BS EN 62805-1:2017

What is BS EN 62805-1-Total haze measurement of photovoltaic (PV) glass about? 

The IEC 62805 series covers methods for measuring PV glass. The main objective of the IEC 62805 series is to equip entities in the field of solar energy engineering with best industry techniques to assess whether their PV glass products meet the required performance and quality benchmarks. 

BS EN 62805-1 is the first part of the series that specifies a method for measurement and calculation of the total haze and the spectral distribution of haze of glass used in photovoltaic PV modules. 

BS EN 62805-1 is applicable to glass used in PV modules, including transparent conductive oxide coated (TCO) glass and other kinds of glass used in PV modules. 

Who is BS EN 62805-1- Total haze measurement of PV glass for? 

BS EN 62805-1 on methods for measuring PV glass is useful for: 

• PV glass manufacturers 
• PV module manufacturers 
• PV power system manufacturers 
• Solar cells and solar panel manufacturers 
• Entities involved in the field of solar energy engineering 
• Aerospace and automotive industry 

Why should you use BS EN 62805-1- Total haze measurement of PV glass? 

PV glass is a technology that allows light to be converted into electricity. To do this, the glass contains transparent semiconductor-based photovoltaic cells, also known as solar cells.  

The aim of BS EN 62805-1 is to: 

• Provide specific test methods for measuring haze for PV glass, especially for TCO glass 
• Develop the measurement procedure for spectral distribution of haze in the solar response wavelength range, typically from 280 nm to 1 250 nm 
• Provide the calculation method for total haze in the solar response wavelength range, typically from 280 nm to 1 250 nm 

If you are a manufacturer, adopting BS EN 62805-1 guidelines on precise measurement of the haze values including total haze and spectral distribution of haze, which are important properties of TCO glass, can ultimately enhance the solar cell efficiency.
