What is a Solar Panel? - The Answer Could Save You Money!
What is a solar panel and what does it do? The word solar panel is often used colloquially for either a solar photovoltaic module or a concentrating solar power system. Although the term refers to both types of solar energy generation equipment, the latter is more common in the United States and in many other parts of the world. A solar power system is a set of solar collectors, which are connected to create an output of electricity. In the case of what is commonly known as a solar photovoltaic system, this is a set of photovoltaic (PV) cells connected to create an electrical output.
What is a solar inverter? The inverter changes an AC voltage (in Ampere or Hertz) from direct current (DC) to alternating current electricity. An inverter can be used to convert DC to alternating current electricity at a lower cost than it could be done by connecting panels together. AC electricity can be cheaper if it comes from one unit that uses a low initial starting voltage and has fewer number of units.
How do solar panels work? A conventional solar power system consists of a collection of photovoltaic cells connected together. This collection of cells convert light energy directly into electricity or, to be more specific, direct current electricity. A portion of the cells is covered with a thin layer of silicon, which is called the photovoltaic cell. This thin silicon layer is key to converting energy because the amount of light energy needed to produce a pulse of electricity is generally rather short.
What is a solar panel made of? Solar panels are typically made from either glass or plastic. Glass panels, which are usually clear, are made from materials that do not heat up very much and which are less expensive. Plastic panels, also called roll-to-roll or roof-mounted panels, are made of a flexible material such as nylon or thermoplastic.
How are solar panels connected to your home? Solar panels need to be placed on a structure that has direct access to a utility line. The connection between the panel and the utility meter should be designed in such a way that the energy produced does not escape or be lost. You might want to have the panel installed so that you have an inexpensive meter that you simply add to the pole and meter the energy that is generated.
Are solar panels "green" and environmentally friendly? Yes, in a few ways. They do not release greenhouse gases into the atmosphere and they use a portion of the electricity that they produce to power the inverters that turn the DC current back into the alternating current (AC) that your home uses. However, there are some pollutants that are emitted when you use a solar panel, especially during the manufacturing process. These emissions include certain gaseous emissions, such as carbon dioxide, sulfates, nitrates, methane, radon, and water vapor.
How do I finance my solar energy panel? Most banks will not give you a loan for a solar energy panel. In some cases, your bank may be willing to work with you by making you an "Installment Agreement". This type of arrangement allows your bank to purchase the needed equipment during the time that you pay off the loan, in exchange for fees for the installation.
What is a solar energy panel? Solar panels are a great way to save money on your electric bill. In addition to paying for the panel itself, you also need to pay for the connections to the utility company, the materials to make the panel, and the inverters that turn the DC energy into AC electricity. If you plan to build your own panel, then this information will be invaluable to you.
