Just find the "B grade" 10-pack in the drop down menu when ordering. These are "the best" solar cells, unbelievably better compared to the rigid cells.
If you've worked with the regular mono or poly cells out of China, just think about how many you've broken! Or the headache of welding the backs of the cells in long strips. Another point that makes Sunpower so special - they (a) perform better in low light, and (b) pass current from other cells in the same series through a poorly lit cell with less resistance. This means you can avoid the use of diodes if you want (even altogether), and harvest more power in poor lighting conditions.
One more point - the voltage generated per cell is twice that of traditional wafers, so you can build smaller usable panels. Super light, super thin, approximately 0.6 volts output per cell. These are the best of available flexible solar cells currently on the market at an awesome price.
Unlike the cheaper "brittle" mono and poly cells, these have the distinct line-free dark blue look. AND they bend up to 40º and are super light, which is just awesome. The future is here, today! Used on the solar impulse electric airplane due to the amazing light weight of each cell.
These are rated at 3.6W, blemish-free "A Grade", no scrap, no B-Grade. This is the best solar cell bar none, and the best bang for your buck. No fingerprints, guaranteed no cracks, no stains, no blemishes. Best bang for the buck.
Recommended use with the 3-point dogbone bus bars to connect the cells to each other in series. These busbars are tinned copper 99% lead-free, made specifically for these cells. Ships from USA (not china) so you get it fast without damage. These cells must be handled carefully. While they are much more flexible than traditional cells (30° bend), they are also easy to snap like a cracker if you are not careful and bend them past their maximum tolerance, especially if bending parallel to the collector lines.Each cell is incredibly thin and light, and should not be used without protective coating (EVA, silicone, etc) on both sides unless you're using them in outer space.
