Jesse, The map is in degrees C not F and it is for the mean extreme minimum drybulb temperature from the ASHRAE Fundamentals 2009 edition.
It is a statistical lowest expected temperature for calculating the maximum voltage of a PV array.

It was -36.5 yesterday in Tower, the record low temp in Tower is -60F, that is not wind chill temp, it was -60F. Maybe I was reading it wrong, but check that out..... Jesse Sent from my iPad!!!

Thought I'd run it by the list to see if there are any changes you'd recommend (probably best if you reply to me off-list). If you zoom out too far, it takes a while for the map to load- and since I'm sending this out to 300 people (or whatever) it may be a bit slow for all of you who click this link at 11:10am ET today... > http://www.solarabcs.org/permitting/map/index.html > > Hopefully this proves helpful for you when you're calculating VOCs in new geographical areas.
