Our customer is a Subsidiary of one of the World’s largest Independent Power Producer (IPP) (of Clean and Renewable Energy). They were actively seeking a robust solution to enhance the efficiency of their field deployed Solar Tracking Systems.
During the evaluation and PoC stage, a need to remotely update the Field Gateway Device ( Master Controller) software was realized. This remote management of the software of the Gateway device was necessary to facilitate the following:
During software updates of the system, the customer also wanted to ensure the following:
Once the scope of the project scope was defined, our team started the ground work for FOTA (Firmware update Over The Air) implementation.
The Technology roadmap for FOTA Solution Development roadmap comprised of the following:
Following is a representation of the FOTA cloud server architecture:
It was decided to schedule all the batch processes of the FOTA update after sunset evenings. Reason – this ensured uninterrupted generation of energy by the solar panels.
This would also ensure that the FOTA updates are implemented without affecting the normal operations of the Solar Harvesting systems and lead to minimized system downtime.
Integration of such a well-defined and robust FOTA update mechanism helped us deliver the following business value-adds:
