SSC Selection Post 2023 Graduation Level Question Paper (30 Jun, 2023) (Shift 1)
The correct answer is

Pyranometer

The correct answer is Pyranometer.

Pyrheliometers are used for DNI measurement, usually mounted on a solar tracker. Diffuse Horizontal Irradiance (DHI): This is the solar radiation on a horizontal surface coming from the sky (scattered radiation), excluding the direct radiation from the sun. DHI can be measured using a pyranometer with a shadow band or by subtracting DNI (converted to horizontal component) from GHI. The Pyranometer is a fundamental instrument in meteorology and solar energy studies for assessing available solar resources.
