I just came across some information about a new technology coming on the market called CIGS. It is a non-silicone based Solar cell that is said to be cheap to manufacture and may even become competitive with the cost of utility based electricity production within 5 to 10 years. Basically, it is a piece of plastic sheeting with 4 metals sprayed on it in a very thin film (Copper, and 3 others). It is not as efficient as silicon, but is much cheaper and easier to manufacture.
I also found some used solar panels for sale on Craigslist for $50-75 each, but the ads were cryptic and did not specify weather they were for a water heater or electrical panels. If I had the cash (and they are electric), I would buy 1 or 2 of them plus an inverter to experiment with. If it worked out, I would source some golf cart batteries and more panels to try and run some of my summer A/C needs off of it instead of paying my local utility. It may not pay all of the bill, but if I could cut $40-50 a month off my electric bill it would pay for itself in a short time.
