Cheap solar cell sources, recommendations?

I have located tabbed solar cells at $0.61 a watt, however you have to buy a metric uber buttload of them. Fine if I was planning on building a whole house array

Solar Cells : Solar Panels Direct, Powered by Nature!

Are there any inexpensive sources of solar cells that are sold in moderately small amounts? I have tried the Locate a dealer for chipped/offspec cells without success.

I also am looking for inexpensive supplies as well to attach these into a custom voltage array for my 48v and 72v electric cars to work as a trickle charger/battery maintainer when it sits.

Thank You
Ryan

This is a bit of work and hasn't worked that well for me (I'm in Canada) however it has worked for buddies living in the Southern US states.

Call the municipal governments in charge of road works. It sounds weird but the majority of those signs that inform people construction is up a head have a solar panel lashed to them and most public works operate with the same type of "evergreen" policy the IT industry does. Every three years they replace the panels with more efficient panels. My understanding is it's possible to get them used for around .31-.37 per watt and the panels themselves are 400-600 watts.

Only problem I've run into I would have to haul ass from Ontario to Florida with a very large truck because it's not like you get to buy them a single panel at a time. The municipalities are more interested in dumping a couple hundred at a time. I suppose if you organized a keretsu (Long standing Japanese business idea of many small businesses buying together to make a big purchase to lower costs). That would make it way easier.

Also living in Canada, coming across the border I would get the privilege of paying duties and taxes on the deal so my per watt cost wouldn't be worth the drive. Because the govie gets their cheddar my ROI stretches because the cost per watt doubles. Plus Ontario Hydro has some really, really, really, dumb policies on person energy. If we make electricity, we have to sell it back to Ontario Hydro and get to pay a fee for the privilege.

Good taste or good flavor, I'll let the philosophers decide.
