Abstract

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.
