What is a solar panel?

Jul 13

The sun is the first source of solar energy. The solar panels, also known as PV (short for Photovoltaics) are often called "a title". PV panels (pronounced ">") are used for converting sunlight from the sun into electricity. This is done by using particles of energy called photons.

You can use solar panels for many purposes, including remote power systems for cabins and remote sensing. Also, you can produce electricity using residential or commercial solar electric systems.

This page will cover the history, technology, and benefits of solar panel technology. Learn how solar panels work and where to buy them.

A Brief History of Solar Panels

Solar energy has been around for more than 100 years. Solar energy was first used to produce steam, which could be used to power machinery. It wasn't until Edmond Becquerel discovered the "photovoltaic effects" that sunlight could be converted to electric power. Charles Fritts, who discovered the photovoltaic effect in 1893, created the first real solar cell. It was made by coating selenium sheets with thin layers of gold. From this humble start would come the solar panels.

Russel Ohl was an American inventor who worked for Bell Laboratories. He patented the first silicon solar cell. The same company produced the first solar panel in 1954 thanks to Ohl's invention. The first widespread use of solar panels was in space satellites. The 1970s was the era when most people's first exposure to solar panels was in their calculators.

Solar panels and complete solar panel systems can be used today to power many applications. Yes, calculators still use solar panels made of solar cells. They are used to supply solar power to whole homes and commercial buildings like Google's California headquarters.

How do solar panels work?

Solar panels capture sunlight as clean renewable energy and convert it into electricity that can be used to power electrical loads. Solar panels consist of individual solar cells that are composed of layers of silicon (which gives off the negative charge) and boron (+ which gives off the positive charge). Photons are absorbed by solar panels, which in turn create an electric current. Photons hitting the solar panel's surface generate energy that allows electrons to escape their atomic orbits. This energy is then released into an electric field by the solar cells, which pulls these electrons into a direct current. The Photovoltaic Effect is the name of this entire process. The average home has enough roof space to support enough solar panels to generate enough electricity to power all its needs.

A solar array can generate power during the day when it is connected to the grid. This energy is then used at night. Solar generator owners can get paid for excess power produced by their system through net metering programs. Off-grid solar applications require a Title="Two or greater batteries connected in parallel or in series. The battery bank is a device that prevents the batteries from charging too fast. A charge controller is also known as a ">charge controller" and, in most cases, an ">inverter. This device converts DC current into AC current. An inverter is also required. The charge controller sends direct current (DC), and electricity to the solar array. The battery bank then draws power to the inverter. This converts DC current into AC that can be used to run non-DC appliances. Solar panel arrays can be scaled to meet even the most stringent electrical load requirements with an inverter. AC current can power loads in homes and commercial buildings, boats and recreational vehicles, remote cabins, homes, remote traffic control, telecommunications equipment, and oil and gas flow monitoring.

Solar Panels: The Benefits

Solar panels are a practical and efficient way to generate electricity for many purposes.

Off-grid living is obvious. Living off-grid is when you live in an area that isn't connected to the main electric utility grid. Solar power systems are great for remote homes and cabins. It is no longer necessary to pay high fees for the installation of utility poles or cabling from the nearest main-grid access point. If properly maintained, a solar electric system can be less costly and provide power for up to three decades.

Apart from the fact that you can live off-grid with solar panels, the best thing about solar power is its renewable and clean energy source. It is becoming more urgent to do everything we can to lower the atmospheric pressure from the release of greenhouse gases. Solar panels don't have moving parts so they require very little maintenance. When properly maintained, solar panels are durable and can last for many decades.

The best part about solar panels and solar power? Once the initial costs of installation have been paid, all electricity produced for the rest of the system's life, which can be up to 15-20 years depending on how good the system is, is completely free. Grid-tie solar power system owners reap the benefits from the moment their system is online. This could eliminate monthly electric bills, or, perhaps, even earn them additional income from the electric companies.

Solar panels can be used to produce electricity in many other ways. There are too many benefits to mention. You'll learn a lot about the versatility and convenience of solar power by looking through our website.
