I want to know the answer to the following question:
Are transpired collectors more or less cost-effective than glazed collection systems?
All the background I'm provided with is that "The first commercial system was the Solar Total Energy Project (STEP) in Shenandoah, Georgia, USA where a field of 114 parabolic dishes provided 50% of the process heating, air conditioning and electrical requirements for a clothing factory.". Is that enough to answer the question?
Answer: no
