WK92059 - New Classification for Reference Solar Spectral Irradiances: Direct Normal and Hemispherical on 37° Tilted Surface for Terrestrial Photovoltaic Applications

Work Item

ASTM WK92059

New Classification for Reference Solar Spectral Irradiances: Direct Normal and Hemispherical on 37° Tilted Surface for Terrestrial Photovoltaic Applications

1. Scope

These Standard reference solar spectral irradiance tables are adopted from G173-03 and solely used for terrestrial PV application.

Keywords

PV performance rating, Solar irradiance

Rationale

This new standard is created to solve the discontinuity issue of PV efficiency calculation. It will be used in PV testing labs, PV manufacturing companies, and solar farm developers, for performance measurements of PV products and PV researchers.
