Read this article to learn how to build your own solar panel.

No energy source created by humans can compare to the sun, which all life on this planet depends on for survival. Solar energy is one of the most practical and economical forms of energy when we know how to take advantage of it. By installing solar panels in your home, you can have a very practical and inexpensive form of energy that has many uses.
Using a solar panel system means you will be self reliant for your power, so you won’t need to rely on the public power grid, which is an excellent benefit. This means that you will be able to greatly reduce your electricity bills and even completely slash them in some cases. In addition to this you may also be able to get paid for any extra electricity you produce, as the government purchases it in some areas. But even if this doesn’t happen where you live, you’ll still make big savings from installing solar panels.
The container for your solar panel is simply a box with a Plexiglas front, which will allow sunlight to flow in but will ensure that the cells are protected. You will glue your solar cells to the substrate, which are the strips of wood that you glue to the inside of your box. You should only use a dot of caulk in the center of the cell. To avoid damaging your solar cell consider using a single dot of silicone caulk to keep the wood free of encumbrances. To make sure that no moisture gets in make sure that you fill the hole with caulk after you have pushed the wires through. Then, screw your Plexiglas on and mount it where you want.
A nifty device that sits between the battery and the solar panel is called the charge controller. To make sure your batteries do not explode, or receive the wrong level of voltage while charging, you need to have these devices hooked up. To make sure that the electricity does not flow backwards, these units are also necessary. They also act like a resistor not allowing the batteries to be overcharged.
All it takes to build your own solar panel is a little skill with the tools. With your solar panel up and running you could be powering your own home with sunlight.
