DIY Solar Panel Kit
This Kit is a Great way to learn how to build working high quality solar panels without investing a lot of time or money. Once you have learned this great new skill, with the right materials you could generate your own power forever!
What sets this kit apart from the rest is the comprehensive and detailed instructions...3 videos, 32 pictures, and 35 pages of detailed step by step instructions in cd format.
This is what you get in the kit:
- 45, 3" X 3" ( 76 mm x 76 mm) Square, Solar Cells (Rated at 2 amps each) - These cell are easy to work with. We give you 45 cells because handling cells is tricky, and you will most likely break a few. No worries! You will only need 36 to complete our suggested panel.
- 25 feet of tabbing wire (22.5 is needed) - Flat, skinny wire used by professionals to connect cells together. You need 6 inches for each cell, so this gives you a bunch extra to experiment with 48 inches of bus wire Wider, thicker wire used as a common connection point for multiple connections. The more current flowing, the thicker the wire needed.
- 2 feet of 18 gauge black and red wire - You will attach these wires in the junction box.
- One blocking diode: 3 amp - A blocking diode is a semiconductor device used to stop the flow of current from one direction, but allow it in the opposite direction; a one way street sign for electricity. When the panel is making electricity, it will flow into your battery and charge it. However, if the sun goes behind a cloud, the charged battery would try to flow backwards into the panel, draining the battery and/or potentially damaging the cells. The blocking diode prevents this back-flow from the battery.
- 50 spacers - Keeps the glass front and the plastic back from putting unwanted pressure on the cells.
- One Rosin Flux Pen - Helps adhesion and solder flow.
- One roll of leaded solder, 170 cm length - This is leaded solder, which has a lower melting temperature and is easier to use (in my opinion) than the "No lead" type.
- One basic Junction Box - Attaches to the back of the panel for connecting wires from inside and outside the panel.
