Tarcísio Simone, specialist in renewables, teaches a basic system that allows air conditioning to operate exclusively with solar energy, directly from the solar panel, without the need for batteries or connection to electrical grids, promoting sustainability and savings.

In the current energy scenario, a system is attracting the attention of consumers interested in sustainability and cost reduction: the possibility of operating air conditioning solely with energy from solar panels, eliminating the need for batteries or connection to electricity utilities. This solution is only effective during the day, ideal for offices or for those who work from home, but also economical, using solar energy.

One of the great highlights of this system is the use of an off-grid solar inverter without the need for a battery bank. This device allows the air conditioning, with an average consumption of 900 watts, to operate during the day taking full advantage of energy solar energy captured by the plates. The proposed scheme eliminates the use of energy from the electrical grid, enabling greener and more economical operation. Below, check out Tarcísio Simone's video and leave your opinion in the comments.

The air conditioning connection is made through a sensor connected to the inverter, which detects and uses energy directly from the solar panel. If solar production is insufficient, the system automatically compensates by pulling the minimum amount necessary from the grid, ensuring that the device continues to operate without interruptions.

First, you install the solar panels on the roof of your house. These plates are responsible for capturing sunlight and transforming it into electrical energy. The energy generated by the solar panels is sent to equipment called an inverter. The inverter has a special function: it adjusts solar energy so that it can be used by household appliances, including the air conditioner.

Typically, some solar power systems use batteries to store energy, but in this case, they are not necessary because in the example they would be directly connected. This simplifies the system and reduces costs. While the sun is shining, that is, during the day, the solar panels produce energy that is immediately used to operate the air conditioning. You can keep your home cool during the day without using mains power.

If at any time the energy produced by the plates is not sufficient, for example, on cloudy days, the inverter automatically seeks some energy from the electricity grid. This ensures that the air conditioning continues to operate without interruption. As most of the energy used comes from the sun, you save on your electricity bill. By using renewable energy, you help reduce pollution and contribute to a more sustainable planet.

This innovative method not only points to a growing trend in the adoption of renewable energy in homes, but also demonstrates how the technology can be applied to improve energy efficiency and reduce environmental impacts. As the efficiency of solar panels increases and associated costs reduce, this solution is expected to become increasingly affordable and popular among global consumers.

What do you need for the solar panel to power the air conditioning at night?

For a solar panel to power an air conditioner at night, it is necessary to implement a system that stores the energy generated during the day, as solar panels do not produce energy at night. Here are the key components to make this possible:

Solar panels: They capture sunlight and transform it into electrical energy. Depending on the size of your air conditioner, you will need more or fewer panels. The price varies a lot, but on average, each panel can cost between R$800 and R$1.200.

Converter: It is a device that transforms battery power into the type that your home appliances can use. A good inverter costs around R$2.000 to R$4.000.

Automatic transfer frame: Its function is to transfer the system's power supply to the concessionaire's network, when the cards cease to exist. The price is around 2000 reais.

Installation and Sizing: The cost of installation and having a professional correctly size the system can vary, but is generally around R$2.000 to R$5.000, depending on the complexity.

In summary, to set up a system that allows you to use your air conditioning at night with solar energy, you can expect to spend between R$12.000, considering all components and installation. It's important to consult an expert to assess your specific needs and ensure the system is right for your home.
