[QUOTE="1krr, post: 2592204, member: 750"] That's kind of how we came at it. We didn't want to give up too much in lifestyle but really it's become a hobby all in it's own. If I were wanting to build a solar system on an existing home, I would first go through the house and figure out where the wallet suckers were. Like in our living room, we have two fans with 4 lights each but we use a single 23 watt cfl in one of those tulip lamps (what whatever they are called, the tall skinny ones that point up). It floods the room with indirect light and uses 7% of the power versus the original set of 40 watt incandescent bulbs did. We run that light a couple hours a night in the summer and for several hours in the winter every day. With incandescents on average, we would be comfortably over 1kwh everyday or about 30-35kwhs every month. I don't live in the city so I don't know about smart hours and such but just for simplicity, that could be 2-3 dollars a month off your bill. Repeat that 10 times through out the house and you've got real money. In terms of solar panels, that would be the difference of basically having a large panel and a healthy chunk of battery pack and inverter expense dedicated just to running those lights as much as we do. At today's prices for solar, that change in the living room would account for about $500-$700 worth of gear I don't have to buy/support just in the living room lighting. That's basically a new midrange rifle/pistol every couple of years with some left over for break in ammo for doing really nothing. There are other things too.
