- Scope
- This standard provides a set of standard spectral irradiance distributions for use in determining the relative performance of solar thermal, photovoltaic and other systems, components and materials under direct and hemispherical irradiance. Clarified that modeling the ground component at a constant albedo of 0.2 may introduce certain pitfalls. The table in this standard specifies the solar spectral irradiance of air quality 1.5, which is applicable to all solar energy utilization fields requiring standard spectral irradiance, and is suitable for normal direct radiation when the albedo is 0.2 (field angle is 5.8° ) and hemispherical radiation on a plane facing the equator and inclined at 37° from the horizontal, the data in these tables represent ideal clear-sky conditions.
