Quick Answer
Single-axis trackers perform best in weather conditions with significant daily movement, such as clear skies, gentle breezes, and minimal snowfall. They are less effective in areas with frequent strong winds or heavy snow accumulation. Clear days with moderate temperatures are ideal.
Favorable Weather Conditions
Single-axis trackers excel in environments with consistent daily sun movement, typically 90-180° of azimuthal movement. Weather patterns that meet this requirement include clear skies with moderate temperatures (10-30°C/50-86°F) and low to moderate winds (5-15 mph/8-24 km/h). This allows the tracker to efficiently adjust the panel’s angle and orientation to maximize energy production.
Ideal Sun Path Conditions
In areas with high latitudes or extreme seasonal changes, single-axis trackers can still be effective if the sun path is favorable. For example, in locations with a clear winter sky, the sun path can be very low and consistent, allowing the tracker to optimize energy production during this period. In contrast, regions with high summer temperatures and intense sunlight may benefit from a single-axis tracker, as the system can take advantage of the consistent sun movement.
Mounting Height and Tracker Design
The design of the tracker and its mounting height play a crucial role in its performance under different weather conditions. For instance, a tracker mounted on a taller pole may be more susceptible to strong winds, while a shorter mounting height can reduce wind resistance. Additionally, tracker designs with adjustable tilt angles or specialized wind-resistant features can improve performance in areas with harsh weather conditions.
