10-minute weather input data (52560 rows) producing output with 1314000 rows

Hi, having a bit of issue using input data with an interval of less than one hour. I am currently using a 10-minute interval "solar_resource_file" (52560 rows) as an input into my model. After running the simulation using nrel pysam, it produces an output (.Outputs.gen) with 1314000 rows. This is 25 times the size of the input file. I am wondering why this is occurring?

Thanks!

Hi Joel,

The pvsamv1 model runs a simulation over the entire analysis period so that it can account for PV module and battery degradation over time.

In your case, the analysis period must be 25 years, so you get 25 years * 8760 hours/year * 6 time steps/hour = 131,400 time steps.

Best regards,
Paul.
