ITI SOLAR TECHNICIAN PYRHELIOMETER

A pyrheliometer is a device that measures solar irradiance coming directly from the sun. The SI units of irradiance are watts per square metre (W/m⊃2;). Traditionally pyrheliometers were mainly used for climatological research and weather monitoring purposes, however recent worldwide interest in solar energy has also led to an increased interest in pyrheliometers. In this article we will explore the basic aspects of a pyrheliometer
