Why Solar Trackers Turn Panels During the Day
Why Solar Trackers Turn Panels During the Day
A moving rack changes panel orientation as the sun crosses the sky, trading mechanical complexity for additional output.
A single-axis tracker typically rotates a row through the day. The controller can also adjust its position to reduce shading from one row onto another.
Tracking adds motors, bearings and controls that need maintenance. Strong winds may require the rows to move to a protective position, temporarily changing generation.
Compare production by hour and season against a fixed mounting system. The value of extra generation depends on local sunlight, electricity prices and the cost of maintaining moving equipment.
