Yes, you can find most anything you'd care to know online - Anything I could tell you would be pretty out of date by now I'm afraidRobbW said:Don said:A more practical approach if what you really want is to just make enough juice to power your car is to install a solar water heating system. Using the sun to heat domestic water instead of using electricity (or some other fossil fuel) can save you enough electricity to power your car . . . . and make you essentially as 'green' as if you had enough solar panels on your carport to charge the car. I installed such a system with a 40 sq foot collector and it saves me about $40 to $50 per month. It provides ALL of our hot water for about 10 months each year and a sizeable portion of it the other two months
That sounds interesting to me, Don. Do you have any readily available links with information I can look into? Of course, I can Google it later when I have more time, but if you have some good sites you consider extremely helpful, I would love to get those. Thanks.
I designed and built my own from scratch about 7 years ago. I bought all high quality components and used 1/2 inch copper tubing to plumb everything up - Lots of soldering, but then nothing I hadn't done before. Copper tubing was lots cheaper 7 years ago than it is now, I can tell you!
All in all, I spent about $3,000 but then the IRS gave me back about half of that the year I installed it. Even at $40 per month, the remaining $1500 was quickly amortized over the next 3 years, so it's been making me money now for almost 4 years - It's paid me back lots more than I paid for it, so it's really an 'investment' at this point
Having a system like mine professionally installed would probably run about double what I paid, so I guess it would be pretty important to know you're going t stay in the same house for quite awhile. Your payback would probably be closer to 10 years, but it would still be much faster than a solar PV system
Unlike solar PV systems which keep getting better and better every year with changes in technology, solar water heating systems have been pretty well perfected for a long time, but unfortunately, the prices aren't coming down. The same 4 X 10 panel that I paid less than $1K for 7 years ago now sells for about $1350 . . . . probably because it's chock full of copper! Why is it that only electronics get cheaper as the years go by?
