Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for Standardization Work Part 1: Structure and Drafting Rules of Standardization Documents" Drafting.

1 Scope

This document gives the classification of photovoltaic glass modules for buildings, and specifies the environment and instrument requirements for light transmittance testing, samples, and basic light transmittance Rate test method, light transmittance test method and test report.

This document is applicable to the test of light transmittance of non-hollow flat photovoltaic glass modules for buildings with lighting requirements.

3 Terms and definitions

The following terms and definitions apply to this document.

4 Categories

According to the different light transmission modes of the components, the components can be divided into the following three categories.

a) Spacing type components Crystal silicon or thin-film batteries are connected to each other and encapsulated inside the glass, and there is a considerable distance between the batteries so that the components can transmit light The components are shown in Figure 1.
