Dear admins,

I have a question regarding performances of the system that I have created. 

I manually set in the program which inverters will be used, the string lengths, and their connections to the MPP inputs. The system is functioning, and there are no errors, but I don’t know how to assess whether the system’s performance is satisfactory. If there are any parts with significant losses, or any problematic spots, considering that I configured everything manually, please tell me. Also, if you could point out the fields I should check when manually setting the inverter selection and string connections, I would appreciate it.

Thank you in advance,
Gordana

I worry about this STC Conversion -77,95%, but I don*t know if it is related with cable plan, because I didn*t configure cables.

Thank you in advance,

Dear Gordana,

Thank you for your inquiry.

Your PV System Energy Balance looks fine. In our view, there are no particular anomalies, not even in the STC conversion. A module efficiency of 22 per cent is plausible.

We recommend that you take a look at our example projects:

Alternatively, you can create several project files with different modules and different inverter configurations and use the project comparison to compare the simulation results with each other:
