Photovoltaic panels power which of the following?

• A. only small devices
• B. almost everything, including street lighting, NASA satellite equipment, and even the grid
• C. only remote sensors
• D. only residential roofs

Answer: (B)

Photovoltaic panels convert sunlight directly into electricity, and they come in a wide range of sizes and configurations. That versatility means they’re not limited to a single use—they can power everything from tiny devices to large-scale electrical systems. Solar panels are used for street lighting, on satellites and spacecraft (including NASA equipment), and for generating electricity that feeds into the power grid through large solar farms. When paired with storage or a connection to the grid, they can provide power across different times and loads. This broad applicability is why the best answer describes PV panels as powering almost everything, including the examples listed.
