Solar energy is energy provided by the sun. This renewable energy source converts radiant energy from the sun into electricity. In order to take advantage of solar energy, home owners will hire contractors who specialize in this field. Solar power contractors will install panels onto a home. The panels are made up of numerous solar cells. These cells will convert the sunlight into electricity.
Cell - A cell is a single unit that is capable of converting chemical energy into electrical power. A battery is made up of several cells connected together to produce high voltage levels.
Peak Sun Hours - The peak sun hours are the number of hours per day where the solar irradiance reaches one thousand watts per square meter.
Photoelectric Cell - A photoelectric cell is a device that is designed to measure light intensity. This device converts light to electricity and then measures it.
Photoelectrochemical Cell — A photoelectrochemical cell is a device where the electricity in the cell produces a chemical, like hydrogen, which is then withdrawn and used.
Photovoltaic - Photovoltaic is the direct conversion of light to create electricity. The process involves special panels that collect the lights energy to be converted.
Hybrid System - A hybrid system is a photovoltaic system that combines other sources of electricity generation. For example, solar panels will work together with wind turbines and generators. In addition to solar, wind is also a renewable resource.
Battery Life — Battery life is the period of time a cell will operate at a high level before it needs to be replaced or charged.
Solar energy is becoming an increasingly popular source of alternative electricity, as apposed to other energy sources like oil that are limited and cause pollution. However, with the rise in the popularity of solar energy, there is rise in the need for solar energy contractors. Such contractors are contacted when a home or business owner wishes to convert their home and use renewable energy rather than traditional forms. When you contact the contractor, look into the equipment that you will need to install in your home, as this can be a costly endeavor. Find out all you can about photovoltaic panels and cells that you must install on the roof of your building. If you do not live in a sunny area, you might not get that much power by only running a renewable energy source. Inquire about perhaps running a dual power system, where you have the solar modules installed, but also have a back up heating and cooling system that is not run on natural electricity. It is important to talk to a few different contractors to fully understand the service that you are committing to. Find one that can accurately judge the amount of sunlight your panels can pick up for green energy, and will tell you all about using an inverter. Also, check the warranty for both your equipment and contractor, as basic maintenance and repair can be costly. While it is important to help the environment, you will want to find a company that will help you do it at the most affordable rate possible.
