I finally had a little time to review some of the links posted previously. Very interesting stuff. And yes, it appears that some prices have come down. As an example - on of the links that BG posted states that you can by a pallet of 30 panels that are 224 watt panels for less than $18,000. Its a start. From most sites that I have read, the payback time is still from 14-16 years, but most panels have some sort of warranty to 25 years with a life span expected to be around 30 years. So basically in 30 years you "should" be able to double your investment (this assumes that electric rates hold steady, and we know that ain't gonna happen). It is food for thought. I personally think we are on the verge of cost and efficiency breakthroughs on the new panels coming out. I may kick myself, but I think I am still gonna wait a bit. I am betting on the same trends that we have seen with computer pricing or flat screen tv's, etc. The first ones are slow, clunky and expensive. With each generation they get better and less expensive. I would love to see the day that Home Depot sells a plug in grid tied 5kw system for 2000 bucks. YEEE HAWW.
