Defective PV module product or fire

According to reports, a large number of defective components may threaten the photovoltaic industry.

According to the Wall Street Journal, U.S. utility companies such as U.S. power companies that rely on coal to generate electricity are planning to install photovoltaic modules for businesses and homes—a company that has been installed with distributed photovoltaic systems, such as SolarCity, as a threat.

In Boston, USA, First Wind, a wind farm developer, is moving into solar PV. The company plans to acquire a large number of photovoltaic projects in New England, Hawaii, Utah and Washington.

According to the “New York Times” report, all of the above photovoltaic power generation projects may contain a part of photovoltaic modules that are far from reaching their warranty period. According to a report published by the headquarters of SolarBuyer in Marlborough, Mass., in the past 18 months, in the review of 50 Chinese factories, the product defect rate reached 5.5% to 22%.

"The New York Times" pointed out that after a large-scale rooftop power generation system located in the eastern part of Los Angeles, USA, only two years after the operation, the decomposition of protective coatings and other defects may cause fire.

According to Todd Woody of The New York Times, this is not a case. Similar problems have been reported from test labs, developers, financing agencies and insurers around the world, and they said that the value of the $77 billion photovoltaic industry is facing a quality crisis when PV modules are almost universally used.

Conrad Burke, general manager of the DuPont Photovoltaic Division, told reporters that we need to face the fact that costs have been continuously reduced.

However, the "New York Times" did not mention the name of the photovoltaic manufacturing company.
