Solar panels are used to produce renewable energy from the sun, and are a clean and environmentally sound means of collecting energy. Solar energy is becoming a more popular source of energy as people start to worry about energy costs and the environment. Homeowners can reduce their investment by learning how to make solar panels themselves.
Solar panels produce energy by emitting photons. Solar cells are placed in solar panels in a grid pattern to produce energy. Negative and positive charges are produced by millions of atoms. Silicon and different atoms are used to produce the charged stimuli. There are three types of silicon: monocrystalline, polycrystalline, and amorphous silicon which are all used in panels. Silicon does not produce energy until it comes in contact with the photon particles produced by the sun. When this happens it produces energy. The voltage and current in the solar cell determines the capacity or amount of power the cell produces.
The flat plate collector and the concentrating collector are the two types of solar panels. The flat plate collectors are flat, and are primarily used in residential environments. These collectors are typically seen on top of residential rooftops. They have a transparent glass cover that protects the solar cells from damage and aids in reflection of sunlight onto the cells. The primary use of flat plate collectors are to heat water, space heating, and lighting in residential homes. Flat plate collectors are what can be made for a fraction of the cost at home, and we will teach you how to make solar panels. Concentrating collectors are capable of producing larger quantities of electricity as compared to flat plate collectors. The energy produced by these panels are used in both commercial and industrial applications such as air conditioning, central power generation, and heating. Concentrating collector panels have curved mirrors with a front or back covering of silver or aluminum or some type of reflective material. Concentrating collectors can generate power more efficiently and economically than flat plate collectors. The downside is that they are more expensive, and usually require more maintenance.
The biggest problem with solar panels is how little electricity they produce compared to the size of the actual panel. A single solar cell provides enough energy to power a calculator, but if you want to power a house you’ll need several hundred or thousand cells, depending on your needs. New technology being developed is helping to improve the efficiency of solar energy systems.
The future of solar panels and solar energy are very bright. Great improvements are needed before it become the leader of supplying energy. Solar panels are used to provide only a small portion of energy worldwide. As technology grows the use of solar power is destined to compete and grow to hopefully outweigh tradition power sources to where we will have a cleaner environment and protect our planet. Once people discover that you don’t have to buy retail panels, it’ll motivate them to make solar panels at home.
