Glass in building — Laminated solar photovoltaic glass for use in buildings — Light transmittance measurement method

This document specifies a test method of light transmittance for the laminated solar photovoltaic glass for use in building. This document is applicable to flat modules with light transmittance in the visible range (wavelengths from 380 nm to 780 nm). This document does not cover the assessment method of total solar energy transmittance of the flat module.
