What Are Solar Panels?
Solar panels are an essential component of a solar energy system, responsible for harnessing sunlight and converting it into electricity. They are commonly used in both residential and commercial installations.
These panels work by absorbing sunlight through photovoltaic cells, which generate a flow of electrons and create an electric current. There are different types of solar panels, including monocrystalline, polycrystalline, and thin-film panels, each with its own set of advantages and efficiencies. The overall goal of solar panels is to reduce dependence on non-renewable energy sources and decrease carbon emissions, contributing to a more sustainable future.
How Do Solar Panels Work?
Solar panels work by absorbing sunlight through photovoltaic cells, which then generate direct current (DC) electricity. This electricity is converted into alternating current (AC) by an inverter for use in homes and businesses.
Photovoltaic cells, also known as solar cells, are typically made of semiconductor materials that release electrons when exposed to sunlight. These free electrons create an electric current, which is then collected and channeled through conductive materials within the solar panel. The inverter is a crucial component that transforms the DC electricity produced by the solar panels into AC electricity, which is the standard form of electricity used in households and commercial buildings.
The efficiency of solar energy systems depends on various factors such as the angle of sunlight, weather conditions, and the quality of the solar panels and inverters.
