Sunpower Maxeon 60 Flexible MONO Solar Cells The best cells for DIY panels

Description: SUNPOWER MAXEON 60 FLEXIBLE SOLAR CELLS These are the BEST cells for DIY panels. Sunpower flexible cells are the EASIEST cells to work with. Sunpower solar cells have the highest efficiency ratings because all connections are on the back of the cell. More power out of a similar footprint. I've sold thousands of solar cells to the DIY market in the last 10 years, when Sunpower came out with these flexible cells it was a game changer. No matter how careful you are handling normal mono or multicrystalline cells you will break some. Sunpower flexible cells will take So much more abuse before cracking, when you weigh the cost of normal cells and how many you will break VS. flexible cells and the added cost per cell you will still make out better buying flexible cells from the start. I strongly recommend using the Sunpower "Dog bone" tabbing pieces. These are manufactured specifically for Sunpower for use on these cells. If you chose to not use the bones bridging cells can be done with tabbing wire( wider is better) or buss wire. A rosin flux pen is also highly recommended for easier soldering. Grade -B, I see small scuff marks on some of the cells this will not affect performance. the cells also have a cloud like pattern, some have fine scratches and a few have fingerprints. I had a real hard time getting any good photo of the scuff marks. 3.34 watts per cell21.8 % eff..574 volts per cell5.83 amps per cell5" x 5" ( 125 x 125 mm) 36 cells wired in series in your panel will be a 20.6 volt panel at 5.83 amps = 120 watt panel. Cells rated using the STC system the standard system used in all solar cell and solar panel manufacturing. ( Standard Test Conditions) google it. Google Solar STC SHIPPING: One flat shipping cost no matter how many cells or cells and bones you buy, the more you buy at one time the more effective this flat rate is for you. The cells will be packed in bubble wrap inside a box called an "indestructo box" these are expensive strong boxes. Photos:main photo: 4 fronts, 2 backs,1 tabbing bone2nd photo: Close up showing (-) and (+) sides of the cells + one tabbing bone between them.3rd photo: I tried to get the skuff to show it is so lite it would not pick it up.4th photo: Showing slight discoloration on the cell.5th photo: Tried to get the minor scuff mark it but did not show.6th photo: Part of the front on one cell part of the back another showing 2 of the 3 contact locations.7th photo: The backs of 2 cells showing where the tabbing bone will be soldered to each cell.8th photo: Just the front of a single cell.9th photo: Just one single tabbing bone.10th photo: Just 5 cell fronts. NOTE: these cells will make easily on the fronts , do not lay anything on the cells , always use latex or latex free gloves when handling. ALSO I include a 4 page print out with many hints and instructions. also a schematic I made for a 36 cell panel made out of 3" x 6" cells this schematic is not made specifically for these cells but it is a great visual aid and will really help understand what your end result will be. the schematic clearly shows the buss wire connections connecting cell string to cell string.
