What is the difference between fixed-tilt and tracking PV systems, and how does it impact energy yield and cost?

What is the difference between fixed-tilt and tracking PV systems, and how does it impact energy yield and cost?

• A. Fixed-tilt has moving parts and higher maintenance
• B. Tracking systems always reduce energy yield
• C. Fixed-tilt has no moving parts and lower maintenance; tracking increases energy yield but has higher initial and maintenance costs
• D. They have identical energy yield and costs

Answer: (C)
