IoT or ‘Internet of Things’ is a concept that has gained prominence over the past decade and refers to the interaction between physical objects that are equipped with intelligence through computing devices.

A valid question in this context would be: why is it relevant in the solar industry?

Anybody with a rooftop solar solution has some sort of monitoring solution associated with it to view the daily energy yield, PR ratio and other parameters. These parameters help assess and monitor the performance of the solar power plant. But, these monitoring solutions have failed to provide the kind of rigorous analytics, insights and observations that would be required especially for large solar power plants, whether it be rooftop or ground-mounted.

Currently there are many state-of-the-art IoT-based solar monitoring solutions offering such advanced analytics. They compile, analyze and manage massive quantities of time-series data generated by sensors such as pyranometers, string monitoring units, energy meters, inverter  data units, etc.

The data acquired from solar plants is stored on the cloud and can be viewed remotely from any place with an internet connection.

Some IoT-based solar monitoring platforms provide excellent performance analytics through provisions for the following:

  • Calculation of performance parameters like Performance Ratio (PR) and Capacity Utilization Factor (CUF)
  • Spatiotemporal analysis of generation
  • Root cause analysis to evaluate factors that impact energy production
  • Offline analysis in case the data has to be downloaded to your system for a much more in-depth analysis
