What is a Solarimeter and How Does It Work?

A solarimeter is a scientific instrument designed to measure solar radiation. It is widely used in meteorology, agriculture, and renewable energy sectors to monitor sunlight intensity and duration.

Key Components and Operation

Typically, a solarimeter consists of a thermopile sensor that converts thermal energy from sunlight into an electrical signal. This data is then processed to quantify irradiance levels in watts per square meter (W/m²).

Applications and Benefits

From optimizing solar panel efficiency to agricultural planning, accurate solar radiation measurement helps in energy forecasting and environmental research.

Frequently Asked Questions
