Solar Panels for Electricity
http://www.AsYouCanTrust.com/solarpanels
Cut your sheet of plywood to fit the dimensions needed for your array of solar cells.
For an array of 36 solar cells of 3 inch by 6 inch mono-crystalline,
accounting for room in between the cells,
you will need a plywood sheet of 45 inches by 24 ¼ inches by 3/8 inch thick.
Please note that you must use cells of the same size–don’t mix sizes on the same panel.
Using the wood glue and wood screws, mount the 4 strips of ¾ inch by ¾ inch wood along the outer edges of the plywood.
This will provide a shallow panel box for the solar cells.
Drill holes in the bottom rail of the ¾ inch strip for ventilation,
pressure equalization, and to allow moisture to escape.
Holes must be in the bottom rail only.
Run a strip of vent tape over the holes to prevent dust and bugs from entering the panel.
Cut the peg-board to fit within the panel box.
Cut plexiglass to the same dimension as your sheet of plywood.
The plexiglass should rest on top of your ¾-inch railing.
The plexiglass should NOT lay inside of the railing.
For now, set the plexiglass aside for later use.
It will be attached after the solar cells have been constructed.
Paint your panel box and peg-board with exterior latex paint.
This will aid in protection from outdoor weather.
Let paint dry for 24 hours.
