The most abundant source of fuel in our entire solar system is the sun. Knowing how to build a solar panel for your home or business will let you tap into a power supply which will, scientists predict, still be going strong 4 billion years from now. If that doesn't sound like a permanent solution to soaring energy bills and dwindling fossil fuel supplies, there isn't one!
The first thing factor to consider in learning how to build a solar panel is whether you live in the northern or southern hemisphere. In the northern hemisphere, for example, solar panels for homes should face south in order to capture the maximum amount of sunlight each day. If the roof of the structure on which you'll be installing your solar panels doesn't face south (or north in the southern hemisphere), you can simply attach your solar panels to poles that have been installed in a location which does.
Learning how to build your own solar panel, as long as you have the basic carpentry skills, is actually quite simple. Begin by gathering your tools and parts. If the parts aren’t available at your home improvement store, you won't have any trouble finding them on Amazon

When purchasing your solar cells, figure that 80 of them will normally 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 instance, 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 direct sun. Then cut your plywood to the dimensions large 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 cut it in whatever shape you desire 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, start working on the solar cells.
Begin 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 adhere completely, and your wiring will be connected correctly. Then you’ll connect the solar cells to each other. Here’s a great video explaining the voltage testing, flux application and wiring processes you’ll do as you build your own solar panel:
