Anyone have a favorite vendor source for >21% efficient PV panels they'd like to share?
I'm looking at various commodity 60 and 72-cell modules made with 4.95 to 5.0W high efficiency 156mm monocrystalline cells, but the Sunpower mono stuff is still better in STC watts per square foot. 60-cell x 5W = 300W 72-cell x 5W = 360W Of course, willing to pay somewhat of a price premium....
