The cost of dual-axis solar trackers is significantly higher than that of single-axis trackers. This is primarily due to the increased complexity and functionality of dual-axis systems, which require additional components such as sensors, motors, and control systems to adjust the solar panels both horizontally and vertically. Despite their higher upfront costs, dual-axis trackers can increase energy production by up to 40% to 45% compared to fixed panels, potentially offering a faster return on investment (ROI) over time, especially for large-scale solar installations or areas with seasonal sunlight variations.
Key Cost Differences:
- Initial Costs: Single-axis trackers are more budget-friendly and easier to install, making them suitable for projects with budget constraints.
- Maintenance Costs: Dual-axis trackers may incur higher maintenance costs due to their complexity and more moving parts.
- Energy Efficiency: Dual-axis trackers offer higher energy efficiency, which can lead to savings and increased power output over time.
Cost per Watt:
- The installed cost for a single-axis tracker typically ranges around $0.91 to $1.00 per DC watt for fixed mounts.
- The cost for dual-axis trackers is generally higher, with an additional premium of about $1.33 per watt compared to fixed mounts, resulting in a total cost of around $9.96 per DC watt.
Overall, while dual-axis trackers are more expensive upfront, their superior energy efficiency can provide long-term financial benefits, especially in certain solar market conditions.
