Solar Energy’s Environmental Impact: Separating Fact from Fiction on Floating Panels

The recent spread of misinformation surrounding solar energy in Taiwan has created new obstacles for the government’s renewable energy expansion efforts, particularly after Typhoon Danas damaged floating photovoltaic arrays in the southwestern region of the country in early July.

Following the typhoon damage, a video began circulating online that appeared to show a bird drinking from a reddish puddle near broken solar panels, then suddenly collapsing and dying. This footage quickly fueled public fears that toxins from damaged panels were contaminating water sources, especially concerning since Taiwan has deployed photovoltaic systems on multiple reservoirs and fish farms.

Taiwan’s Ministry of Environment responded swiftly, conducting on-site tests at Sinjhuang Flood Detention Pond in Chiayi County’s Yijhu Township on August 7. The tests detected neither heavy metals nor oil in the water, with normal pH levels. Officials attributed the reddish water coloration to naturally occurring humic acid in the soil.

Environment Minister Peng Chi-ming personally inspected the site on August 16, confirming that cleanup operations were proceeding “in accordance with regulations.” Despite these assurances, cleanup challenges remained. More than a week after the minister’s visit, debris from broken panels was still visible around the pond, resulting in a NT$9 million fine for the operator. The company tasked with clearing the site explained that the process was time-consuming, requiring panels to be separated from floats before transport to specialized processing facilities.

The Taiwan FactCheck Center (TFCC), an NGO accredited by the International Fact-Checking Network, later revealed on August 25 that the bird-death video had been AI-generated—a fact the original creator had actually acknowledged when posting the clip on Threads, though their account later disappeared.

This incident represents just one of many cases of solar energy misinformation that TFCC has addressed. The center has published 13 reports on solar power misinformation over the past two years alone. Recent examples include debunking rumors about water quality at Tainan’s Wushantou Reservoir following installation of a major floating PV system. Some social media users had misinterpreted transparency-index data, while others falsely claimed that water tests had detected cleaning agents in concerning quantities.

TFCC Deputy Editor-in-chief Chen Pei-huang explained that most of these narratives originate from social media or online forums. “They often combine genuine concerns about environmental impact with misinformation or misleading visuals,” he said. “In our assessment, the majority are not deliberately malicious but stem from misunderstanding, incomplete information or distrust toward renewable-energy policies.”

The impact of misinformation is amplified by influential figures with large social media followings. One Taipei chest physician with 121,000 Facebook followers shared unsubstantiated claims about water quality at Wushantou Reservoir. His post garnered approximately 39,000 reactions and was shared over 1,200 times—significantly outperforming TFCC’s fact-check on the same topic.

Solar energy critics don’t always need to rely on fabricated content to generate skepticism. A recent Control Yuan report titled “Questions Concerning Photovoltaic Project Applications” documented legitimate concerns about corruption and market distortion in Taiwan’s solar energy sector. The report cited instances of organized crime infiltrating the industry, with gangs sometimes mobilizing protests under the pretext of environmental concerns to extort money from companies.

The report also highlighted issues with the government’s “aquaculture-electricity symbiosis” policy, which encourages fish farmers to install PV systems over their ponds. While the report criticized this approach as essentially “using electricity revenue to subsidize fisheries,” others view it as a practical dual solution for Taiwan’s energy and food security needs.

As Taiwan continues to expand its renewable energy capacity, addressing both misinformation and legitimate industry concerns will be crucial for maintaining public support and ensuring sustainable implementation.
