Photovoltaic self-consumption

With the evolution of technology, it has been possible to develop multiple methods to supply homes, businesses and companies with electricity independently. One of the most popular, efficient and easy to apply methods is photovoltaic The conjugation of the word self-consumption refers to the actions of producing and consuming something specific. While the word photovoltaic refers only to solar panels. In other words, photovoltaic self-consumption is the creation and consumption of electrical energy produced from solar energy.

This is a method to generate electric energy in an easy way, due to the fact that electric energy can be produced independently and without polluting the environment (an aspect that makes it so popular nowadays).

This supply method can be used in different occasions, either in homes, companies, institutions, among others.

Classifications of the types of solar photovoltaic systems

It should be noted that photovoltaic self-consumption can be classified or distributed in different ways, because there are several ways to use this system to obtain electricity.

Among the most commonly used systems are the following:

Switched systems

This refers to the fact of using switches integrated in the solar energy system, with which the direction of the electricity can be alternated without any complication. With this, an ordinary house can be converted into a power distributor without any problem. However, to complete this system it is extremely necessary to have stationary batteries to relate to the energy storage.

Isolated systems

This can be selected as one of the best systems available, because the excess solar energy generated can be supplied to the main company that provides the service or the management of the solar panels.

In this way, secondary electricity services can be paid for through electric charges. However, to be able to install this system or use it, it is necessary to have more expensive equipment at home and to know the trade laws of each country, since it is not available to make this exchange in all nations.

Connected systems

This is considered the most basic of all, because only the basic equipment is used for the production of solar energy. It works only during the day and the excess energy can be stored in an electric battery for later use, either at night or during a rainy day.

How does the photovoltaic self-consumption system work?

he operation of this system is quite simple, even its name mentions it, it is a system of electricity generation through solar energy, which works to save money and contribute to the environment (as it is a totally renewable energy and zero pollutant).

This works thanks to one large solar panels that are implemented on top of the house, company or enterprise, which have the function of storing all the energy received by the sun, and then send it through cables and other equipment to a battery, where it is stored for use during the night.

The equipment used are mainly known as: solar panels and inverters, although in some occasions, switches can also be used to make a different circuit.

Knowing this, it is essential to know what each of the aforementioned devices is used for:

The inverter is an object that is responsible for making the transformation of solar energy, in alternating current (this is the current currently used by appliances to operate).

While the solar panels or solar panels are only responsible for receiving the solar energy emitted by the sun. To then send it through a system that has as continuous energy.

Finally, in some occasions it is also possible to implement electric batteries to the system, in order to have electricity during the night.

Advantages and disadvantages of photovoltaic self-consumption

Owning a photovoltaic self-consumption system can be very useful, however, paying for this equipment can be somewhat complicated, due to the cost, installation, transportation, among others. However, it is an electricity system that is worthwhile in many aspects, since it provides the following advantages:

- One of the main benefits of the photovoltaic self-consumption system is the fact of having unlimited electrical energy during the day and a reserve that can vary in its time of use, depending on the capacity of the electric battery.

- You can choose to sell the surplus energy or make a change with an electricity company to reduce a debt.

- Modern equipment is used in most cases, with a life span of up to 30 years, i.e., no payments to private companies for electricity services during that time.

- Contracts with electricity companies are avoided, since the company generates its own energy.

- Dependence on the country, company or electric service providers is reduced.

- You can use electricity all day long without fear of a high bill coming home.

- All power outages can be avoided.

- It is a way to generate clean, free and inexhaustible energy.

One of the obstacles that stood in the way of a person being able to acquire this service was the price of the equipment, because they were very modern for the time, therefore, they had a price that was unaffordable for many people. However, with the passage of time the price of these objects was decreasing, due to a series of events that were occurring.

On the other hand, one of the main disadvantages of photovoltaic systems is the fact that there will be no energy production at night, rainy days, among others. That is why in order to avoid lack of electricity, an electric battery must be acquired to store energy during the day, and thus have it available at night.
