Description

SAM Feedback_Round Table.zip

We recently revised labels of time series irradiance outputs for the pvsamv to make the progression from available irradiance to irradiance incident on the PV cell easier to follow: https://github.com/NREL/ssc/pull/1153

This request is for some additional improvements:

  • Monthly "POA front-side irradiance total" should be "POA front-side irradiance total after reflection and soiling (IAM)" to be consistent with time series output labels.

  • "(IAM)" in the labels is a little abiguous. Something like "IAM losses" would be clearer.

  • For mono-facial modules, "POA front-side total..." and "POA irradiance total..." are the same and appear to be duplicate variables. Consider only reporting "front" and "rear" outputs when bifacial option is enabled.

  • Consider adding calculated "Module efficiency" to loss diagram:

Research direction

Start by reviewing the pvsamv monthly and time-series output labels and the loss diagram described in the issue, using the attached feedback slides for the intended wording. Done means the labels distinguish IAM losses clearly, duplicate mono-facial outputs are handled when appropriate, and the module-efficiency request has a decided outcome.
