Solar energy is increasingly present in today's world and, because of this, several doubts arise. Learn more about this way of generating electricity below!
According to information from the Uol website, solar energy is recognized as a “clean” technology and a solution to mitigate the environmental impacts generated by solar methods. traditional energy production, such as thermoelectric and hydroelectric plants. But how does sunlight convert into electricity?
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 way, directly in homes, through the installation of solar panels on roofs. These panels are composed of several photovoltaic cells, which can be made from various types of materials, 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 and indium diselenide ( CIS) and cadmium telluride (CdTe).

Feasibility and challenges of solar energy: what you need to know
But how much energy does each card generate? Each voltaic cell produces about 0,4 V, so to produce 12 V, enough to charge a battery, a panel with 30 to 40 cells would be required.
Is it possible to power a house with solar energy alone? It depends: a standard-sized solar panel has an average monthly production of 41,25 kWh/month, while the average consumption of a home is around 300 kWh/month, which would require the installation of several panels.
Solar energy is a viable and sustainable alternative for generating electricity, bringing environmental and economic benefits. With continuous technological advances, its use tends to expand, transforming the way we use and think about energy.
