The fire may have been caused by the photovoltaic system, which burned more than 1,500 square meters of heat shields and produced a large amount of smoke, causing tens of thousands of laying hens to suffocate in the shed.

A few days ago, according to the latest reports, a photovoltaic laying hen farm in Treviso, Italy caught fire. Firefighters from the three cities of Montebelluna, Castelfranco, and Treviso provided assistance at the scene of the fire. , A total of three fire trucks and 16 personnel were used to put out the fire.

According to firefighters, the fire directly killed more than 20,000 laying hens in the farm. As for the cause of the fire, the local fire department stated: “The fire may have been caused by the photovoltaic system, which burned more than 1,500 square meters of heat shields, and produced a lot of smoke, causing tens of thousands of laying hens to suffocate in the shed.”

In recent years, with the promotion of low-carbon production, photovoltaic smart chicken farming has become popular both at home and abroad.

For example, Chongqing Ruisang Agriculture, the first photovoltaic smart chicken farm put into operation in my country in 2022, said that the roof of the chicken farm with an area of 3,000 square meters has been fully installed with solar photovoltaic panels, and the annual power generation is expected to be more than 70. Wandu can not only solve the problem of self-use of chicken farms, but also provide surplus for online use. This comprehensive utilization is equivalent to planting 3,700 trees, saving 2,640 tons of coal for power generation, reducing carbon dioxide emissions by 650 tons, and reducing dust emissions by about 180 tons .

And in March of this year, the government of Taizi Town, Shandong Province stated that it would seize the opportunity of a pilot town in the photovoltaic industry and attract 100 million yuan to develop the “complementary animal husbandry and light” of laying hens on seven acres of land and the “complementation of fishery and photovoltaics” in more than 200 acres of bay ponds. project.

It is understood that the ecological breeding project of Shandong Qimudi Agriculture and Animal Husbandry Technology Co., Ltd. with 1.2 million feathers of pollution-free laying hens is one of the local projects to promote the modernization of animal husbandry.

However, in recent years, there have been many cases of serious losses caused by photovoltaic power generation fires. According to previous reports, the photovoltaic system is a relatively complex electrical system, and the system design is unreasonable, too complex or too simple, which may cause problems; for example, too long DC cables, incorrect connection of solar panels etc., will lead to excessive voltage and current and cause a fire. In addition, equipment failure, power station system attenuation, equipment aging, maintenance and repair technical errors are also extremely important reasons for power station safety risks.

In order to prevent and reduce the risk of fire in the photovoltaic system, if laying hen farming enterprises build photovoltaic smart chicken farms, it is recommended to pay attention to safety during the design, construction and operation of photovoltaic systems, and strengthen equipment maintenance and regular inspections , to make sure the device is functioning properly.

At the same time, set fire belts around the photovoltaic system, install fire extinguishing equipment (install fire extinguishing equipment around the photovoltaic system, such as fire extinguishers, fire pumps, etc., so that fire can be extinguished in time when a fire occurs), and set up safe passages (set up safe passages around the photovoltaic system) , to facilitate fire vehicles and rescue personnel to enter and leave the scene) and other safety measures can also effectively reduce the probability of fire in the photovoltaic system.

Once the power facilities of the photovoltaic power station catch fire, we must first shut down the inverter immediately, cut off the AC power supply, and then disconnect the photovoltaic string circuit as soon as possible to completely cut off the arc source of the photovoltaic string. Inform and remind the firefighters of the electrification of the photovoltaic equipment on the roof as soon as possible, and it is best for firefighters to wear insulating shoes. Do not touch your body and the fire extinguisher in your hand to live wires or electrical equipment to prevent electric shock accidents during fire extinguishing. At the same time, it is necessary to keep a certain distance when using equipment to extinguish the fire.

The most important thing is to choose a high-quality inverter that can provide good after-sales service. shenzhenbuyit is a manufacturer specializing in inverters, batteries, and solar panels. You can totally trust them. If you want to contact them, you can add whats app: 008613808405352
