I realize this will not affect most of you, but I thought I should let you all know what I found. My strips have been up on the south side (sunny side) of my house since the middle of October, in that time the tempurature outside has swung from 10C to -15C a number of times. This heating and cooling has caused a few issues with my set up including: Pulling the strips through the Ty-raps causing sags. Not a big issue but something to be aware of. And the bigger issue is a couple of the soldered joints in the middle of a few of the strips have broken.
