Shanghai, January 11, 2021 – ZNShine Solar has received the Fire Class A certification according to the IEC 61730-2 standard (UL 790). The certificate applies to the entire double glass product range from ZNShine Solar.

All electrical installations are by nature carrying a certain degree of fire risk and fires from solar modules are not impossible even though they are very rare. In recent years, countries have increased requirements for the fire rating of PV power stations, especially solar modules.

The solar modules’ fire performance has become an important consideration for the PV power station building, especially for roof installations. A high-quality solar module, that is properly installed and maintained, should not create a bigger fire risk than any other electrical home appliance.

 To obtain the fire resistance classification the modules must undergo a spread of flame test and a burning brand test during which the flame spread and flammability of the products are evaluated.

As one of the leading solar manufacturers, ZNShine Solar’s double glass modules successfully passed the Class A Fire test in accordance with the UL790 standard.

Fire Classification refers to a fire-resistance rating system for the roof covering materials based on their ability to withstand fire exposure. This standard includes three classes of fire protection levels, according to the fire source exposure:

• Class A roof coverings, which are effective against severe fire test exposures;
• Class B roof coverings, which are effective against moderate fire test exposures;
• Class C roof coverings, which are effective against light fire test exposures.

In conclusion, the Class A Fire protection performance of ZNShine Solar’s double glass modules indicated that the company’s manufacturing experience has reached the leading level in the industry.
