Sounds like a great idea! For those of you who never spent any time in Lancaster, CA, let me point out that every vacant lot was a meadow of tumble weeds when I lived there for four months as a child back in 1975. Our family only had one car, so my mom, my sister, and I walked everywhere while dad was at work. Perfect environment for a PV array in the high desert. Take a look at the place in Google Maps Street View. I still see plenty of tumble weed pastures... Let me also be the first to point out that the 1.0kW-1.5kW minimum array they are talking about is not a $10k-$25k investment. Its SEVEN 235W panels attached to SEVEN enphase 215W micro-inverters = 1505W. For reference, you can order a 1kW Grape Solar system from Lowes for $2745, and theoretically meet their minimum proposed requirement of 1kW (DC). If another flashed hole in the roof (for the one electrical conduit), an extra breaker in the panel (because you can put seventeen 215W inverters on a 20A 220V breaker), a dozen lag bolts drilled into the rafters, and the rack for six panels equates to $15k in your mind as a building contractor, then keep paying your electric bill! (the power company needs more sheep to go along with their 5% annual rate hikes and their minimum 10% return to shareholders). For those of you saying "If you face the house properly, and insulate...", Great concept, but I've done land development for residential tract housing in my lifetime, and not every lot can have awesome southern exposure if you expect to meet modern development standards using curvilinear streets. If you want to lay every neighborhood out like the 1940's-1950's on a simple rectangular grid where people fly down your street at 80mph, go right ahead, but don't expect to win awards for curb appeal. I don't understand why the government hasn't mandated higher efficiency appliances and PV before now, in the places where PV makes sense. Nobody wants a nuclear power plant in their backyard. Where I live, nobody wants the new natural gas fired power plant in their backyard, but everyone wants to run their A/C and the government thinks every road needs street lights. If they are going to keep building houses, schools, and shopping centers, the power has to come from somewhere... Every new school should have PV on the roof in places where it makes sense. Otherwise, you're just paying my tax dollars as dividends to the power company shareholders.
