A pyranometer is a device used to measure solar irradiance. It is a solar energy meter and tells us how much sunlight is reaching a specific area. It measures the amount of solar energy in watts per square meter. These devices are used in solar systems to assess their performance and installation quality. Originally, they were primarily used in climate and weather research. However, with the increasing global interest in solar energy, these devices have gained significant popularity.
Pyranometers consist of a dome, a black absorber, a thermopile for temperature measurement, and sometimes additional electronic components. The dome acts as a filter device, allowing particular solar wavelengths to pass through. In simpler terms, a pyranometer measures how much sunlight is shining on a certain area and works based on the Seebeck effect or thermoelectric effect.
What is Pyranometer Used for?
Solar energy serves as the primary source of extraterrestrial energy for the Earth’s surface. This has significant implications in two key areas – weather and climate, as well as the generation of power through solar harvesting. Solar radiation greatly affects weather patterns, making it significant in weather and climate studies. So, pyranometers are commonly used in these studies to measure Global Horizontal Irradiance (GHI). It calculates how much solar energy reaches the Earth’s surface.
Pyranometers has also several applications in the solar energy industry, to track the performance of solar power plants, especially those using PV technology. It helps to determine the efficiency and analyze the expected output based on pyranometer readings. If the efficiency of the power plant drops, it is an indication of the need for maintenance.
Additionally, pyranometers find uses in building automation and agriculture for various purposes related to measuring solar radiation.
To sum up, solar energy plays a vital role in weather or climatic research work and solar energy production, where pyranometers are used to measure solar irradiance and monitor the performance of solar installations.
