Re: [TRNSYS-users] Cost Functions for Collector Types - Anyone?

Dev,

NREL's SAM uses the default of $220/m2 for flat plate. The developers of the program try to maintain reasonable default values; however, I could not find any reference in their documentation.

Best,

Matt

Subject: [TRNSYS-users] Cost Functions for Collector Types - Anyone?

Hey All,

I am doing techno-economic analysis for solar based absorption cycle and now am looking for the following types of collectors:
1. Flat plate collector
2. Fresnel collector
3. Evacuated tube collector

I found the following values in Florides et.al. (2001), can anyone comment on the accuracy as of today?
1. Flat plate :  188 $/m2
2. Evacuated tube : 307 $/m2

I seriously doubt these cost functions as they're pretty old (i,e >12years).

Any suggestions?

Thanks
Dev
