[QUOTE="Exfarmer, post: 7928119, member: 1951"] No they do not generate heat, it is just the same as being behind a darkened glass window, but the level of heat will build up and not be lost the actual amount of heat available to harvest would be very small. It is just that on a regular install sitting a couple of inches clear of the, a draft builds up behind the panels exiting at the ridge as the warm air rises and maintains the panels at ambient air temperature. The amount of production lost is not that great but over 20 years is considerable. It does also have the advantage that it helps keep the building cool as this solar heat is absorbed by the roof anyway without the panels [/QUOTE]
