PV north facing in US [RE-wrenches]

[Tom Lane, Energy Conservation Services]

this is not surprising at all in mid summer-- however repeat  the test
between October 21 and February 21 you will  get almost zero on a north
facing roof under clear sky conditions   gator tom in the south below 35
degrees latitude a north facing roof will outperform a south facing roof-
we only install pool heaters on north facing roofs with a stipulation in
the contract that it only heat the pool from march 21 to october 15  gator

> Hey Jay. Right in your own back yard. Arcata H.S. installed two identical
arrays earlier this year with the partial intent to test north facing array
performance. One faces permanently south, and the other can be rotated north
(tilt angle unknown to me). The arrays were performing nearly identically
facing south. They recently moved the rotatable array north, and it began
out-performing the south-facing one! Go figure.

expect some real-world test data in the future.
