What is a Pyranometer Used to Measure?

A pyranometer is a specialized sensor designed to measure solar irradiance—specifically, the amount of solar energy received per unit area. In simpler terms, a pyranometer is used to measure the power of sunlight in watts per square meter (W/m²). This data is critical for applications in meteorology, climatology, solar energy systems, and agricultural research.

Key Applications of Pyranometers

Pyranometers are essential in various fields. In solar energy, they help optimize the performance of photovoltaic panels by monitoring available sunlight. In agriculture, they assist in calculating evapotranspiration rates for irrigation planning. Environmental scientists use them to study climate patterns and global radiation budgets.

How Does a Pyranometer Work?

Most pyranometers operate using a thermopile sensor, which generates a voltage proportional to the temperature difference caused by incoming solar radiation. This voltage is then converted into irradiance values, providing accurate and real-time data.

Frequently Asked Questions
