The reason that solar panels is so popular today is that the sun is an endless source of energy that we can rely upon. This energy supply is really limitless and will continue on for many lifetimes. Low cost energy can definitely originate from solar panels, especially if you can work with companies that offer rebates and rewards prior to installation. Exactly how do solar panels generate electricity? The following will reveal this mystery to you.
Most people worry about the initially high cost of the solar panels, which is the number one reason for not making the switch. However, the good news is that it probably isn't as expensive as you think, and you can actually build your own solar panels at home with some basic tools and parts that are all available via the internet. It may surprise you to find that many of the products you already have in your home can be used to create a simple solar panel design, for instance, you probably own a saw, drill, screwdriver and a wooden container of some sort. Don't overlook the likelihood of needing wood glue or other adhesives such as silicone caulk available to aide in box assembly and solar panel attachment.
Your simple box with a plexiglass front will allow sunlight in but will ensure the protection of the cells. You will glue your solar cells to the substrate, which are the strips of wood that you glue to the inside of your box. Just a dot of silicone caulk in the center of the cell will keep the cells steady when the wood expands or shrinks. To avoid damaging your solar cell consider using a single dot of silicone caulk to keep the wood free of encumbrances. Once the caulk has set, all you need to do is to drill a hole in the box for the wires but make sure to fill it with caulk after you have pushed the wires through to make sure that no moisture gets in. The plexiglass will have to be screwed on and mounted where you want it.
Solder on your diode before you attach it to batteries. This way, power will only be able to flow from the solar cells to the batteries and not the other way around. Having your batteries power your solar panels is a waste of energy. This step may not be necessary if you choose to use a charge controller. Although it does require a small amount of do it yourself know how, building your own solar panel really isn't that hard after all. It's really no harder than knowing what materials you'll need, obtaining them before you begin and having the patience to complete the task.
