cheap, but how long will they last, what kind of environmental standards were they made under, what kind of working conditions were the workers under?
Name brand cells, that were made in well known factories with employs who get health care are in the $3.25-3.50 per watt range now and those are cells that are in a frame, between layers of tempered safety glass and come with a 25 year warranty and should last 50+ years.
Individual cells like that are great for small projects but to power a house why not get something that you can also get the tax credit for (those don't qualify!) and you are suddenly down to just over $2 per watt.
