SAM: New Version, New Site

February 1, 2012

The Solar Advisor Model (SAM) makes performance predictions and cost of energy estimates for grid-connected power projects based on installation and operating costs and system design parameters that you specify as inputs to the model. NREL recently released SAM 2011.12.2 for Windows and Mac OS with several new technologies and capabilities, including linear Fresnel CSP, P50/P90 weather variance analysis, and biopower modeling, as well as general improvements, such as PV case study sample files and integrated hourly data plotting. The new SAM version is available for immediate download at its new dedicated site,, along with training materials and a schedule of presentations and webinars.
