Failure Rates for PV Panels Are Climbing

Manufacturing shortcuts, most of them at Chinese factories, are leading to higher failure rates for photovoltaic (PV) Generation of electricity directly from sunlight. A photovoltaic cell has no moving parts; electrons are energized by sunlight and result in current flow. panels and prompting growing concerns among testing labs, insurers and solar developers, The New York Times reports. In an article published May 28 , the newspaper said that inspections over the last 18 months have discovered that "even the most reputable companies are substituting cheaper, untested materials" in their PV Photovoltaics. Generation of electricity directly from sunlight. A photovoltaic (PV) cell has no moving parts; electrons are energized by sunlight and result in current flow. modules. Chinese companies borrowed a lot of money to ramp up manufacturing and are now under intense pressure to...
