Consumers can purchase both new, or used prophylactic cells from websites such as eBay. Used cells are reasonably priced, while still being able to function properly.
Cells are often dipped in wax; this prevents breakage during shipment. To remove the wax, simply place it in cool water. Heat the water until it is hot, but do not allow it to boil.
The next step is to put the cells in a bowl of soapy water, and then finally, in a bowl of clear water. Place cells on paper towels and allow to air dry.
A panel is basically a shallow box. In this example, a 3/8” piece of plywood is used. Place 3/4” wood trim around the edges. This panel is divided into two, separate, sub panels; this is accomplished by adding another trim piece down the middle.
Glue, and screw the trim pieces into place. Drill small vent holes, along the edges, to allow moisture drainage. A peg board works perfectly to attach the cells to, and this is cut to fit and placed into the sub panels. The last step in prepping the panel is adding paint, to help weatherproof the wood.
This will hold 36, 3 X 6” solar cells. Begin by drawing a grid pattern on the peg board; this will make installation easier. Place cells upside down on the grid, and solder together in series. The negative tab, from one cell, will be soldered to the positive tab of the next cell.
Continue, until a string of six is complete. Three strings of six will make half a panel. The middle string should be rotated to allow a series connection.
Gluing the cells on the board, correctly, can be tricky. Place a small drop of silicone to the backside, of each cell. Flip the string of six over carefully, and place on the grid. Gently press down on each cell in the center where the glue was placed. Be sure no to use too much glue.
Gluing too tightly will cause cracking to occur when the cells and board expand during hot and cold weather.
Copper braid, regular wire, or tabbing material can be used to connect one string to the next. Use existing vent holes and slide the wires through to connect the two sides together.
A blocking diode in series is, then attached, near the top of the panel and glued into place with silicone.
Diodes prevent the panel from discharging energy during the night, or during cloudy days. A piece of plexiglass placed over the panel will help keep moisture out.
Learning how to make your own solar panel can be interesting and fun. The energy saved will be well-worth any time spent on construction. Homeowners will see significant savings on monthly utility bills.
