Why Solar Panels Work And What They Are Used ForThe future of solar energy is certain to be long and adventurous. Solar energy is "green" meaning it leaves no negative impact on the environment not to mention it is likely to be around for a couple billion more years, or so the experts say. Additionally, the fact that it's free, except for installation costs is another factor that will probably see many homeowners switching over to this form of energy source.
Solar cells are contained within boxes called solar panels. The conversion of simple sunlight by the solar cells is how they create electricity. Silicone material is used when creating solar cells, a material that will actually generate electricity when sunlight is applied. People that purchase solar panels need to buy a lot of them because each cell only produces half of a volt of electricity. There are many kits available and instruction manuals to show people how to make their own solar panels so that they can have free electricity as well. However, you do need to be handy with a soldering iron and a saw, so if you aren't really into DIY, maybe you should ask a friend who is for help.
This plexiglass cover is used to protect the cells from the elements as well as provide an inlet for ample sunlight for charging the cells. To attach the cells to the box, you will need to glue some strips of wood inside the box, also known as substrate, onto which you will glue the solar cells. Because the wood will shrink and expand with the weather, you should use a dot of caulk in the center of the cell. It's imperative that you avoid damaging cells by using a single dot of this caulk to allow wood to shift. Drill a hole in the box to feed your wires through, but make sure that you fill it with caulk when you are done to prevent moisture from getting to your solar cells. The plexiglass will have to be screwed on and mounted where you want it.
If you are doing all of this yourself, it's important to remember that a solar panel is essentially a set of solar cells grouped within a container, which you will need to create for your solar panels. Wood is the most widely used material for these containers although there are a wide range of other materials that can also be used. Your local hardware and lumber store can direct you to many types of woods available although the final choice is yours You'll need wood inside the box that can hold the cells separate as well as a plexiglass covering for the box. This type of opaque covering protects the cells from damage due to the elements while still allowing necessary sunlight to reach each cell. You'll need to have a hole in the box that will make it possible for you to get the wires pulled outside the box too. Once you mount the solar cells, you will need to do a bit of soldering to connect the cells to each other.
It only takes some skills with tools and anyone can build a solar panel. So, you can soon have your own solar panel up and running and you might even end up powering your entire home with sunlight.
