Solar photovoltaic panels are harmful to birds

Does solar energy affect bird populations?

Solar energy has emerged as a promising alternative to traditional fossil fuel-based energy sources. As the demand for clean and renewable energy grows, it is important to assess the potential environmental impact of solar installations. One of the key concerns associated with solar energy development is its impact on bird populations.

How do solar panels affect wildlife?

The vast expanses of solar facilities (also known as 'solar parks' or 'solar farms') have unique impacts on fauna that we are only just beginning to identify. The reflective surfaces of solar panels can attract insects (e.g., [, ]), providing new feeding opportunities for bird and bat species (e.g., [, , , ]).

Are solar panels killing birds?

At the end of 2023, an estimated 37,900 km 2 of the earth's surface was covered by solar facilities, which are likely to be killing an estimated total 17.3 million birds per annum. The vast expanses of solar panels as part of utility-scale solar facilities are a new type of anthropogenically transformed landscape.

Do solar panels attract insects and birds?

Novel habitat and foraging resources at solar facilities attract insect and bird species. Wildlife community composition reflects increases in species richness and abundance. Generalist species benefit. Insects and waterbirds are attracted to polarised light reflections from solar panels.
