Questions about Parabolic Trough Collectors

Greetings, 
 
I am designing a Solar Industrial Process Heat system using Parabolic Trough Collectors. The system includes a solar collector field and one heat exchanger to transfer the thermal heat to my process. I have some general questions: 
1) The installation cost of the collectors is shown in this report at $170/m2. Is this only for SkyTrough? because I am using the Eurotrough ET150. Also, is this price valid until 2023, or is there an update? 
2) In the PTC field, should there be a pump to pump the fluid through the tube? If yes, does the installation cost above include this pump? 
3) How much should the site improvement cost be? Is it always $30/m2?

Best,
AB,

 

Hi AB,

SAM's default costs are just a starting point for your analysis. You should do your own research to determine what cost inputs are appropriate for your work. SAM does not automatically change the costs when you change components. For information about the default costs for CSP models in SAM, see sam.nrel.gov/concentrating-solar-power/csp-cost-data.html .

You should include the cost for all necessary equipment for your design. The default costs are appropriate for the default system design, but if you change the design, you'll also need to change the costs as needed.

The site improvement cost depends on the terrain, and equipment and labor costs for preparing the terrain for the installation.

Best regards,
Paul.
