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...

Hi Jabbour, When you use the Combine Cases macro, SAM simply adds the output of two separate systems together and uses that "combined" output as the generation profile for the financial cash flow model. It is not possible to model a CSP system that...

Hi Vedika, In general, SAM is not an optimization model. It runs a performance model simulation to calculate the electrical output of a power system and a financial model simulation to calculate the cash flow of an energy project. There are some...

Hi Brock, Thank you for attaching your wind resource file. This is a bug that we will have to fix. I'm not sure yet of the cause. In the meantime, as a workaround solution, you can manually "combine" the generation profiles of the two cases: 1. Run a...

Hi Gabriel, When you compare results between SDKtool and SAM, make sure that SDKtook is using the same ssc.dll file as SAM. You can check the path in the bar at the bottom of the SDKtook for the path to ssc.dll, and the SSC version number should be the...
