Sunpower C50 Solar Cell
Super light, super thin, approximately 0.6 volts output per cell. When you see 3.2W, 3.4W, 3.55W, etc, the variations typically correlate with the amount of surface imperfection. The 3.2W are the cheapest ones and if you buy from China, etc, chances are you're going to get chipped panels, that others sell off as "B-grade", etc. These are much nicer with an excellent surface rated 3.55 W.

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.

Buy as few or many as you need, there is no extra shipping charge for any quantity. 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, etc) on both sides.
Features 3 tinned copper connection points per polarity. ROHS compliant.
Extra care will be taken when shipping you the cells to ensure they arrive without damage.
