What is a Pyranometer and What is it Used to Measure?

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.

How a Pyranometer Works

Using a thermopile sensor, the device detects both direct and diffuse solar radiation. The sensor generates a voltage proportional to the solar irradiance, providing accurate and reliable data.

Key Applications

Meteorological stations, solar panel efficiency testing, and environmental monitoring all rely on pyranometers. Specifically, pyranometer is used to measure global horizontal irradiance (GHI), essential for optimizing renewable energy systems.

Frequently Asked Questions

What units does a pyranometer use?

Measurements are typically in watts per square meter (W/m²).

Can it work on cloudy days?

Yes, it measures diffuse radiation even under overcast conditions.
