What is a Pyranometer and How is it Used to Measure Solar Radiation?

A pyranometer is a scientific instrument designed to measure solar radiation flux density from a hemispherical field of view. It plays a critical role in meteorology, climatology, solar energy systems, and agricultural research by providing accurate data on sunlight intensity.

How a Pyranometer Works

Most pyranometers use a thermopile sensor that generates a voltage proportional to the solar irradiance. This data helps in monitoring and optimizing solar panel efficiency, weather forecasting, and environmental studies.

Key Applications and Benefits

Common uses include photovoltaic system monitoring, meteorological stations, and agricultural management. By understanding solar input, industries can enhance energy efficiency and sustainability.
