Inspection for solar site maintenance

Use our report to identify and locate solar site maintenance issues.

Specifically, the report enables maintenance crews to:

 

  • Review a list of defects identified during a solar site inspection.
  • Prioritize each anomaly, enabling the most serious issues to be addressed first.
  • Find the defective components on the ground so that they can be repaired or replaced.


Review the following to learn how we use Raptor Maps to identify, prioritize, and locate defects requiring maintenance attention. The example is based on a Raptor Maps Standard inspection, which identifies anomalies to the diode, hot spot, and cell level.

Note that Raptor Maps also provides APIs to enable us to directly integrate Raptor Maps analytics with your work order management system. Contact us for more information.

Once your report is available, find the list of findings in the Report view:

Findings:

The list shows that four strings are defective, impacting 76 modules. These anomalies have the greatest impact on power available, and so have highest priority for maintenance.

We can adjust the power purchase agreement rates used to calculate the estimated annual impact, let us know if you have a specific value you want us to use for the report.

To assign priority, scroll down the report to the Anomaly Location table:

Based on historical customer feedback, Raptor Maps analytics has assigned a high priority to these string anomalies. However, it can be changed to the specific priority every asset has (the anomaly that is creating major power losses).

Next, determine where the defective strings are located. From the Report view, click on the Globe icon in the left-hand toolbar to go to the Map view.

In this Map view, we’ve used the Map Layer Option to restrict the display of anomalies to those related to Strings:

Use the site map and location information associated with the anomaly to find the defective component on the ground.

 

Expert tips:

From the map view, we can click on the appropriate export icon to export the anomaly and mapping data to a file for upload to mapping software such as Google Earth, as shown below. The .shp file provides compatibility with ArcGIS and QGIS.

Import the files to mapping software and it will provide the latitude and longitude for each anomaly:

To better understand the numbering scheme
used to reference anomaly location, review the Localizing Anomalies section in the report view. The numbering scheme is either provided by the customer or is the Raptor Maps default.

You can have access to the report through to your mobile device, and use it to locate anomalies on-site.

Inspection to support warranty claims

Hot spots and activated bypass diodes are indicators of potential module failures. If the modules are within warranty, you can use evidence of these types of failures to support a warranty claim. Simply Drones assists you to identify these issues, as well as provides the documentation necessary for a claim.

Reviewing anomalies

Our full report enables you to review infrared images associated with anomalies identified during site inspection. The IR image shows a higher temperature for the anomalous area or component compared to adjacent areas or components. This is because defects dissipate solar energy as heat rather than converting it to current.
