Raytech has received a lot of positive feedbacks from clients because of its high strength of double-glass structure. The front glass layer of solar module is usually made of low iron ultra-white tempered glass, which has a certain hail proof ability and can withstand the general hail strike.

As a high-quality solar module manufacturer, Raytech will do mechanical testing for its very model of solar modules. A 25mm diameter steel ball is usually used to impact the PV module at a speed of 23 m/s to test its mechanical performance. After passing the test, it will be sold in the market.

The diameter of common hail is 5 to 10cm, the density of hail is about 700 to 800kg per cubic meter, and the falling speed of hail is usually 20-30m/s or more. In this case, solar modules will not be damaged.

Hail with a diameter of more than 8cm is a rare-probability event. In this case, most PV modules cannot survive from the disaster. 8cm hails not only damage solar modules, but also cracks your house roof tiles.

Raytech’s all range of solar panels have obtained TUV Certifications and other safety testing including lightning protection test, the high quality and consistent product performance have been widely recognized globally. In 2021, Raytech will continue to focus on providing high-quality solar panels and 24/7 service to our clients.
