Ben, I absolutely agree with the solar investment, that is why - next week, someone will come to inspect my home to establish whether he wants to make a bid on delivering me a system and I have already received a bid from SolarCity. Three in fact - one for pre-buying the electricity, one for post-paying for electricity and one for leasing the system. IF I go with them, then pre-buying the electricity looks like the better option, probably because it offsets their borrowing money, so I get a discount for avoiding their interest. All of them make some sense, especially seeing that the last year our electric rates have gone from $0.10 to $0.16 for the base tariff (and higher for the higher tiers) so, pre-financing a fixed electric rate makes a lot of sense, similar to getting a fixed rate mortgage, but with solar you are *earning* money at an increasing rate!

Tesla is including a ten-year warranty, meaning they're going to have to typically be nearly as good after 9 years and 364 days as they are new (presumably within some sort of specified degradation, such as 80% capacity). And Tesla's vehicular batteries are significantly outperforming expectations. The resale value of these units might not be anywhere near $10,000, but they'll still be doing the job you bought them to do and will likely continue to keep doing that job for at least as long as a typical mortgage. And if, in ten years, you can buy a comparable battery for, say, a mere $1,000? Well, then, we're _all_ that much wealthier. That's the great thing about alternative energy investments: barring complete loss, you basically can't lose. With my solar panels, I effectively pre-bought several years worth of electricity at then-market rates. Everything after that is free electricity. If rates go up, I win even bigger because I'm not spending that money. Rates aren't going to go down, but, even if they do, that means that other goods and services made using that electricity will be cheaper. My own payoff time may be theoretically stretched out...but that's already money under the bridge and I was happy to pay what I felt was a fair price at the moment. b& _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org For EV drag racing discussion, please use NEDRA (http://groups.yahoo.com/group/NEDRA)
