The rapidly expanding manufacture of solar photovoltaic products is risking serious environmental pollution. According to Greenpeace and the Chinese Renewable Energy Industries Association, some two-thirds of the country's solar-manufacturing firms are failing to meet national standards for environmental protection and energy consumption.
The negative effects of solar photovoltaic system production include wastewater and waste gas pollutions, the representatives of which contain fluorine, chromium with wastewater and hydrogen fluoride, and silicon tetrachloride gas. Solar panels are also a source of light pollution.
The positive and negative aspects of solar photovoltaic technology, a novel technology, should be comprehensively considered. Solar energy is abundant, and its depletion is unlikely. The generation of solar photovoltaic systems does not cause any type of pollution and requires no energy consumption.
Insufficient toxicity and environmental risk information currently exists. However, it is known that lead (PbI 2), tin (SnI 2), cadmium, silicon, and copper, which are major ingredients in solar cells, are harmful to the ecosystem and human health if discharged from broken products in landfills or after environmental disasters.
Solar panels are also a source of light pollution. Improper disposal of solar cells that have reached the end of their service life harms the environment through the stench they produce and the damage they cause to the soil.
The manufacturing of solar cells involves several toxic, flammable and explosive chemicals. Many of those components suppose a health hazard to workers involved in manufacturing of solar cells. Solar panels are often in competition with agriculture and can cause soil erosion.
