Introduction

Energy is an integral part of human life, be it in form of electricity, biogas, or any other.  Though, initially we had enough natural resources to produce energy; but thanks to human greedy and negligent nature that we are at verge of losing our natural resource reserves. Then, in order to keep the things going and fulfill the energy needs, researchers discovered a new potential form of energy. The energy is generated with the help of solar panels by absorbing energy trapped in sun rays. Solar panels are a great way to absorb and use the sun's energy. It is a sustainable and environmentally-friendly method of harvesting energy. In this article, we will understand the functioning of solar panels in detail.

The Advantages of Installing Solar Panels

You can significantly cut down your expenses by installing a solar panel on your house. As a result, you won't have to be concerned about high energy expenditures. According to a study conducted by CEEW and BYPL, installing a solar panel can save you up to 95% of your monthly expenses. If you live in Washington, D.C., you must be experiencing a moderate amount of sunlight. Even with a solar panel, this moderate amount of sunlight per day can generate enough energy for a household of two adults and three children. However, you do not need to worry if you live in a cloudy place. The solar panels can draw energy from the sun even if the sky is cloudy.
Moreover, installing solar panels on your home increases the property's value. Therefore, solar panels on your house become a great point to advertise with your brokers. The insane tax credits and rebates that the government offers to anyone who has solar panels installed are a great benefit. When filing your taxes, you can claim up to 30% of the total cost of equipment and solar panel installation as a federal income tax credit. It is a great investment and can give you cheap electricity and save you from exorbitantly high bills. In addition, you can cut the cost of having a solar panel installed on your house by using the state and local rebates and the solar renewable energy credits. These credits are useful in earning more money. You can easily sell them to utility companies and enjoy a high return on this investment.

How to install a solar panel?

People hire professionals and contractors to install solar panel kits in their homes. The process is somewhat straightforward. Solar panels are generally installed on the roof. It is crucial to be safe and secure while working on the roof. Solar panels are made up of many photovoltaic panels. All the panels are linked with the various components commonly used to absorb the energy emitted by the sun. Installing a ring solar panel is quite popular due to its practical nature.

How do solar panels work?

The sun is a powerful source of energy. It is estimated that if we could utilise the sunlight falling on Earth’s surface for an hour and 30 minutes, the energy generated would be enough to fulfill the global energy needs for a year.  The sunlight that we receive is an electromagnetic wave that the sun emits. Due to the rotation of the earth around its axis and its yearly rotation around the sun, different parts of the world receive different amounts of sunlight at different times.

Types of solar panels

There are two basic types of solar panels: photovoltaics and concentrating solar-thermal power.

Photovoltaics

This is the more popular kind of solar panel. Photovoltaic cells are made by the careful layering of two semiconductors, usually made up of silicon. To create an electrical field, semiconductors are doped with other materials such as phosphorus and boron. The extra electron in phosphorus gives the cell a negative charge, and the electron-deficient boron adds a positive charge to the other part of the photovoltaic cell. This adds up to an electric field at the junction of the layers. The photovoltaic cells absorb the sun's energy after being exposed to sunlight. This generates an electrical charge.
The inner part of the solar panel is built in such a way that it leads to the movement of the electrical charge generated due to an electrical field present in the cell. There are conductive metal plates attached to the sides of the cell that collect the electrons and transfer them to wires to be used as well. The electrical energy produced by the sun results in DC. Numerous students want to learn about plants and alternative currents. Alternative current is used in most appliances required at home and school. There is a need to use inverters to convert the abundant DC into alternative current, or AC.

Concentrating solar-thermal power

This type of solar panel is typically used in large power plants to generate huge amount of energy using solar energy. In this system, mirrors or lenses are placed in such a manner to reflect and concentrate the sunlight into the receivers. These receivers generate electricity by converting solar energy into heat. This heat is used to produce electricity or stored for energy.
Scientists have come up with a very thin and flexible material to make solar cells. It reduces the size of the solar panels considerably. It is around 29 times lighter than paper. Because of these light solar cells, you can now integrate solar panels into the house's structure. There are also possibilities of wearing technology covered with this thin solar cell.

Conclusion

Solar panels are an essential addition to your home or business. These help us save and conserve the environment, but can also help us save money. The amazing tax benefits and returns are crucial points that make many people opt for solar energy. Professionals should do the solar energy installation. Installing solar panels in your home can completely help you be off the grid. All your electricity needs can be met with solar power if you get enough sunlight where you stay.
