The Basics of Solar Panels
What is a Solar Panel
A solar panel is a device that converts sunlight into electricity. It is made up of multiple solar cells, which are typically made of silicon. These solar cells absorb photons from the sunlight, causing electrons to be set in motion and creating an electric current. The electricity produced by a solar panel can be used to power various electrical appliances and systems.
Types of Solar Panels
There are three main types of solar panels commonly used: monocrystalline, polycrystalline, and thin-film solar panels. Monocrystalline panels are made from a single crystal structure and are highly efficient. Polycrystalline panels are made from multiple crystal structures and are slightly less efficient but also more affordable. Thin-film solar panels are made using a thin layer of photovoltaic material and are flexible, making them suitable for certain applications.
How Solar Panels Work
Solar panels work by utilizing the photoelectric effect, where photons from sunlight knock electrons loose from atoms, generating a flow of electricity. When sunlight hits the solar panels, the photons are absorbed by the semiconductor material in the solar cells, creating an electric field. This electric field causes the electrons to flow in a specific direction, creating a direct current (DC). The DC electricity is then converted into alternating current (AC) through an inverter, which is used to power electrical devices or to be fed back into the grid.
