POA from pyranomiter with zero DC power output was created by Beneduce

Dear Team,

I am trying to perform a "Detailed PV Model - No Financial Model" simulation on a single PV module.

I have a limited input POA irradiance dataset (about 3 months, from Septemper to November).

I am wondering why if I set "POA from pyranomiter" the array DC power output modelled is always zero (see meteo file, module data and project in attachment). There is no self-shading.

If I run the simulation setting "POA from reference cell", it works and non-zero DC power production is obtained, instead.

Hi Simone,

The weather file you attached has each line enclosed in double-quotes (") that is causing SAM to misread the data in the file. Please try removing the quotes and let me know if you still have trouble.

Best regards,
Paul.
