Digital New Energy DataBM. Com learned that on November 7, a fire broke out on the top floor of a high-rise building in Ao Town, Qionghai City, Hainan Province, and nearly 200 square meters of photovoltaic solar panels on the top floor ignited a raging fire, but fortunately no casualties were caused. The fire department of Qionghai City is investigating the cause of the fire.
From the scene pictures, most of the photovoltaic panels have been burned down. According to people familiar with the situation, the cause of the fire was probably caused by the unqualified components installed. The owner of the photovoltaic panel on fire had asked him to buy the photovoltaic panel, but the owner thought the cost was high, so he bought the products of an unknown company on the Internet and found someone to install them. After the installation of grid-connected power generation, the photovoltaic panel has the problem of burning the backplane of the module because of the excessive current of the photovoltaic module.
"The thickness of the three-wire welding on the backplane of the unqualified component products is not enough, and the current of the wire is easy to overheat and burn the backplane under the light, while the landlord has installed a thermal insulation layer under the backplane, which is more flammable under the burning of the electrolyte." Insiders revealed in an interview with the media. & nbsp; & nbsp; & nbsp; In recent years, PV fire accidents have occurred frequently. In August
2019, the US retail giant Wal-Mart sued Tesla for a rooftop photovoltaic fire; in June 2021, a rooftop photovoltaic fire broke out in Baoshide, Suzhou; in August this year, a rooftop photovoltaic fire broke out in a laying hen farm in Treviso, Italy..
