Solar Panels

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 electricrity 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 (RV/Marine Solar Panels), your remote cabin or home, and remote traffic controls, telecommunications equipment, oil and gas flow monitoring, RTU, SCADA, and much more.

Using solar panels is a very practical way to produce electricity for many applications. The obvious would have to be off-grid living. Living off-grid means living in a location that is not serviced by the main electric utility grid. Remote homes and cabins benefit nicely from solar power systems. No longer is it necessary to pay huge fees for the installation of electric utility poles and cabling from the nearest main grid access point. A solar electric system is potentially less expensive and can provide power for upwards of three decades if properly maintained.

Besides the fact that solar panels make it possible to live off-grid, perhaps the greatest benefit that you would enjoy from the use of solar power is that it is both a clean and a renewable source of energy. 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. Solar panels have no moving parts and require little maintenance. They are ruggedly built and last for decades when porperly maintained.

Last, but not least, of the benefits of solar panels and solar power is that, once a system has paid for its initial installation costs, the electricity it produces for the remainder of the system's lifespan, which could be as much as 15-20 years depending on the quality of the system, is absolutely free! For grid-tie solar power system owners, 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. How? 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!

There are many other applications and benefits of using solar panels to generate your electricity needs - too many to list here. But as you browse our website, you'll gain a good general knowledge of just how versatile and convenient solar power can be.

Solar Panels are typically installed on rooftops, building tops, or as stand-alone facilities. It is vital to install your solar panel so that it gets the most direct sun exposure - you want to make sure your solar panel is maximally effective year round.

Solar Panels perform at optimum capacity when placed in direct sunlight. Try to position your photovoltaic array directly under the noontime sun for maximum efficiency from your photovoltaic unit.

Remove all items unnessary items or trim branches that may be blocking sunlight to your solar panel. Trace the path of the sun in the sky to determine if an object is casting a shadow over your solar photovoltaic panels. If this is the case, then the operating efficiency of your unit will undoubtedly suffer.

Solar Panel Mounts are used to install photovoltaic solar panels. Solar panel mounts come in three main varieties: pole mounts, roof-ground mounts, and flush mounts. Using these mounts, you can install your solar panel onto an RV, on top of or against the side of a pole, on your roof, or even install them as a free-standing unit. You can learn more about installing solar panels using mounts in our mounts section.
