When I was installing my own solar system last July I took a laser pointer thermometer gauge thingy up the ladder with me and started pointing it a various surfaces. I have a picture of the thermometer pointing at my medium grey flat concrete roof tile and the number 165 is reading on the gauge!! My feet weren't tingling because of "falling asleep",.....they we're burning!! I am so going up on the roof and painting a tile or two white and reporting back to you guys on the delta of the temperature sensor.

Blue Skies,

Jeff
