Solar Back Glass for Photovoltaic Modules

Product Advantages

1. High light transmittance

Using ultra-white glass material, the light transmittance can usually reach more than 91%, which can allow more light to pass through the back glass to reach the battery cell, reduce light loss, and improve the power generation efficiency of the component.

2. Good insulation

It has excellent electrical insulation performance, and the insulation resistance can reach more than 1000MΩ·cm, which can effectively prevent the battery cell from leaking electricity from the outside world and ensure the safe operation of the component.

3. Strong mechanical properties

Through special tempering process treatment, it has high impact strength and bending strength, can withstand wind loads of more than 2400Pa and snow loads of more than 500Pa, and can withstand harsh natural environments.

4. Excellent weather resistance

It has excellent resistance to high and low temperatures, humidity and heat, and UV rays. It can work stably in the temperature range of -40℃ to 85℃. After more than 2000 hours of humidity and heat tests and more than 500 hours of UV tests, the performance has no obvious decline.
