How Is Solar Radiation Measured? Sensors and Units
Solar radiation is measured with radiometers, especially pyranometers for hemispheric sunlight and pyrheliometers for direct sunlight. Instruments convert absorbed radiation into a calibrated electrical signal, reported as irradiance in watts per square metre (W/m²) or integrated irradiation in kilowatt-hours per square metre (kWh/m²).
