GOB...these solar systems really aren't cheap ya know. About 5 bucks a watt(or more) installed. But the life expectancy is over 20 yrs for most and payback is not all that long. Especially at your lattitude. You would probably need at least 4000 watts of solar panels to get ya some relief from those high electric bills. Oh and plant a few of those fast growing Hybrid poplars in front of the house. They grow 15 ft a yr. and give good shade
And don't forget the possible tax write offs etc
