Polarized light glinting off solar panels acts as an attractant to aquatic insects that see polarized light as a water indicator. Solar arrays are lethal to aquatic insects because the insects, mesmerized by the polarized light, fly over the solar panel surface until they die of exhaustion. Insects are important because they are food for fish and other species.
Knowing that solar arrays are lethal to aquatic insects provides more reason to locate solar projects in cities and developed areas rather than disrupt the pristine habitat of deserts and other fragile eco-systems.
