Floating solar panels are installed in areas that have limited land but large water bodies. It is observed that these panels have been beneficial in preventing algal blooms, which require warm water to grow. How do floating solar panels help prevent algal blooms in water bodies?

Question

A. They eliminate the underwater plants that algae rely on for nutrients.
B. They reduce the space available for algae to grow by covering the water's surface.
C. They increase the water's temperature, creating a less favorable environment for algae growth.
D. They limit the amount of sunlight that reaches the water's surface, reducing the photosynthesis of algae.

Answer 1

Floating solar panels help prevent algal blooms primarily because D. They limit the amount of sunlight that reaches the water's surface, reducing the photosynthesis of algae. By covering the water surface, the solar panels reduce the light available for algae, which in turn can limit their growth and proliferation. This can help maintain better water quality and prevent algal blooms that can be harmful to aquatic ecosystems.
