Challenges for Solar Tracking System

  • Periodic inspection and lubrication is required since there are many moving parts especially motor.
  • The higher capital costs of installations, together with a perception of lower reliability are potentially making tracker developments more difficult to finance.
  • On-going operations and maintenance costs also are higher.
  • As the costs of silicon-based modules fall because of greater production, a key driver for the installation of trackers – maximizing their output to improve return on investment, becomes less critical.
  • With a lower overall efficiency, thin-film modules require more tracker units for a given level of output, increasing their relative cost in a project’s development.
  • Developers not only have to consider cost and location but the type of tracker that best suits the project.
  • A major consideration when using trackers is land use. They generally take up much more land than fixed systems because their movement can create shadows which can affect neighboring panels, so they must be spaced appropriately.
