The Basics of Solar Panels
Solar panels are devices that convert sunlight into electricity through the use of photovoltaic cells. These cells, made from semiconductor materials, create an electric field when exposed to sunlight. As photons from the sunlight strike the surface of the solar panel, they transfer their energy to the electrons in the cells, allowing them to flow and generate an electric current. This direct current (DC) is then converted into alternating current (AC) using an inverter, making it suitable for powering homes, businesses, and even entire communities.
How Solar Panels Work
Solar panels rely on the photovoltaic effect to convert sunlight into electricity. The photovoltaic cells in solar panels are typically made of silicon, which is a semiconductor material. When sunlight hits the surface of the solar panel, it excites the electrons in the silicon atoms, causing them to move and generate an electric current. The generated current is then harnessed and utilized for various applications.
