From photovoltaic cells to solar thermal systems, these technologies vary in their working principles and uses. In this blog, we will delve into the different types of solar energy technologies, exploring how they work and their various applications.
Photovoltaic (PV) solar energy stands out as one of the most prevalent and widely recognized solar technologies. It directly converts sunlight into electricity, providing a flexible and scalable solution for a variety of energy needs, from small personal devices to large-scale power generation.
Photovoltaic (PV) cells, commonly known as solar cells, are the heart of PV solar energy systems. These cells operate based on the photovoltaic effect, a process where sunlight is converted directly into electricity. When sunlight strikes the PV cells, it excites electrons within the cell''s semiconductor material, typically silicon. This excitation causes the electrons to move, creating an electric current. This current is then captured by electrical contacts on the cell and directed into an external circuit, where it can be used to power electrical devices or stored in batteries for later use. The efficiency and effectiveness of PV cells make them a crucial component in harnessing solar energy.
PV solar energy is incredibly versatile and is utilized in a wide range of applications:
