I use SAM on a computer with limited internet access. How can I avoid using up the 15 starts SAM allows without being connected to the internet? You can avoid using up your 15 starts by not closing SAM and hibernating your computer instead of turning it...

Paul, there seems to be a problem with the Mac OS X (Yosemite) version of the report as well. When you run it, you get an error message that it cannot be opened even though the report does in fact save it to your hard drive and/or cloud storage service....

Hi Mike, The module and inverter inputs that do not appear in the inputs browser are inputs that are stored in a library. For example, the module "Material" input shown on the Module input page for the CEC Performance Model with Module Database is...

Dear Arsh, Thank you for attaching the file. If the shading scene were for a single building with four sides, or if all three buildings in your scene had the same orientation, I would have suggested that you set up each subarray in SAM (on the System...

Dear Farhan, First, please make sure that you are using the same version of SSC in your API calls that SAM is using. To see the SSC version number for SAM, open the Help browser and click About. It is possible that the inputs in SAM are not identical to...

SAM assumes that all modules in the PV array are connected either to a single inverter or to a bank of identical inverters with a single input. For that reason, all subarrays must have the same number of modules per string to maintain a single voltage...

Dear Saeid, One approach to modeling your system would be to create a separate case for each reciever/field, and then use the combine cases macro to combine the cases into a single project. To find the combine cases macro, click the Macros button at the...

I wondered if it was possible to review simulated output from multiple subsystems in one view. I have a system with two models of inverter and created a file with two sub systems, one sub system for each inverter type. I would like to view the...

Hello, When you use LK to interact with Excel using Excel Automation, remember that SAM works with a copy of the Excel file in machine memory. It does not save the Excel file with your data, so it does not modify the Excel file. You can test this as...

Hello, There are a couple of problems with the data in your weather file. * There are several hours with GHI values above 2,000 W/m2. * The weather file is missing wind speed and ambient temperature data. Please see the "Weather Data Elements" topic in...

I've added a model, I am open to change the module and inverter or any other configuration. Being honest I'm so new to SAM and trying to just forecast a solar load shape for industrial, commercial and residential sectors. Then later I will run...

Hi Susan, I'll have to go through and verify the example you've given, the algorithm is rather complicated. It's based on this paper: www.sciencedirect.com/science/article/pii/0142112382900184 I'll try and go through in the next day or two and run your...

Dear Kevin, You can use the "Download Electric Load" macro in SAM to access the data: * Start SAM, and open or create a project with the Detailed Photovoltaic or PVWatts performance model and Residential financial model. * Click Macros at the bottom...

For now, SAM can only model a system with a single type of inverter, and only inverters with a single MPPT input. You could use the Combine Systems to combine results from two different cases in your SAM file: One case would be for the portion of the...

Hello, I answered your other post on the main SAM support forum: sam.nrel.gov/node/75222 There are a few differences in the functions that are available from the script editor in SDKtool than its counterparts in the SAM user interface, but you can use...
