Solar Energy Is Becoming Increasingly Present in Today’s World, and Because of That, Several Questions Arise. Learn More About This Method of Electric Generation Below!
According to information from Uol, solar energy is recognized as a “clean” technology and a solution to mitigate the environmental impacts generated by traditional energy production methods, such as thermoelectric plants and hydroelectric plants. But how does the conversion of sunlight into electricity occur?
One of the most fascinating characteristics of solar energy is its ability to generate electricity not only on a large scale but also in a decentralized manner, directly in homes, through the installation of solar panels on rooftops. These panels are made up of several photovoltaic cells, which can be made from various types of materials, with the most common being Gallium Arsenide (GaAs), Polycrystalline Silicon, and Monocrystalline Silicon, in addition to thin films such as hydrogenated amorphous silicon (a-Si:H), copper indium selenide (CIS), and cadmium telluride (CdTe).

Viability and Challenges of Solar Energy: What You Need to Know
But how much energy does each panel generate? Each photovoltaic cell produces about 0.4 V, so to produce 12 V, sufficient to charge a battery, a panel with 30 to 40 cells would be required.
Is it possible to power a house solely with solar energy? It depends: a standard-sized solar panel has an average monthly production of 41.25 kWh/month, while the average consumption of a house is about 300 kWh/month, which would require the installation of several panels.
Solar energy is a viable and sustainable alternative for electricity generation, bringing environmental and economic benefits. With continuous technological advancements, its use is likely to expand, transforming the way we use and think about energy.
