Which statement best describes a typical photovoltaic system application?

• A. They require fossil fuels to operate
• B. They power street lighting, NASA satellites, and the grid
• C. They only power portable devices
• D. They produce heat rather than electricity

Answer: (B)

Photovoltaic systems convert sunlight directly into electricity, enabling a wide range of applications from small-scale devices to large grid power. This makes the statement best because it reflects real-world uses of solar power: solar arrays can light streets, provide power for NASA satellites in space, and feed electricity into the electrical grid. Since they generate electricity from sunlight, they don’t require fossil fuels to operate. They aren’t limited to portable devices, and their primary output is electricity rather than heat (heat can be a byproduct, but the main function is electrical power).
