Untabbed 3x6 .5v3.6a Evergreen solar cells DIY panel kit /wires flux

These untabbed 3"x6" Evergreen Devens solar cells Do It Yourself DIY solar panel kit contains 108 string ribbon multi crystalline cells made by Evergreen Solar, the all American solar company that has 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 Evergreen solar's 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 category A cells, though in small number of cells, very 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, and we are confident that they are the best cells available on eBay outside of Evergreen solar itself. Almost all of customers have been very happy with the solar cells that we shipped in large volume, although we must admit that in the eBay retail market there are some people who are just very very hard to please, no matter how much we bend over to help them. We stand by our products. 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. We will even pay for return shipping. 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.

The following is a little more details regarding this kit: (cells, tabbing wires, bus wires, flux, solder)

I: Cells:

The standard cell specifications are the following, though the individual cells can be above or below these standards.

Cell Specifications: Average Power (Watts): 1.75 Wp Average Current (Amps): 3.5 Imax Average Voltage (Volts): 0.5 Vmax Thickness = 200 micron = 0.2 mm Exact dimension: 3 1/4 inches x 6 inches, or 80 mm by 150 mm Weight: Just above 6 grams, or 0.2 oz.

II: Tabbing wires: $22 value - 110 feet of tabbing wires that Evergreen Solar uses to connect the solar cells. Cut them into 6 inch sections to solder onto the bus bars on the cells. You will get slightly more than 110 feet, but 108 feet is what you need to tab 108 cells.

III: Bus wires: $5.5 value - 11 feet of bus wires. Use them to connect them between the series and connect the tabbing wires ends to the junction box at the back of the panel.

IV: Flux: $7-$9 value - an easy-to-use flux pen that dispenses flux onto the bus bar or your tabbing wires without leaving a mess. It's used to aid soldering and bonding of the wires to the cells. A must have item.

V: Solder: $7-$9 value - a tube of solder to help you solder the tabbing wires and the bus wires together, or whenever you need extra solder.

Our standard package: 36, 50,108, and 150 solar cell kit. We do sell other quantities based on customer's request.
