Hello Paul!
I am using SAM to see the thermal energy output of a parabolic trough field with thermal storage system.
I have read your answers to similar questions in the forum. I noticed that in most cases, there was only a PTC field with no storage.
What I understand from your responses is: For a PTC solar collector field without storage, if I choose a big power block compared to my solar field, the effect of power block start-up/ shutdown and solar field defocusing would be negligible. Therefore I can use the value of solar thermal output as thermal energy from the solar field.
- What about my system that has a thermal storage, does above apply? If not could you give me some advice please?
- Another question is about freeze protection. Does this temperature have any relation with climate? For my case which is in Australia, should I consider Lower temperature or 150 C is a typical value applicable for all different locations?
Thank you for your kind help!
