Solar Industry Anxious Over Defective Panels

by Todd Woody, New York Times, May 28, 2013 (excerpts)

The solar panels covering a vast warehouse roof in the sun-soaked Inland Empire region east of Los Angeles were only two years into their expected 25-year life span when they began to fail.

Coatings that protect the panels disintegrated while other defects caused two fires that took the system offline for two years, costing hundreds of thousands of dollars in lost revenues.

It was not an isolated incident. Worldwide, testing labs, developers, financiers and insurers are reporting similar problems and say the $77 billion solar industry is facing a quality crisis just as solar panels are on the verge of widespread adoption....

The solar developer Dissigno has had significant solar panel failures at several of its projects, according to Dave Williams, chief executive of the San Francisco-based company....

Most of the concerns over quality center on China, home to the majority of the world’s solar panel manufacturing capacity....

Executives at companies that inspect Chinese factories on behalf of developers and financiers said that over the last 18 months they have found that even the most reputable companies are substituting cheaper, untested materials. Other brand-name manufacturers, they said, have shut down production lines and subcontracted the assembly of modules to smaller makers.

“We have inspectors in a lot of factories, and it’s not rare to see some big brands being produced in those smaller workshops where they have no control over quality,” said Thibaut Lemoine, general manager of STS Certified, a French-owned testing service. When STS evaluated 215,000 photovoltaic modules at its Shanghai laboratory in 2011 and 2012, it found the defect rate had jumped from 7.8 percent to 13 percent.

In one case, an entire batch of modules from one brand-name manufacturer listed on the New York Stock Exchange proved defective, Mr. Lemoine said. He declined to identify the manufacturer, citing confidentiality agreements.

“Based on our testing, some manufacturers are absolutely swapping in cheap Chinese materials to save money,” Jenya Meydbray, chief executive of PV Evolution Labs, a Berkeley, Calif., testing service.

SolarBuyer, a company based in Marlborough, Mass., discovered defect rates of 5.5 percent to 22 percent during audits of 50 Chinese factories over the last 18 months, said Ian Gregory, the company’s senior marketing director....

Mr. Gregory said repeat inspections of factories found some manufacturers had been constantly switching to cheaper materials, including some whose use-by date had expired.

“If the materials aren’t good or haven’t been thoroughly tested, they won’t stick together and the solar module will eventually fall apart in the field,” he said.

That’s what happened in 2011 at a year-old Australian solar plant, Mr. Meydbray of PV Evolution said. Testing confirmed that substandard materials were causing the Chinese-made modules’ protective coating to degrade, he said. The power plant operator declined to be identified....

All solar panels degrade and gradually generate less electricity over time. But a review of 30,000 installations in Europe by the German solar monitoring firm Meteocontrol found 80 percent were underperforming. Testing of six manufacturers’ solar panels at two Spanish power plants by Enertis Solar in 2010 found defect rates as high as 34.5 percent....

In the Netherlands, René Moerman, chief strategy officer of Solar Insurance and Finance, said claims had risen 15 percent recently. He said an inspection of a solar plant in Britain in March revealed that 12 percent of the newly installed Chinese-made modules had failed. He said confidentiality agreements prevented him from naming the manufacturer....

Non-Chinese manufacturers have had quality problems as well. The defective panels installed on the Los Angeles area warehouse, for instance, were made by an American manufacturer. A reporter was granted access to the project on the condition that the parties’ identities not be disclosed because of a confidential legal settlement.

First Solar, one of the United States’ biggest manufacturers, has set aside $271.2 million to cover the costs of replacing defective modules it made in 2008 and 2009....
