I urgently need help with PVsyst! Uni dissertation submission in 5 days

[omairahm]

I genuinely need urgent help with getting this right as I have to submit my dissertation in 5 days and this the only thing that I have not done correctly but I have been trying to do it right for weeks.

No matter what I change on here that I always get something wrong in red letters.

I am trying to do a solar farm design with approximately 5254 solar panels. If someone can help me to get it right I would really appreciate it

Dear omairahm,

The message in red is normal because your inverter has a very high power compared to the Total STC power of your PV array.

You have a 1665 Kwp PV array, so you must choose an inverter between 1200 and 1500 KWac

If I change one thing I get another wrong, now I got this:

Dear,

The message in red indicates an error.

You must therefore make changes in order to match the characteristics of your inverter.

Check your PAN file. Your Vmp value does not seem correct, it is too high. For a 1500V system, you should be in the mid to high 20's for string length. You also want a higher DC/AC ratio, 1.2 to 1.3 good range. I suggest getting a new PAN file, or double checking the IV characteristics against the datasheet.
