The SAM web site will be upgrading Monday, May 23 from 4:00-5:00pm (Denver/mountain time). 

After doing a major change to our infrastructure, we have found a minor issue that we have corrected but will need to reboot the web site for it to take affect.

To make it as convenient as possible, we have scheduled it for Monday, May 23rd at 4:00pm (mountain). The process takes 15-20 minutes, but the site will only be unavailable for a short time. However, your session information will be lost (eg if you're writing a post, what you have written could be lost). 

NREL Parabolic Trough and Power Tower Studies SAM 2013.1.15

The following files are for analyses comparing SAM results for the physical trough model and molten salt power tower model to data from real systems in Spain. These analyses were performed using SAM 2013.1.15. If you would like to run one of the .zsam files to compare results with those shown in the documents, please be sure to download and install the same version of SAM as the one used for these case studies.

Published Paper on Power Tower Study SAM 2017.9.5

The following research study on short-term forecasts of DNI for plant operation is based on SAM simulations of a plant similar to the Gemasolar power tower. The paper discusses the SAM input parameters, and the authors have provided the SAM 2017.9.5 file below to accompany the article:
