Dual-axis solar trackers require regular inspection and maintenance to ensure optimal performance and to prevent downtime due to mechanical or electrical failures. According to industry experts, after the initial startup period, which may require more frequent oversight, dual-axis trackers should undergo periodic checkups to identify and address issues such as loose bolts, damaged gaskets, dangling wires, or motor and sensor problems.
Specifically:
- Initial Phase: Frequent inspections and troubleshooting are critical during the first few months after installation to address startup issues.
- Ongoing Maintenance: After startup, routine physical assessments should be conducted periodically to check mechanical integrity (like tightening bolts), electrical components (checking sensors, power supply, breakers), and replace parts prone to wear (such as gaskets that can crack from sun exposure).
While exact inspection intervals can vary based on system size, environment, and manufacturer recommendations, a common approach is to perform these maintenance inspections seasonally or at least a few times per year to catch early signs of wear and prevent costly repairs later. This schedule balances operational reliability against labor and cost considerations.
In summary, dual-axis trackers should be inspected:
- Frequently during the first few months after installation.
- Periodically thereafter, typically multiple times a year, to check for mechanical and electrical issues and perform preventive maintenance.
