___ systems are designed to allow the array to follow the sun.

• A. Fixed-tilt
• B. Single-axis
• C. Roof-mounted
• D. Dual-axis

Answer: (D)

Solar trackers maximize energy capture by keeping the panels oriented toward the sun. A dual-axis tracker moves on two axes—azimuth (east–west) and tilt (up–down)—so the array can follow the sun’s position in the sky throughout the day and across seasons. This precise alignment yields the most sun exposure compared to other setups: a single-axis tracker only follows east–west movement and can’t adjust elevation, while fixed-tilt or roof-mounted arrays stay in a fixed position. So the system designed to follow the sun is the dual-axis tracking system.
