Solar hot water panels come in two types. http://www.yougen.co.uk asks whether flat plate or evacuated tubes are best. Gabriel Wondrausch of SunGift Solar gives us the low down.
Its all about the ambient temp and inlet temp..has nothing to do with you are saying. The correct answer is to plot it on a chart and see which one is more efficient. For domestic water heating the flat plate will be more efficient.

Do they pay you to say this stuff? LOL. ETCs break in hail and lose their vacuums. They last 2-15 years, whereas FPCs last 30-100 years. That ought to settle it right there, but just in case some silly person out there is still worried about performance, FPCs outperform ETCs up to 120 deg F (67 deg C)... ABOVE AMBIENT TEMPERATURE!!! That means if it's 32F (0C) outside, FPCs will STILL outperform ETCs up to a temperature of 152F (67C.)
