Description: HEART OF THE SUN-SOLAR Sells many items needed to build your own solar panels, solar cells, junction boxes, tabbing wire, buss wire, solder, soldering irons, EVA encapsulation, rosin flux pens, PV WIRE connectors, and more. visit my store for a complete list. Not sure what you need send me a question and some details. Brian NEW! This is a mini experiment kit. You want to try building a solar panel but don't want to invest much. You get 50 solar cells 2" x 3" ( 50 mm x 75mm) .5 volts x 1.2 amps each. 36 cells would make a 20 watt panel. You only need 36 cells to make an 18 volt panel the standard size for charging 12 volt batteries. Note: some kits contain solar cells cut from 2 buss bar cells and the wide collector line will be more centrally located( main picture), SOME cells are cut from 3 buss bar cells and the collector line will be off set to one side( second picture) it will be random which type you will get. Also I use different brands of cells, the cells may not look exactly like the picture, you may see more of a crystal pattern. One(1) junction box One(1) 3 amp diode One (1) rosin flux pen( M G Chemical brand) A quality flux pen. 20 feet of tabbing wire( 6 meters) you only need about 16 feet( 5 M) , this is plenty extra. 2 feet of buss wire THIS KIT DOES NOT COME WITH INSTRUCTIONS Go to YouTube and watch 20 different videos on building solar panels while you wait for the kit to arrive. Instructables.com is another source. Instructables is also a great place if you want to try to fix anything, just type in your problem or other key words and there is a good chance someone has uploaded what you need, it's Awesome. The 2x3 cells are a nice size , not to big and not real small. this size gives them some body and you will not break as many as you would if the cells were smaller. A basic non-waterproof junction box to give your project a nice look and it is functional as well. Your diode will get mounted inside the J-box, you can attach wires inside the j-box and run then out to easily hook up to experiments. The j-box comes with instructions on the soldering and placement of the diode. A 3 amp diode is needed to keep any electrical source you are experimenting with from back-feeding the cells, this usually does not hurt the cells but will run down a battery for example. A rosin flux pen, the second most expensive item in the kit, the cells are # 1 of course. A rosin flux pen will make the job of soldering tabbing wire on the cells much easier. You just apply the flux by dragging the tip down the collector line before soldering the tabbing wire on. Just like if you were using a marker. The flux pen comes with opening instructions and some hints for using it. 20 feet ( 6 M) of tabbing wire, you solder pieces that are twice as long as the cell is, when you have done them all you flip over the cells and solder the tabbing wire from one cell to the back of the next cell ,repeating this process to connect all 36 cells together. 2 feet ( 61 cm) buss wire (thicker + wider than tabbing wire.) You run the buss wire from the positive cell to the j-box and from the negative cell to the j-box. Check out my other items! I have hundreds of other solar related items for sale.
