There are more than 20 pages that cover the $1K solar water heating system, its components, component testing, performance testing, and the cost and payback analysis. So, you really need a roadmap to find everything -- here it is.
I'm very open to answering
questions on the system, but please check to make sure your question is
not already covered on one of these pages.

A detailed overview of the $1K Solar Water Heating System...
Developments (or the lack of) in low cost solar water heaters...
The Copper/Aluminum Version...
Prototype performance testing...
Galvanic corrosion...Optimizing the thermal conductivity of the fin to riser joint....
Small diameter headers...
Copper/aluminum collector flow distribution test...Prototype performance testing...
Serpentine drain back test...
Stagnation temperature test...The collector in the prototype system... (this is my actual system -- its the PEX/Aluminum version)
Month by Month performance... (performance of my system for a full year)
Collector performance... (how do these homemade collectors compare to commercial collectors?)Very cold day performance... (PEX collector performance on a -20F day)
Thermal performance of the plastic pipe coil heat exchanger
Prototype PEX collector.....
Stagnation tests of PEX collector.....
Drain back testing of serpentine collector.....
Copper/aluminum collector flow distribution test....
Optimizing the thermal conductivity of the fin to riser joint....
Example $1K System Documented by Their Builders... -- Thank You!
