What are solar panels, and how do they work？
Solar panels, also known as photovoltaic (PV) cells, are an essential component of a solar panel system. They play a crucial role in converting sunlight into usable electricity. Understanding how solar panels work is fundamental to harnessing the power of solar energy efficiently.
Photovoltaic cells are the heart of solar panels. These cells consist of semiconductor materials like silicon that can convert sunlight directly into electrical energy. When sunlight strikes the surface of a solar cell, it excites the electrons within the material, causing them to flow and create an electric current.
To make practical use of this direct current (DC) electricity produced by solar cells, an inverter comes into play. The inverter’s primary function is to convert DC electricity into alternating current (AC), which is suitable for powering homes or businesses. AC electricity is what we commonly use for our everyday appliances and electronics.
Solar panels themselves are composed of multiple interconnected solar cells arranged in a specific pattern to maximize their efficiency. These interconnected cells form modules that collectively make up a complete solar panel system.
The process starts with sunlight hitting these interconnected PV cells on the surface of the solar panel. As photons from sunlight strike the surface, they transfer their energy to electrons within the semiconductor material, freeing them from their atoms and generating an electric charge.
These freed electrons then move through an electric field created within the PV cell by its internal structure. This movement creates a flow of electrons or electric current that can be harnessed for various applications.
It’s important to note that not all light sources can generate sufficient energy for effective electricity production. Solar panels primarily rely on direct sunlight for optimal performance; however, they can still generate some power even on cloudy days when diffuse sunlight is available.
While solar panels excel at capturing energy from direct sunlight, advancements have been made in technology to improve their performance under less ideal conditions. Some solar panels are designed to be more efficient in low-light situations, making them suitable for cloudy or overcast days.
Solar panel systems can be complemented with energy storage solutions such as batteries. These batteries store excess electricity generated during sunny periods and make it available for use during cloudy days or at night when sunlight is not available.
What are solar panels, and how do they work？
Yes, solar panels can still produce electricity on cloudy days, although at a reduced efficiency compared to sunny days. Even though clouds may obstruct direct sunlight, solar panels are designed to harness diffused sunlight as well.
