Just about everything (within reason) has been done. I've been getting down to the last of the wall-warts.
One of the main reasons for this 'greenness' is the new Sanyo heat-pump that we just installed to heat our home this winter.

With this thing running up the NStar bill, we need to watch all of our usage.
I was thinking of buying 1 or 2 of the K60 panels to charge 12V batteries.
I've been looking at the Steca Solsum 5.0C 5A 12/24V Charge Controller
and wondering if it will handle the high DC voltage from a K60 panel.
$ 123.96 for a 60 watt charger isn't bad and that should be enough
to meet all my hobby and backup-lighting needs..
It can charge two 12V batteries in series, which is nice..
With two K60s in parallel, maybe I could use it to take some of the DC parasitic load off the line.
Items that are on 24/7 and use 12VDC..
Anyways, solar PV isn't going to be a big investment right now.
But, playing with some small scale stuff might be a good learning experience.
