Table of Contents

Greetings from AUSEUSA, we welcome you to the realm where using sunlight for the generation of power has become important for creating an eco-friendly environment. As technology is progressing rapidly, the method for the generation of electricity has also changed. In today’s era, we can obtain energy from various sources. Now, you can get electricity without using fossil fuels.

All thanks to technology. You can utilize free resources; like sunlight, for the generation of electricity. Solar panels along with PV cells play an important role in the generation of energy. This article is mainly focused on Photovoltaic Systems or simply PV systems. Without any further delay, let’s begin with our topic:

What is the Photovoltaic System?

Photovoltaic System, solar photovoltaic system, solar power system, or PV System are terms that are used interchangeably to mention the electric power system that can convert sunlight into electricity. In recent years, they have expanded quickly because they fall in the category of promising renewable technology.

Photovoltaic cells are used in PV Systems that are helpful in the generation of  DC (DC stands for direct current). After technology gained progress after the 1950s, solar voltaic cells came into being particularly by researchers in the USA. Semiconducting materials such as silicon including mono and polycrystalline are commonly used in the construction of solar cells. Required current and voltage can be achieved by connecting the cells parallel or in series.

Among monocrystalline and polycrystalline photovoltaic cells, monocrystalline are most widely used. Because they offer a good combination of cost and efficiency. Polycrystalline PV cells are the second option because they are more ineffectual. Besides mono and polo, emitter-wrap-through is also used in PV cells. Tiny laser-drilled holes are used in emitter-wrap-through to enhance the overall efficiency of cells.

The cells made up of silicon give rise to the formation of the crystal lattice. When atoms of silicon are connected, they give rise to a crystal lattice (the unit that produces electricity from sunlight). Various types of technologies are employed in the manufacturing of PV Systems. Among them are thin-film, nanotechnology, crystalline silicon, etc.

Parts of PV System:

A PV System includes the following parts:

1.Solar panel:

Solar panels are also known as solar modules. The solar cells are packed in a frame made up of metal. Solar cells in this form are known as solar panels or solar modules. It serves as a receptacle for sunlight and plays an important role in the generation of electricity. It is not wrong to say that they are considered the backbone of any PV System. The photons that strike with cells are converted into electrical power.

2.Solar inverter:

The main function of a solar inverter is to convert DC (DC stands for Direct Current) into AC (AC stands for Alternating Current). They are important because the power used in commercial and residential places is in the form of alternating current.

3.Racking and mounting system:

Such a system is efficient in providing stability and enough support to the solar panels. By installing a racking and mounting system, you can ensure that the solar panels are fixedly attached to the outbuildings, rooftops, etc.

4.Charge manager:

A unique device known as a “ Charge Manager” is often employed in PV systems (mainly for off-grid systems) for effective management of the charge flow between the panels and rechargeable batteries. A charge controller plays a vital role in the optimization of battery performance as well as in avoiding overcharging it.

5.Spare battery:

This is an optional component. And is often used for off-grid systems. As long as the shine is shining and photons are hitting the solar panels, you can get free electricity. The function of a spare battery is to store extra electricity for later use when there is not enough sunlight or at night.

6.Monitoring system:

As the name suggests, a monitoring system can monitor data, performance, efficiency, and production, as well as potential issues associated with the PV System.

Other important components that play an important role in PV Systems include wiring and connectors, a combiner box, a disconnect switch, and a power meter (used for grid-tied systems).

How does the PV System work?

The working of PV Systems is highly sophisticated. Read on to learn how this advanced green energy solution works:

1.Solar panels are installed at places where there is enough sunlight.

2.Within solar panels, there are tiny cells known as PV cells or solar cells. When solar radiation falls on them, it excites the material that is present in the solar cells (mainly semiconductors) leading to the generation of electrical current. The greater the incident light, the more will be the flow of electricity.

3.As the electrons within the cells become excited, it leads to the generation of direct current.

4.As DC cannot be utilized in our homes, it is converted into alternating current via solar inverters.

5.For grid-tied systems, the electricity can be fed back, if more energy is produced.

6.The current after passing through the inverter reaches the batteries. Where it can be stored for later use. This is possible in an off-grid system. Where there is no coupling to the grid.

How many types of PV Systems are there?

There are three types of PV Systems including the following:

1.Off-grid System
2.Grid-tied System
3.Hybrid System

Off-grid System:

An off-grid system works independently irrespective of the utility grid. Batteries are an important part of the off-grid system for storing extra electrical charges for later use including when there is not enough sunlight. The main advantage of getting an off-grid system is that you are capable of providing electricity to remote locations. The users are completely dependent on free resources and get the benefit of not paying electricity bills.

Grid-tied system:

Such systems are grid-dependent. The electricity that is generated in excess quantities falls back into the grid. Grid-tied aka on-grid systems are most widely used in homes. If you want to reduce your electricity bills and want to minimize your carbon footprint, then without any doubt, this type of system is best for you. Also, you do not need a battery storage system with a grid-tied system. Micro or solar inverters help establish a secure connection to the national grid.

Hybrid voltaic system:

If you want to contribute to your environment by creating a green energy solution, then a hybrid voltaic system is the best option. A hybrid system combines the technology of solar batteries with solar panels. The excess electricity produced by solar panels during the daytime can be stored in batteries for later use. They are highly flexible and their demand is increasing day by day.

Why choose a PV System?

In today’s rapidly developing society, more and more electrical appliances and electrified equipment are used in people’s work, life, and production, which puts forward more requirements for obtaining energy. At the same time, there are more and more ways to obtain energy, among which solar photovoltaics can be called the most flexible and easiest way.

For different application scenarios, solar PV Systems provide a lot of convenience and benefits. Read on to know, what these are:

In developed markets, solar PV Systems provide the following values for people’s lives and work.

1.Lower electricity costs, especially for factories and large commercial entities with large power consumption, the investment return period of solar PV Systems is generally 3-5 years, and the PV System life cycle is zero cost in the subsequent 15 years.

2.It ensures a safe power supply. When the power grid suddenly loses power, the PV System can still rely on its independent power generation capacity to provide a safe, stable, and continuous power guarantee for production and life.

3.The role of heat insulation and cooling. When PV Systems are installed on factories and roofs, photovoltaic panels can directly absorb strong sunlight and isolate the scorching temperature, lowering indoor temperatures and reducing air conditioning power consumption.

In developing markets, solar PV Systems not only provide the above benefits but also provide additional uses:

1.In many countries in the world, some areas are not covered by the power grid, or the power grid is severely aging, resulting in frequent power outages. Solar PV Systems provide people in these areas with an energy supply method that is not dependent on the power grid.

2.Doubtlessly, it is a clean and quiet energy method. Compared with traditional diesel engine power generation and coal heat generation, solar PV Systems provide people with clean energy without exhaust gas pollution and eliminate the rumbling noise of traditional diesel engines;

3.If the solar PV System is installed on a vehicle, then this compact solar PV System adds mobility and provides a flexible energy supply for dispersed energy demand points.

A PV System entertains its users with numerous benefits. That is why their demand is increasing rapidly among people and businesses.

Applications of the PV System:

Due to their numerous benefits, PV Systems are used in various places including the following:

1.Residential and commercial places
2.Utility-scale farms
3.Remote areas
4.Streets
5.Powering of water pumps
6.Can power solar desalination processes
