Different results between Simulation and batch simulation

[nicolasrata]

Hi,

I'm planning to do a batch simulation to test a setup in different cities.

Before that I did a test with a batch of only 2 variants to check the results against a manual simulation for each of the variant.

The 2 variants :

• Same plane, same orientation, same modules, same parameters
• One variant with a 100KTL
• One variant with a 50+40KTL

100KTL

50+40KTL

 

The losses in the batch params are the same as the ones in the detailed loss.

 

Do you have an idea about the following things :

• Why is there a difference between the module quality for the 100KTL variant ?
• Do batch simulation work with multiple inverters ?
• Is it normal to have variation between batch simulation and manual simulation ?

Thank you

Ok, after doing some trial and error I can answer to myself.

• Difference between module quality values.
  • The default value in detailled loss is shown at -0.7 but might be round at -0.8 in the results. Need to change it manually to-0.7.
• Do batch simulation work with multiple inverters ?
  • Yes but you cant make change on the chain or inverter in the params file because it will apply to all the inverters.
• Is it normal to have variation between batch simulation and manual simulation ?
  • If the parameters are correct there is no variation.
