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). 

CSP Overview

Mechanical engineering course lecture providing an overview of CSP Overview of CSP technologies.

CSP Troughs and Power Towers

Modeling Molten Salt Power Tower Systems in SAM 2017.1.17

Mike Wagner describes the molten salt power tower model in SAM 2017.1.17, with a discussion of choosing a reference DNI value for a given location, optimizing the solar field using SolarPILOT in SAM, and using the automatic dispatch optimization option.

Modeling Power Towers in SAM, Feb 2015

This webinar provides an overview of SAM's power tower models. Mike Wagner of NREL presented this overview on February 19, 2015 with demonstrations in SAM 2015.1.30 showing how to use SolarPILOT to automatically layout and optimize the solar field.

Modeling Parabolic Trough Systems, Jun 2014

The Modeling Parabolic Trough Systems webinar was presented on June 18, 2014 by Michael Wagner of NREL. It describes how to model a parabolic trough system with molten salt heat transfer fluid using SAM's physical trough model.

Presentation slides (PDF 4.29 MB)

The following SAM file (.zsam) was used for the demonstration (use SAM 2014.1.14 to open the file):

  • Parabolic Trough System with Molten Salt HTF (ZSAM 104 KB)

The following SAM file (.sam) is a similar example, but for use with SAM 2015.1.30 or later:

  • Parabolic Trough System with Molten Salt HTF (SAM 97 KB)

Industrial Process Heat

Overview of New Industrial Process Heat and CSP Capabilities in SAM 2017.1.17

Paul Gilman and Ty Neises describe the new parabolic trough and linear direct steam models for solar industrial process heat (SIPH, or IPH) applications, and also briefly describe an update to the CSP generic model.
