Comparison of Single-Axis and Dual-Axis Solar Trackers in Terms of Energy Yield
When comparing dual-axis trackers to single-axis trackers in terms of energy yield, several key differences emerge:
Single-Axis Trackers
- Energy Increase: Single-axis trackers improve energy output by about 25-30% compared to fixed tilt systems. They typically follow the sun from east to west.
- Efficiency and Cost: They are noted for being more reliable, having a longer lifespan, and being cheaper to install and maintain than dual-axis trackers.
- Suitable Applications: Ideal for large-scale projects, cloudy areas, or those with limited budgets due to their simplicity and lower cost.
Dual-Axis Trackers
- Energy Increase: Dual-axis trackers can increase energy output by an additional 5-10% over single-axis trackers, achieving a total efficiency increase of about 35-40% over fixed tilt systems.
- Flexibility and Space: They continuously adjust to track the sun in any direction, providing the highest energy yield. Despite requiring more maintenance and being more expensive, they can optimize space usage for other purposes.
- Suitable Applications: Better suited for smaller-scale projects or areas with complex terrains where maximizing energy yield is critical.
In summary, while single-axis trackers offer a cost-effective and reliable option with a significant efficiency boost, dual-axis trackers provide the highest possible energy yield at the expense of higher costs and more complex maintenance.
