I have a retired Army friend who lives in Albuquerque.  We physically visit back and forth from time to time.  A couple of months back, he was at my place.  He's not too technically inclined but does a lot of internet browsing.  He'd seen my ground mounted solar array and was telling me that such installations were a real eco hazard.  I ask why and he told me about an internet article he'd read stating that low mounted solar arrays like mine destroyed all life in the ground under them because of the heat given off by the back side of the panels. I said bull but he insisted the panels caused the earth beneath them to become super heated.  

Well, shoot!  I got out my laser aimed IR thermometer and we too took a stroll to behind my rear yard fence and to the panel array.  It was a blue sky blazing hot late summer day here in desert New Mexico and about 11 a.m.  We got out to the array and I measured the temp on the nearby earth in direct sunlight.  Reading was about about 118 F.  Then I measured the shaded areas under the panels which read about 85 F.  He was astounded.  I handed the thermometer to him, showed him how to operate it, and told him to wander about and take his own readings.  He measured the back side of the panels just over our heads and they were about 100 F while the ambient temperature was about 96 F.  I said, 'gee, the bottom of these panels are only 4 or 5 degrees warmer than the ambient temp.  Sure no super heating, is there?'  He had to agree and I reminded him to not believe everything you read on the internet--which too often provides a bumper crop of misinformation.

Ha ha! It has to be true if it's on the internet, right? [biggrin]

Some Mentalphysician's truth perhaps.  [rolleyes]
