Solar Panels on Roofs Not Linked to Higher Cancer Rates: Expert Debunks Myth

CNBC AI News – Recent online rumors claiming a link between rooftop solar panel installations and increased cancer rates in buildings, along with assertions that photovoltaic radiation causes birth defects, prompting pregnant women to avoid such areas, have sparked considerable debate in China.

To address these concerns, experts were enlisted to conduct radiation measurements on various devices, including solar panels, computers, refrigerators, air conditioner outdoor units, and electric kettles.

Xu Honghua, a researcher and Director of the Renewable Energy Integrated Systems Research Department at the Institute of Electrical Engineering, Chinese Academy of Sciences, clarified the terminology. “Solar panel is the colloquial term. The standard technical term is solar photovoltaic module. It does produce radiation, as the concept of ‘radiation’ is very broad.”

“Electrical wires carrying current, televisions, and other electronic devices all emit radiation. The crucial factor is the strength of the radiation to determine if it poses a danger.” According to Xu, all industrial products, when manufactured to standards, have radiation levels that are harmless to humans. “There is radiation, but it is harmless.” The current national safety standard sets the magnetic field radiation limit at 100 microteslas.

Using specialized radiation detection equipment, experts measured the radiation emitted by an operational solar panel. The results indicated a stable radiation value of less than 20 nanoteslas, confirming that the radiation emitted by solar panels is minimal. This is orders of magnitude below the national safety standard.

Furthermore, addressing concerns about the health risks of such radiation, experts explained that household appliances and electronic products, including Wi-Fi routers and mobile phones, adhere to national regulations when manufactured by reputable companies. “In principle, they are safe and will not cause harm to individuals.”

This reassurance comes at a critical time as China aggressively pursues its renewable energy goals. The country is investing heavily in solar energy as part of its commitment to reduce carbon emissions and transition to a greener economy. Concerns about potential health risks could hinder the widespread adoption of solar technology.

The scientific evidence presented by the experts suggests that the fears surrounding solar panel radiation are unfounded. The levels of radiation emitted by solar panels are far below the safety thresholds established by national standards and are comparable to or lower than those emitted by common household appliances.

However, the spread of misinformation highlights the importance of public education and transparent communication regarding scientific findings. Addressing public concerns and providing accurate information is crucial for fostering trust in renewable energy technologies and ensuring the smooth transition to a sustainable energy future.
