Entrack – Solar Plant Monitoring Device

The solution was designed to serve a client who had a Solar Farm, generating 40 MW power with approximately a hundred thousand solar panels installed. Naturally, monitoring individual panels for their average power generation data and keeping a check on their working condition was not possible manually.


The customer wanted a solution to monitor individual solar panel from central control room. This project precisely aimed at creating a low power device that would measure individual panel performance and promptly intimate any functionality fault.


The major challenge was to create and test a system that connects to each panel, 24 hours a day.


  • Monitor, measure and report power generated from solar panels
  • Measure panel level performance
  • Indicate underperforming panel within no time
  • Real-time status management of solar panels through a sophisticated CMS
  • ZigBee based 2.4Ghz communication technology


Volansys was involved right from understanding client’s problem statement to provide final tested and workable solution.

Volansys came up with a low-power wireless mesh networking device to build a mesh network and transfer data to central control room over the wireless interface with power measurement timing frequency as low as 5 minutes.
