Parabolic Trough Collector

I am trying to model the performance of parabolic trough collector for
residential application with capacity of only 50 kw.
I can not configure the commercial PTC in SAM examples.
An example for residential building with small capacity will be appreciated.

Hello,

SAM's CSP models are designed for power generation systems where the solar collector delivers thermal energy to a steam turbine that generates electricity. The models are not well-suited to modeling systems with small rooftop collectors that help meet a building's thermal load.

Best regards,
Paul.
