Energy from the limitless resource of the sun is the primary focus of those that develop solar energy products. The sun is estimated by scientists last for billions of years, clearly showing this energy source is trustworthy. Several companies are now offering incentives that slash the costs of solar panels allowing most people to benefit from this cheap energy source. Exactly how do solar panels generate electricity? The following will reveal this mystery to you.

Solar cells are contained within boxes called solar panels. In some scientific way, electricity is created by the solar cells from sunlight. The creation of electricity using sunlight happens when the rays of the sun hit the silicone solar cells making electricity manifest. Although the energy comes freely from the sun, less than 1 V of electricity per cell is generated which means a lot of panels are needed to replace your energy needs. Solar panels can actually be made at home; many people make them in an attempt to reduce or eliminate their electrical bill. DIY experts will probably have no problem at all creating their very own solar panels at home as long as you have a soldering iron.

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. Glue is used to attach the cells to the box, and you will need to glue some wood strips inside the box. Only use a dot of caulk in the center of the cell because wood tends to expand and shrink with the weather. Using a single dot of caulk will allow the wood to shift without damaging your solar cells. 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. Then, screw your Plexiglas on and mount it where you want.

The items you need to build solar panels aren't hard to find if you prefer to do it yourself; you could order everything you need online or shop in local stores. When building solar panels, you have to start with solar cells that are powerful enough for your needs. You'll get more power from superior solar cells of course.

The usual ratio to keep in mind is that eighty solar cells will generate approximately one hundred watts of electricity. Based on how much energy you need, you can use this figure to estimate how many solar panels to build and how large they'll have to be.

There is no better time than now to switch to an alternative power source, considering the state of the global economy, especially since many experts fear that the worst is yet to come. If things do take a turn for the worst, having a renewable energy source that is free and allows you to be independent from the public grid might just prove invaluable.
