I have compared the heating performance of two interesting home built DIY (Do It Yourself) solar collectors: a traditional flat plate collector and a concentrating parabolic trough collector. The tests involved mounting both at the same time in a solar test jig which allows precise aiming of the collectors at the sun's track. Both insulated and non-insulated configurations of each collector design were built and tested. Both solar tracked and stationary mountings were used for the flat plate collector. The concentrating collector requires tracking for it to function.
As a part of the tests, a new approach is presented for making an insulated concentrator collector as an extension of the design presented in my plan book How to build a tracking parabolic solar collector.
This is a work in progress and the entries as written in this blog probably aren't in the best order to read about my testing project. The index below ties together the related posts in the recommended reading order.
