Question 1

What does a Typical Meteorological Year (TMY) dataset represent?

Accepted Answer

A synthetic year of hourly data representing average long-term conditions

Answer

A TMY is a composite dataset of 12 selected months from different years, chosen to statistically represent the long-term average solar and meteorological conditions at a location.

Question 2

Which irradiance component should be prioritized when designing a concentrating solar power (CSP) system?

Accepted Answer

Direct Normal Irradiance (DNI)

Answer

CSP systems use optical concentrators that can only focus direct beam radiation, so DNI is the critical resource parameter for CSP site selection and energy modeling.

Question 3

At what solar zenith angle does the Optical Air Mass (AM) equal approximately 2?

Accepted Answer

60°

Answer

Air Mass is approximated as 1/cos(zenith angle); at a zenith angle of 60°, cos(60°) = 0.5, so AM = 1/0.5 = 2.

Question 4

The Linke Turbidity Factor (TL) quantifies which atmospheric characteristic?

Accepted Answer

Atmospheric haziness due to aerosols, dust, and water vapor

Answer

The Linke Turbidity Factor describes the optical thickness of the atmosphere relative to a clean, dry atmosphere, accounting for aerosols, dust, and water vapor that attenuate solar radiation.

Question 5

Which of the following is a widely used commercial satellite-derived solar resource dataset for global projects?

Accepted Answer

Solargis

Answer

Solargis is a leading provider of satellite-derived solar radiation data and is widely used for bankable solar resource assessments globally.
