Introduction

In recent years, the widespread use of photovoltaic modules in buildings has determined the types, structures, installation methods, and other aspects of photovoltaic modules that are integrated with buildings.

However, the large-scale installation of building photovoltaic panels has also caused many problems in terms of structural safety, electrical safety, and power generation efficiency throughout the life cycle.

In order to strengthen the structural and electrical safety management of building photovoltaic modules and achieve quality and efficiency improvement throughout the life cycle, scientific and reasonable The paper proposes that the structure, electrical and other working parameters of building photovoltaic modules meet the requirements of safe and reliable operation.

The scrapping determination conditions and test methods provide users or holders with a basis for determining whether building photovoltaic modules need to be scrapped, and promote the scrapping of unsatisfied photovoltaic modules.

Effectively determine the scrapping of building photovoltaic modules based on safety requirements and usage functions to ensure the safety of buildings and the commercial value of building photovoltaic modules.

This document is used to determine whether building photovoltaic modules are scrapped, but not to determine whether building photovoltaic modules are repairable.

The repair of building photovoltaic modules that meet the scrap determination conditions shall be decided by the holder.
