You can buy this solar cell individually. Usually we prepackage them in to 36, 50, 72, 108, 150, 200 pieces and sell them as a bundle. But this one you can order any number of cells you want. The unit price is higher because people usually buy a few as samples to find out how well they perform and how they look. We are the largest Everbright Solar cells seller in the world, so we are very confident in the solar cells that we sell.
This batch of solar cells came from the factory in Devens, MA directly to our warehouse in Silicon Valley just a few weeks ago. This set of new 3"x6" solar cells are string ribbon multi crystalline cells, and have the smallest carbon foot print - they waste the least silicon in making these cells.These newest cells have a little different look from the other cells are still being made in the largest quantity in German factory (The German factory uses all American technologies and equipments, and it's adding another new production line going live this year). The front of the solar cells looks similar to the traditional multicrystalline solar cells in that they show the borders and shapes of irregular crystal formation. In terms of output they may be slightly better, but in any volume production you are going to have cells with varying levels of power output. The cells are the original factory standard cell size, not other sizes cut by using home made tools which could damage the cells during cutting process. The cells have never been used or soldered, and are not recycled from badly made panels like some factory installed tabbed cells are. There are no tabs on these cells so you can start from scratch and get experience in making solar panels. In our listings, if we don't describe them as 'chipped', then they are considered to be our category A cells, although very tiny defects or blemishes could exist but they don't affect power output. Our sorting team tries to do as good as a job possible to categorize the cells. Almost all of customers have been very happy with the solar cells that we shipped in large volume. If you think the solar cells don't meet your expectations, send them back within 7 days for a complete refund or replacement, because we understand that in large volume order processing, some mistakes do happen and the important thing is that we are willing to rectify them and we need to be given an opportunity to fix rare mistakes when they do happen. From the enormous number of cells that we shipped this past couple of months, returns have been essentially negligible. We will keep rolling out new products and categories at great prices and those who mistreat us will be excluded from our new offers.
