600 W, 24/7 is 14.4 kWh/day. You guys get hosed on electricity. I pay $0.12/kWh in the top tier, slightly less less for the first few kilowatt hours per day.

At California rates of $0.24 per kWh (which many people pay at only the third of five tiers of rates) that is $62 per month. Or $745 per year. With tax credits and rebates, it doesn't take that long to amortize one's net investment. Also, 14933 kWh from two sets of panels over three years seems pretty puny. With one set of 20 panels we generated 4400 kWh in one year--but I realize that this is not Connecticut either. This won't change the world, but it saves money and if everyone did it, it would make a worthwhile change.

I suspect, they have relatives in this town then. The insolation here is 160W/m². Some time ago I published this observation: <West Hartford's solar panels installed on two highschool roofs produced 14,933 kWh of electricity in about three years. This means that the panels generated average power of 570 W, enough to keep almost six 100 W lightbulbs lit.> Amazingly, the flood of disapproving responses ignored, all of them, the basic fact that powering six lighbulbs for 3 yeas is not going to make any difference to anybody, not even the schools, nor the U.S., nor will it impoverish the sellers of "foreign oil." Impossible people to deal with. I guess it is a religion with them. Do not take our faith away with just plain facts. Well, not all of them are idealists. Many entrepreneurs I know are in it because "someone will spend the budget anyway" a budget approved by ignorant politicians. "So why not me." Stan
