We got the Solar Screens installed in early June 2011.. Here's the bill since last year..
But, it's going not going to be real useful, since we installed a 24,000 BTUh
Sanyo in the room on 10-10-2011.

This summer, we turn on both units when we need some cooling..
The Den has never been used so much this past winter and this summer.
My guess is our 42" Plasma (400 watts) has never been on for so many hours.
It's gotten 3 years of use during the last 9 months!
