Solar panels, also known as photovoltaic panels, are devices that harness the power of sunlight to generate electricity. They play a crucial role in the field of engineering, particularly in renewable energy systems. The world needs a solution, or a temporary fix to combat the climate change problems and so, understanding the fundamentals of solar panels is important for engineers. In this article, we will explore the basics of solar panels, how they work, and their significance in the field of engineering. Solar panels are made from multiple photovoltaic cells, which are made from silicon. When sunlight, or photons, appear on the surface of the solar panel, the photovoltaic cells absorb the energy from the photons, causing electrons to be released from their atoms. These free electrons flow through an electrical circuit within the solar panel, generating direct current (“DC”) electricity.
This DC electricity can then be converted into alternating current (“AC”) electricity using an inverter, which is the type of electricity used in buildings. Solar panels have numerous applications in engineering. They are commonly used in solar power systems for different types of buildings, as well as in large-scale solar farms to generate electricity. Solar panels can also be integrated into various engineering projects, such as solar-powered vehicles and portable charging stations. One key area of engineering where solar panels play a critical role is in off-grid and remote power systems. In remote locations where access to electricity is limited, solar panels can offer a permanent source of power. Engineers that work in this field often design and build solar power solutions in remote areas, helping to improve access to electricity and make the quality of life better for communities in such locations. Solar panels also have important environmental benefits.
Solar power is clean and renewable, producing no harmful effects on the climate. Solar panels can significantly reduce greenhouse gas emissions, air pollution, and dependence on fossil fuels. In conclusion, solar panels are essential devices that generate electricity from sunlight, and are an important section in the field making it an interesting option for students that intend to study engineering. Engineers specializing in renewable energy systems play a critical role in designing, implementing, and improving solar power solutions, contributing to a more sustainable future.
