Quick Answer
Mistakes in installing solar trackers include poor leveling, inadequate mounting, and neglecting tracking efficiency, which can reduce the system's overall energy output.
Incorrect Mounting and Leveling
Incorrect mounting and leveling of solar trackers can lead to reduced efficiency and lifespan. Ensure the tracker’s mounting system is sturdy and levelled within 1-2° to prevent excessive stress on the tracker and panels. A minimum of 3 screws per corner is recommended, with a minimum screw torque of 30 Nm for 14mm screws.
Poor Tracking Efficiency
Poor tracking efficiency can be attributed to factors such as misaligned tracking axes, inadequate tracker calibration, and insufficient maintenance. Regularly check the tracker’s alignment and adjust as necessary. Most modern solar trackers come with built-in self-calibration capabilities, which should be enabled at the beginning of the system’s operation.
Inadequate Cable Management and Grounding
Inadequate cable management and grounding can lead to electrical issues and system downtime. Ensure all cables are properly secured, routed, and grounded to prevent electrical shock and system failures. Use a minimum of 6mm² (10 AWG) copper cables for solar tracking systems, and ensure the grounding system meets local electrical codes and regulations.
