Based on current rates and guesstimates of installation costs from my rural co-op power supplier, it will cost about $8k to bring in power. This would be a buried line (wouldn't have it any other way). I spent some quality time caluculating this stuff 2 years ago when we purchased the parcel, so alot of this is by memory...but...my preliminary studies of solar power, totally off the grid, indicate the basic power source would cost would come in around $15K. This would include PV panels, batteries, inverter, and supply wiring for a medium sized system (4000 watt, IIRC...?). A decent sized (10 - 12Kw) propane generator is another $5k. So, in round figures, call it $20k. Now, consider the periphery stuff. The special refrigerator, special wiring and lighting fixtures if you want to operate at 12v for efficiency. I can't begin to remember the list of unusual changes that would be required...but it was all based on low energy draw. This is why I would really like to hear from somebody that is doing it. Any PB'ers out there that are off the grid?
I agree, the biggie for me was the need for A.C. This would require generator operation. Swamp coolers are definitely OUT.
The last big drawback is the market-ability of a home product that is powered in this manner. Like all investments, you gotta consider the "what if I sell it?" scenario. I gotta believe that the market segment narrows considerably for a solar powered home. I think that is probably the final nail in the coffin.
Now, what about solar as supplementary? This might be an option. There are some government rebate programs for the purchase and installation of this stuff. You guys in CA. have generous incentives. This might be the way to go. Any players in this arena?
