The SDK tool for Mac OSX has not been updated to reflect ssc capabilities

I've used the SDK tool in Windows and it reflects changes that went into the latest version of the ssc (e.g. the definition of subarray_x_poa_eff is the poa after IAM effects). However, I just downloaded the SDKtool for Mac and it looks unchanged from the previous version (e.g. subarray_x_poa_eff is the poa after shading and soiling). Any idea when this can be fixed?

I am happy to post this on the github page as well if that would be helpful

How can I get hourly data using "data_get_array" command in MATLAB?

Hello,

I was about to run several thousands of simulations on concentrated solar power (CSP) by using SSC in MATLAB. Although I was able to retrieve annual data from the Data Container with "data_get_number" command, I couldn't retrieve any hourly data with "data_get_array" command. Yes, I could get the hourly data from SAM, but I don't want to do that as I'm about to run a huge number of simulations and need to reprocess data with MATLAB. Is it because the names of the hourly variables in the Data Container are different from the ones in SAM?

Cell temperature model SDK

Hello,

I'm trying to estimate the annual energy output of a PV system using SAM (detailed and no finantial model) and in the modelling part I wanted to change the way the cell temperature is calculated. I believe SAM uses the NOCT model on section 10.6 of the Technical Reference, or am I wrong?

However I wanted to calculate this cell temperature using correlations I found in the literature. Since I don't have much experience in programing I'm having difficulty working this around. I've thought on two alternatives and I wanted your take on them, if possible:

SAM SDK Setup

All,
I have been trying to setup Python for building my own needs around the SAM ssc and sdk. I am following instructions that are provided here (https://github.com/NREL/SAM/wiki/Windows-Build-Instructions). I have been able to complete steps (1) through (5) and am running into issues on step (6). Additionally, one deviation I have from the instructions detailed here is the wxWidgets available is 3.1.3 and not 3.1.1 . Please provide guidance on how I can proceed .

For Linear Fresnel model, the array m_dot_loop is returned as an empty one for Python 3 wrapper

Hi,
I am trying to get the mass flow rate of saturated steam at Condenser for a Linear Fresnel CSP model from a SAM wrapper for Python 3. Since this mass flow rate is not directly defined on SAM, I am just trying to get the mass flow rate for Receiver. I am assuming that this mass flow rate will be the same as the flow rate at the condenser side as well. Please let me know if it is wrong to assume so.

Results not in the summary when exchanging with Python

Hello,
I'm wondering if there is any way to get the results that are not included in the summary table when we exchange SAM in Python. I exported the simulation model to python and it runs and just gives me the summary results. For instance, I'm looking for the demand peak with and without system which is not included in the summary table. In the SAM interface, I can find that under the monthly data, however, when using python, searching for term demand peak nothing comes up.

Creating off-grid system through SCC

Dears,
before i dig into it, I'd like to have your confirmation that I understood right: it is possible to access the SAM source code through the SSC repository files, modify it, and then rebuild the whole application with GUI and everything.
Am I correct?

My purpose is to build an off-grid CSP system, which produces electricity following an imposed load request.

Let me know, and thanks in advance

Emiliano

SDK, Python.NET or IronPython

Hello,

I would like to know if the SDK/SSC have a wrapper for Python.NET or IronPython.

Thank you

SSC

Hello,

I'm trying to add the dll file of SSC as a reference for a C# application in Visual Studio and I got an error stating " A reference to "the path of the SSC dll" could not be added. Please make sure that the file is accessible, and that it is a valid assembly or COM component"
I am kind of stuck, and I'll appreciate your help with this matter.
Thank you,
