losses I maintained constant.

Similarly, i am seeing similar issue. I tried to run the simulation once with and without power factor. which gave a difference in output power. However, i am not seeing added clipping losses. Where is the extra loss coming from? and how to justify just loss?

I have been trying different layouts, where my string count and DC, LV, MV and HV losses are changing. I do not see the option to add MV and HV cablers as variables. is there a way to include them?

I am running ageing simulation, i need to produce hourly files, for a few of the simulation years, but they are not produced. is that possible? i ticked the generate report and output file tabs, and i get a pdf report, but no hourly file.

Hello, regarding the temperature shift, what bases should i consider for this, does it depend on inverter installation method (ex. directly in field, under canopy, in Skid, etc.), do I get this value from the manufacturers, and does PVsyst have any recommendations for values or methodology to consider?

I have a project where I was asked to add a geo membrane to improve Albedo. The supplier gave me the Albedo value for the membrane but also gave me the annual degradation values for the material reflectivity. I wanted to run a batch simulation where i change the Albedo with the years but i can't find this option. Is there another way to do it?
