Solar glass specifications and standards

What G-value should a Photovoltaic Glass have?

Photovoltaic glass can be customized to achieve a solar factor between 6% and 41%. A low g-value is desirable to prevent overheating, especially in warm climates, as it prevents the interior temperature from rising too high due to the greenhouse effect.

What is a solar glass substrate?

Manufacturers of crystalline silicon solar modules apply glass substrates on the front side of the solar modules. This front glass will either be a patterned glass or a glass with anti-reflective coating (AR). As in all other glass manufacturing processes, solar glass substrates are subject to defects during produc-tion.

How can solarinspect ensure the quality of the finished modules?

To ensure the quality of the finished modules, the control of the dimensions and shape (rectangular-ity) of the glass substrates is essential. SolarInspect provides this capability parallel to the glass defect detection.

What happens if a solar glass substrate is defective?

As in all other glass manufacturing processes, solar glass substrates are subject to defects during produc-tion. Depending on the defect type and intensity, the impact of these defects can range from a reduced transmission to a considerable negative influence on the mechanical glass characteristics.
