how to build your own solar panel?
first step: Acquiring the solar Cells
The primary cost incurred when constructing a solar panel is the cost of the cells. A 3" x 6" mono solar cell costs around $6, and the average solar panel contains 36 cells, coming to a grand total of $216 per panel. Most solar installations will require multiple panels. Although it is still cheaper to purchase the solar cells in bulk and construct the panels yourself than purchasing a pre-fabricated panel, you can drive the cost down even further by purchasing slightly damaged solar cells. Slightly damaged cells will have small cracks or chips on their surfaces, and although these defects will affect the final energy output of the panel, the loss will not be significant. Despite the fact that the final product is not significantly inhibited by slightly cracked cells, manufacturers will not use them, and they can therefore be acquired quite cheaply from the manufacturers and through auction sites such as eBay. Purchasing lots of slightly damaged cells can drop the cost of a solar panel by up to half.
Second step: Building the solar Panels (solar module)
The panel's frame is basically a shallow box about 3/4" deep, in which the cells are installed as an array and covered by glass or Plexiglas. A basic frame can be constructed by cutting a 3/8" thick piece of plywood to the dimensions of 45 3/4" long and 22 1/4" wide. Attach a 3/4" x 3/4" wooden border around the perimeter of the plywood to create a frame. Install a piece of Masonite pegboard inside the frame and attach the cells to it.
Once this frame structure is finished, attach the cells to the pegboard and solder them together in an series, touching each solder point to form the solar cell array. Be sure not to place too much pressure on the cells because they are prone to break. It is always a good idea to have some extra cells in case you do break a few. Once the cells are wired together, attach a blocking diode at the end of the series to prevent your battery from discharging at night. After the blocking diode, add whatever type of electrical plug you will be using to complete the circuit. Secure the Masonite board and the solar cell array back to the frame and double-check that your connections are all good. Once you are sure the wiring is right, cover the frame with a sheet of Plexiglas, and your solar panel will be ready for use.
