I want to know the answer to the following question:
What was the first commercial solar concentrating system?
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: yes
