These are significant changes that promote plant growth and the development of microscopic organisms that affect soil fertility.
Solar energy is currently considered very promising, although there are certain concerns regarding the environmental impact of solar panels during operation and especially after their lifespan ends. However, at least in some situations, solar panels seem to have a tangible positive effect on the ecology. This is reported by Futura Sciences.
A new study conducted in the Talatan Desert in western China shows that the solar panels installed there have created their own microclimate, altering the soil composition and promoting vegetation growth.
Researchers from Xi'an Technological University examined a large one-gigawatt solar power plant occupying a significant area in the barren desert. The team analyzed 57 ecological indicators, including soil chemical composition, temperature, humidity, and biodiversity.
The study found that the overall "health" of the soil directly under the solar panels is twice as good as the bare soil of the desert. The reason is quite obvious: the panels provide constant shade, retaining moisture and lowering soil temperature. In desert conditions, where water is already scarce, these are significant changes that promote plant growth and the development of microscopic organisms that affect soil fertility.
Researchers suggest that large solar power plants could be not just a source of energy for human civilization, but also a tool for revitalizing desert areas. At the same time, the researchers note the need for further studies to explore this effect over long periods. Scientists also point out that each desert is unique in its own way, and the effect will not be the same everywhere.
However, the infrastructure for recycling old solar panels is lagging behind the development of the solar energy industry, and the presence of hazardous materials in solar panels complicates disposal in landfills. Without regulatory intervention, this could lead to serious environmental harm.
