Because of the significantly better efficiency of a Endless Solar evacuated tube collector in harnessing the sun’s energy, you can locate your system on a roof area facing north-east or north-west with only minimal reductions in efficiency (2% to 4% loss) or on a west or east facing roof (6% to 10% efficiency loss). Even if the only unshaded place to mount the collector is on a south facing roof, it can be mounted on a reverse frame facing north. However, the best place to locate your solar collector is on a north facing roof with a slope of 20 to 45 degrees.
