Ever wondered what solar energy is and how it works? Here is a simple introduction for you to understand the basics.
Solar energy is a type of renewable energy that is generated by capturing the energy from the sun's rays and converting it into electricity. It is a clean, sustainable and renewable source of energy that can help reduce dependence on non-renewable sources of energy like oil, natural gas, coal and nuclear energy.
Solar energy is produced through a process called photovoltaic (PV) conversion. PV cells are made of semiconductor materials such as silicon, and when they are exposed to sunlight, they generate an electric current. When many PV cells are connected, they form a solar panel.
When sunlight strikes the solar panel, the PV cells inside the panel absorb the energy from the sunlight and convert it into direct current (DC) electricity. This DC electricity is then sent to an inverter, which converts it into alternating current (AC) electricity, which can be used to power residential homes and commercial businesses.
The amount of energy that a solar panel can produce depends on several factors, including the amount of sunlight it receives, the size and efficiency of the solar panel as well as the angle and orientation of the panel.
Solar energy offers several advantages over traditional sources of energy, including:
