The Dutch football stadium collapsed because of rooftop solar panels? Results: no relationship!

Solar photovoltaic (pv) net news: in the middle of August, 2019, local collapse accident alkmaar football stadium roof. At that time, most of the Dutch media in reporting stressed that when the solar panels on the roof could be the main cause of the accident. The accident caused no casualties, because the venue is in the idle state.

team general manager Robert & middot; Mr Hoon announced that will be an investigation into the matter immediately. Today, from the accident has over the past eight months, the Dutch engineering consulting firm, and finally released the results of the survey group. The company made it clear that China solar power network, the cause of the roof collapse, is not the solar panels.

and wei group of companies in the survey report points out that partial collapse AFAS stadium roof, is due to the stadium at the top of the steel beam connection due to loose. Report also mentioned that solar energy equipment, local winds during the storm, is the cause of the accident. The company explained that the stadium roof beam welding process is the key problem.

　　“ The welding joint is too thin, make steel to withstand at least fell by 50%, & throughout; In the report, the company has denied the is generally accepted that the roof of the solar panels collapsed conjecture, and further, said & other; The design of the roof beam has a problem. Thought could trigger a collapse of other reasons, did not play a big role in the accident. ”

Germany photovoltaic power industry research co. , LTD. The wind load, head of sotheby's teng & middot; Tell pv magazine in August, clay roof collapse due to the wrong design calculation.

　　“ I have a quick look at the news push, solar equipment, & throughout; He said at the time, & other; And, I don't think solar panels is the root cause of the storms the roof collapse. If the roof steel structure design is reasonable, accurate calculation, and takes into consideration the dead load of solar panels, photovoltaic panels don't may be the cause of this collapse. ”

clay cited a large number of scientific publications on embedded photovoltaic panels and solar equipment, these publications all show that the parallel to the roof solar system will not increase the static wind load of the roof.
