Guys, your product range is incredible. Where are your modules and components manufactured?

I was able to cop an entire thermal solar system with 4 panels. 50gal indirect tank (battery) even a high end taco stainless steel pump ALL from craigslist. It's the most efficient system available. 100k BTU for 220 watts.

Do you recommend parallel piping the collectors? I have 4 collectors flat plate piped all parallel, and when the pump turns on the temp just rapidly drops I am using a 009 stainless and I think it's a little too much velocity. It's the same weather I drainback or have it filled.
