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 (W/m²) from a hemispherical field of view. It plays a critical role in meteorology, climatology, solar energy systems, and agricultural research.

Key Functions and Applications

Primarily, a pyranometer is used to measure global solar radiation—both direct and diffuse sunlight. This data helps in assessing solar panel efficiency, weather forecasting, and environmental monitoring.

Working Principle and Components

Most pyranometers use a thermopile sensor that generates a voltage proportional to the solar irradiance. The instrument is typically equipped with a glass dome to minimize thermal losses and protect the sensor.

Frequently Asked Questions

What units does a pyranometer use?

It measures irradiance in watts per square meter (W/m²).

How accurate are pyranometers?

High-quality models offer accuracy within ±1-2%, ideal for research and commercial use.
