Figure 1: The Digital Twin of the Solar Plant was present on the SenseHawk platform right from start of construction
Figure 3: The SenseHawk Therm application identified and classified over 3500 defects on the plant
Figure 4: Each defect resulted in the creation of a task that could be assigned to members of the field team
Figure 7: Field investigation for this defect revealed broken glass on the module – a manufacturing defect. Photographs of the damaged modules were attached to the associated task.
Figure 8: Results of the field investigation were summarized in excel for easy reporting to the Owner and to the OEM for warranty claims
The excel clearly indicated the resolution status of each defect – some of them were resolved on the field, while many others (over 3500) were liable for warranty claims (the photos and other attachments made to each defect provided a quick and easy way to verify this). The EPC therefore submitted the excel file to the owner, who was satisfied that the defects were either already rectified or would be rectified through warranty claims, and cleared this particular punch list item from the EPC’s list. All this was done within 10 days of the thermal reports being made available to the EPC, well within the commissioning deadline.
Post-commissioning, the actual task of warranty claims remained. The serial numbers that had been meticulously cataloged prior to the thermal scan, proved to be very useful. Each defect had the corresponding module serial number associated with it. The owner was able to simply send a list of defective serial numbers to the OEM, who was able to quickly verify the claims using evidence already gathered during the on-field investigation.

In this manner, a seemingly gargantuan task was completed in less than three weeks. The plant was operating at maximum efficiency from day one, and the usually complicated task of warranty claims was reduced to a simple checklist activity.
