Error from parametric simulations with large number of runs

Hi Henrique,

I tested the parametric simulations and did not encounter the error. I used fewer weather files than the 411 in your file. You might try one of the following:

1. Break the parametric simulations into smaller groups of files, maybe up to 100 at a time.

2. Use LK script to run the simulations. This gives you more flexibility because you can set values of inputs, read outputs, and write data to files. There are a couple of sample scripts on GitHub at NREL/SAM/tree/develop/samples/LK Scripts for SAM that you can try (see the download instructions at the bottom of the page: Download the solar-resource-simulate-multiple-files.lk and hourly-data-from-multiple-weather-files.lk files, and then in SAM click File, Open script to see and run the scripts.

Best regards,
Paul

Hi Henrique,

As of SAM 2020.2.29, SAM's photovoltaic models run in "lifetime" mode, which means that they run a simulation for each time step over the entire analysis period instead of a single year, so the simulations involve many more calculations in SAM 2020.2.29 than for the same system in SAM 2018.11.11.

We designed the parametric simulation feature to run a few simulations for quick parametric or optimization runs. For larger sets of runs, I would recommend using LK script: sam.nrel.gov/lk-script.html

Best regards,
Paul.
