I am trying to define Hitec salt in a power tower system and I'm getting negative values for energy. I define it using the ecuations giving in next document:

Dear Carlos,

That link is to a very old draft description of SAM's empirical trough model. Please see the Help system in the current version of SAM (also available as a PDF on the Download page at sam.nrel.gov/download ) for instructions.

Also, the following post on the SAM Support forum may be helpful:

Best regards,
