Looks like Phoenix is scheduled for rain for the entire week. This could have some say in whether or not our solar gets installed. This also means no global sun oven meals, I really can't say enough good things about that product. It heats to 325-350 in basically the same amount of time our indoor oven does. If I really pay attention to moving it with the sun every 30-60 minutes, it will get up to at least 375. I'm not sure how much of a difference ambient temperature makes, but in the summer it will be 60 degrees hotter outside than it is now. While it's not cheap (around $225) it's nice to know that it's made in America with non-sweatshop labor and that a portion of the proceeds go towards providing solar ovens to people that need them in parts of the world with less money.
Mikey- Our utility (APS) is paying $15,120 towards our 5.2 KwH system. If I remember correctly, it's not just a straight $3,000 per kwh, it increases as your system size increases. (I think it was $12,500 for a 4.8 kwh system) Arizona has a crappy buy back policy. They will buy any unused electricity from you at the end of the month at wholesale costs, should you need more than you produce in a given month you buy it from them retail. Alternatively, you can let your unused production roll over to the next month (and every year in April the slate gets wiped clean, so it's a bit of a use it or lose it). The latter is the route we've signed up for.
