The most redundant source of fuel in our entire solar system is the sun. Understanding how to build solar panel for your home or shop will let you tap into a power supply which will, scientists believe, still be going strong 4 billion years from now. If that doesn't sound like a permanent solution to rising energy bills and vanishing fossil fuel supplies, there isn't one!
The first factor to considerin knowing how to build a solar panel is whether you live in the northern or southern hemisphere. In the northern hemisphere, for instance, solar panels for homes shouldface south in order to capture the highest amount of sunlight each day. If the roof of the structure on which you'll be setting upyour solar panels doesn't face south (or north in the southern hemisphere), you can just attach your solar panels to poles that have been {installed|set up]in a position which does.
Understanding how to build your own solar panel, as long as you have the basic carpentry ideas, is basically quite straightforward. Begin by gathering your tools and parts. If the parts aren't available at your home improvement store, you won't have any trouble getting them on eBay!When purchasing your solar cells, figure that 80 of them will usually produce 100 watts of electrical power. You'll use your volt meter to test the solar cells individually, making a record of the voltage each produces. If you wanted to charge an 18 volt battery, for example, you'd need a panel with 36 solar cells producing .5 volts each.
Determine how much power you need from each of the solar panels you're going to build, and remember that you'll need more solar cells in areas which don't get a lot of exposed sun. Then cut your plywood to the dimensions big enough to fit the number of solar cells which will be on each panel.
While the most common shape of solar panels for homes is rectangular, one of the advantages of deciding to build your own solar panel is that you can morph it in whatever shape you want to fit where a rectangular panel won't go.
Once all your plywood has been cut, use your paintbrush to apply the UV-ray protective varnish. While you're waiting for the varnish to dry, begin working on the solar cells.
Start by using your Rosin flux pen to apply flux to the bus strips on your solar cells. This will ensure that when you solder your tab ribbons to your solar cells, they will stick totally, and your wiring will be connected correctly. Then you'll connect the solar cells to each other.
When all the cells for you solar panel have been connected, using as little silicon as you can, affix them securely to your plywood panel. You'll have two unattached wires hanging from the connected solar cells, requiring that you drill two holes in the plywood and feed the wires through them. Then seal any gaps around the holes with silicon.
Next you'll make a "frame" for the panel, because you need to cover the solar cells with Plexiglas. Adhere the frame to the plywood with more silicon and wood screws, ensuring that it's waterproof. Then secure the Plexiglas to the frame, first with silicon and then with screws. Be sure, however, to drill the screw holes into the Plexiglas before attaching it to the frame. Otherwise it could crack.
Inspect every inch of your solar panel for gaps which could allow moisture to penetrate it. If you find any, no matter how small, seal them with your silicon. Keep in mind, however, that even as tightly as youve sealed it, moisture can still accumulate in the panel's interior. So the last thing you'll do is drill a small hole close to the bottom of the panel but away from all the wiring. This will allow air in to the panel to keep moisture from building up. By placing the hole at the bottom of the panel, you'll also keep rain from collecting inside!
