Dear Dr. Falah,
SAM is a good place to start for modeling parabolic trough, power tower, linear Fresnel, and dish-Stirling CSP systems. I would suggest that you or your staff
download
and install the software. The CSP models require some knowledge of system designs and familiarity with project costs and financial arrangements. You can use the software's Help system, and information in this forum and the
Learning page
to learn more about SAM.
Best regards,
Paul.
