This is in the US. At $0.64/watt you're pretty much paying retail at single unit volumes.

At signaturesolar.com you can buy made in USA panels for $0.37. If you go wholesale, I've seen them as low as $0.26.

SurplusSolar had prices in that range as well. For my build, I did go with very nice panels (lg445n2w-e6) so that factored into the higher price for sure.
