How does PVsyst determine String Size?

[Vera]

Hello,

I need to recommend a string size to a client based on a JA SOLAR JAM72D42 620W module and a SMA Sunny Central 4000 inverter.
The module is not included in the database and I have been unable to obtain a PAN file.

How does PVsyst determine the string size?

Thank you,
Vera

We update the database using the requests of the manufacturers, and publish it with each new release of PVsyst.

We can't of course follow all the new products of all manufacturers in the world.  We don't want to include data without the acknowledgement of the manufacturer.

Nevertheless you can easily create your own components by yourself.

The easiest way is to choose a similar existing device in the database, modify its parameters according to the manufacturer's datasheets, and save it under a new name, therefore creating a new file in your database.

You have a tutorial for that on youtube:  https://www.youtube.com/c/PVsystTutos,   page  Component database
