Here's and intereresting one, not written by the late great George Harrison, but by the Energy Saving Trust. A UK and Ireland field trial of solar water heating systems. www.energysavingtrust.org.uk/Publications2/Generate-your-own-energy/Here-comes-the-sun-a-field-trial-of-solar-water-heating-systemsThere's a throwaway reference to flat plate and evacuated tubes having a "similar annual energy yield", but unfortunately the trial did not compare the monthly distribution of the energy yields of these two types of panel. This would have shown vac tubes more efficient than FP in colder/marginal months and less efficient than FP in the peak solar months. Despite this missed opportunity, it is a good read for anyone who is bored.
