Condition based solar PV plant maintenance and monitoring using sparse, low cost sensors

Solar PV plants need to be maintained if they are to continue to work at their rated output and efficiency. But there are various failure modes observed in a PV installation. It is not practical to equip every module with sensors to detect failure modes. Therefore, the project aims to use sparsely placed, low cost sensors and a robust analytics engine to

  • Identify and localise failure modes and reduce plant downtime and repair costs.
  • Optimise plant cleaning schedules (thus reducing usage of water required to clean panels).
  • Improve plant output and efficiency.
