Types of Solar Panels – Solar Energy Panels As Renewable Energy

Solar panels are used to convert sunlight into electricity. This electrical energy can be used for running household appliances and lights at night. Photovoltaic cells in solar panels absorb sunlight and change it into energy usable by the appliance. The word solar panel comes from the term solar.

Many States have laws that allow the home owner to sell surplus electricity back to the power grid. The home owner may receive a credit on their bill from the power utility for the amount of electricity that they sell back. The amount of credit that you receive will vary by state and may be capped at a certain amount http://solarkhanhhoa.com/dien-nang-luong-mat-troi-tai-nha-trang/. The use of solar panels has eliminated the need for utility companies to make any money off of your excess electricity.

Many States have programs that allow a percentage of your electricity purchased and sold back to the power grid, also called net metering. Net metering allows the home owner to generate an extra profit from their solar panels by using less electricity than they consume. Many States have policies that cap or eliminate the ability of a homeowner to receive a net metering refund.

There are four types of solar panels. They include the photovoltaic cell, the concentrating solar energy system, the stand-alone solar energy system, and the hybrid or full solar energy system. Photovoltaic cells convert light energy into electricity by taking the electrons in the cells and putting them in the proper polarity. The positive side of a photovoltaic cell is that it has the ability to generate electricity. The negative side is that it has a limited ability to generate energy and it needs direct sunlight so it can absorb photons.

The concentrating solar energy system takes advantage of the inherent photovoltaic effect. This is made possible by the use of a vacuum. The vacuum increases the number of photons that are absorbed and this in turn generates electricity. The stand-alone system is also known as the PV system because it doesn’t utilize a vacuum. It uses one or more concentrating technologies and this is the most efficient method of creating renewable energy from the sun.

The hybrid solar panels combine the benefits of both the stand-alone and the photovoltaic systems. Cells are placed on the surface of the roof. When daytime light shines on the cells, photons are absorbed and converted into electricity. The hybrids have PV cells that utilize the same methodology of the stand-alone cells but with added advantages of being able to harvest more photons from the sun’s rays.
