Environmental damage analysis of solar panels

Among the many features that make solar panels attractive, the most prominent is their environmental benefits. Especially for areas with serious environmental problems, sources of power generation without pollution emissions are very important. However, despite having many advocates, solar energy is not completely harmless to the environment. Understanding this is critical to the technical support and proper installation of the equipment.

An important indicator of the environmental impact of solar panels is the so-called energy payback period. It refers to the length of time that solar energy equipment begins to invest in maximum capacity. In 2004, the National Laboratory for Renewable Energy calculated that the energy return period of polycrystalline solar cells is about 4 years, and the energy return period of thin film batteries is three years. This cycle will continue to decrease as production processes and solar cell conversion rates improve. The recent report by the Convergence Solar Cell Alliance and the University of California, Berkeley, pointed out that the best results of the polymer photovoltaic solar system. In any case, ordinary user-side solar equipment generates at least 16 years of positive net income.

Another important issue is the land of solar panels may be caused by abuse, large-scale solar farms may impact on the ecosystem. According to reports, at least one utility-level power plant was suspended due to environmental hazards caused by sea turtles. It is not difficult to solve this problem because commercial and residential buildings are also equipped with power generation equipment.

In addition, toxic chemicals in the manufacture of solar panels may also pose a threat to workers' health, but this hazard is minimal compared to other industries.
