Chinese Solar Panel Pollution

Chinese air pollution dimmed sunlight enough to impact solar panels.

Chinese solar panel pollution.

The cost of a kilogram of silicon crystal stands at about us 13 this year. Panels produced in china which relies heavily on coal for power have a larger carbon footprint than those produced in europe. At a three day international solar panel exhibition in may hundreds of solar panel manufacturers and buyers convened in shanghai. Solar panels generate 300 times more toxic waste per unit of energy than nuclear power plants.

But the view from solar panel factories is sometimes a little different. Solar panel manufacturers need electricity and thermal energy and carbon emissions from their generation can vary widely with location. Rather the quotes come from a senior chinese solar official a 40 year veteran of the u s. New research shows that such smog not only dims the daylight and makes the air hard to breathe but it reduces the amount of sunlight reaching china s solar panels.

Solar industry and research scientists with the german stuttgart institute for photovoltaics. In 2015 china became the world s largest producer of photovoltaic power narrowly surpassing germany. China is halting construction on new coal powered plants that emit the hazardous pollutants that often choke cities in a thick blanket of toxic smog. They also contain lead cadmium and other toxic even carcinogenic chemicals that cannot be removed without breaking apart the entire panel.

According to new research china s coal driven air pollution is significantly reducing the output of solar panels by dimming the sun. Recycling china s vast numbers of solar panels could prove to be expensive and time consuming. China s rapid economic expansion was largely fuelled by coal which lifted millions of people out of poverty but also drove up levels of air pollution. China is the world s largest market for both photovoltaics and solar thermal energy since 2013 china has been the world s leading installer of solar photovoltaics pv.

Protests last month exposed pollution problems at a manufacturing site in zhejiang province which according to industry insiders are just the tip of the iceberg. Worse rainwater can wash many of these toxics out of the fragments of solar modules over time. Smog smothers solar energy in china 2003 2014 png on some hazy days particularly in winter china s skies are blanketed by white and gray clouds of air pollutants. In 2017 china was the first country to pass 100 gw of cumulative installed pv capacity and by the end of 2018 it had 174.
