Non-toxic Solar PV as a Source of Green Energy Blends into the Environment Creating Benefits Without Harm
Organization: Bureau of Energy, Ministry of Economic Affairs        Publish Date: 2018-11-26 11:24
In the recent national referendum opinion expression conference, the proposer mentioned that "solar PV panels are toxic and may impact the environment if installed." Ministry of Economic Affairs (MOEA) must solemnly clarify that the manufacturing of solar PV modules, the installation, follow-up maintenance or cleaning does not impact the environment nor the ecology. Rather, solar PV creates maximum benefits for the environment in Taiwan by integrating green energy, ecology, and the environment. Together, MOEA, PV Generation System Association (PVGSA) and Taiwan Photovoltaic Industry Association (TPVIA) express their disappointment with this false statement which is not based on facts and are compelled to refute the ill-founded information.

The main component of a solar PV module is solar cells, whose main material is silicon, a non-toxic substance, whereas the exterior is sealed tight with glass and aluminum frames, which does not dissolve on its own nor leak and cause pollution. Regarding the public concern on whether the installation of solar PV systems over water bodies will contaminate water sources, solar PV panels are installed over water bodies with floating platforms, which is the sole component that will come in contact with water. The floating platforms are made of high-density polyethylene (HDPE), which is resistant to acid, alkaline and dissolution. Global countries including Japan, Korea, and the United Kingdom all had experiences in installing solar PV systems over water bodies, and there have been no reported cases of water polluted this way.

Also, regarding system maintenance, the solar PV systems are mostly installed tilted and therefore capable of self-cleaning-rainwater can wash off dirt, including dust, bird droppings, leaves, and spider webs. Since the exterior of the solar panel is glass, it only requires water (high-pressure waterjet) and instruments such as long handle mop to clean. There is no need for any chemicals at all, and hence does not cause pollution.

Kuo Xuan-fu, Board Director of PVGSA indicated that over 16 billion solar PV modules have been installed in over 200 countries, and so far there has been no reported poisoning incidents caused by solar energy modules. Other than solar floating platforms, all floaters used by floating docks are made of blow molded HDPE. Relevant authority in California even made 96 million PE even placed 96 million PE spheres onto the reservoir to cover water from the sun and reduce the water evaporation. This also demonstrates that PE does not poison the water source by being placed in the water.

According to Chen Kun-hong, Chair of Public Affairs Committee at TPVIA, solar energy power generation does not produce exhaust emissions, wastewater, radiation or other environmental negative impacts. Solar is an energy option that does not burden the earth compared to the other alternatives.

Bureau of Energy reiterates the above facts and strongly calls for a stop to spread misleading information by those with ill intentions. The international society is taking a proactive role in the installation of solar PV, without neglecting ecological and environmental protection.
