How Do Solar Panels Work?

Why Use Solar Panels?

Solar energy begins with the sun. Solar panels, also known as photovoltaics, are used to convert light from the sun, which is composed of particles of energy called "photons", into electricity that can be used to power elecrical loads. Light from the sun is a renewable energy resource which provides clean energy, produced by solar panels.

Solar panels can be used for a wide variety of applications including remote power systems for cabins, telecommunications equipment, remote sensing, and of course for the production of electricity by residential and commercial solar panel systems.

On this page, we will discuss the history, technology, and benefits of solar panels. We will learn how solar panels work, how solar panels are made, and how solar panels create electricity.

How Do Solar Panels Work?

Solar panels collect clean renewable energy in the form of sunlight and convert that light into electricity which can then be used to provide power for electrical loads. Solar panels are comprised of several individual solar cells which are themselves composed of layers of silicon, phosphorous (which provides the negative charge), and boron (which provides the positive charge). Solar panels absorb the photons and in doing so initiate an electric current. The resulting energy generated from photons striking the surface of the solar panel allows electrons to be knocked out of their atomic orbits and released into the electric field generated by the solar cells which then pull these free electrons into a directional current This entire process is known as the Photovoltaic Effect.

An average home has more than enough roof area for the necessary number of solar panels to produce enough solar electricity to supply all of its power needs. Assisted by an inverter, a device that converts the direct current (or DC current), generated by a solar panel into alternating current (or AC current), solar panel arrays can be sized to meet the most demanding electrical load requirements. The AC current can be used to power loads in your home or commercial building, your recreational vehicle or your boat , your remote cabin or home, and remote traffic controls, telecommunications equipment, oil and gas flow

Solar Panel Global Benefits

-Solar Panels do not contribute to global warming, as it does not contaminate the air by releasing carbon dioxide or other pollutants. The fossil fuels such as coal, oil, and natural gases that are being used for our electricity emit 10.3 million tons of sulfur dioxide, 3.9 million tons of nitrogen oxides, 2.4 billion tons of carbon dioxide, and over 50 tons of mercury a year. Not only is this dangerous for the environment but it's a danger to your health because these emissions are toxic. Every single year the emission of these gases rise considerably. Fossil fuel electricity generation is responsible for 36% of the country's emissions of carbon dioxide and the single largest contributor to global warming. (Statistics taken from the Official Energy Statistics from the US Government; http://www.eia.doe.gov/)

-Over its 35-year expected life, a 10 kW solar panel system will provide the equivalent CO2 reduction as planting 1450 trees. (Based on typical utility pollution) It will produce 575,000 kilowatt hours of electricity, as much as would be generated by burning 583,000 lbs of coal.

-Solar Panels are the most cleanest source of alternative Energy. There is absolutely zero pollution to the environment, which makes a better way of living for your children and generations beyond.
Solar Panel Personal Benefits
-It's free renewable energy unlike the source that is powering your current power supply. As long as the sun as around, you can take advantage of completely free energy.

-Slash your electricity and fuel bills by great numbers or get rid of them completely.

-According to a recent survey by California Solar Institute, for every $1 of savings from your energy bill annually, you get an increase of $20 in your home value. Hence, this means that a savings of $1500 or more will equate to an increase of $30,000 in your home sale value.

-A bill was just passed that provides people who purchase solar panels to take advantage of great tax credits, so when you buy solar panels, you automatically get a nice chunk of change taken off the cost right away.

-Once the initial cost of purchasing the panels are paid in full, the electricity it produces for the remainder of the system's lifespan, which is decades, is absolutely free!

-Solar panels make it possible to live off-grid, which means living in a self-sufficient manner without reliance on one or more public utilities. With the advent of global climate change, it has become more important that we do whatever we can to reduce the pressure on our atmosphere from the emission of greenhouse gases.

-For people who have their solar panels tied in with the utility company, the benefits begin from the moment the system comes online, potentially eliminating monthy electric bills or, and this is the best part, actually earning the system's owner additional income from the electric company. If you use less power than your solar electric system produces, that excess power can be sold, sometimes at a premium, to your electric utility company. So, let’s say you’ve got some solar power panels up on your roof for the summer but you decide to go on and take a vacation for a month. All the power that is being generated gets credited to your account. At the end of the year, if you use as much power as you feed back into the grid, your power bill is negligible.

-No more spoiling your food due to power outages

-The use of solar energy for homes and businesses can help reduce transport of fuel that would otherwise be used for heating, further reducing carbon emissions.

There are many other applications and benefits of using solar panels to generate your electricity needs - too many solar products to list here.
