DJI Dock: Unleashing Efficiency in Solar Farm Management

In the vast landscape of solar energy production, solar farms stand as beacons of sustainable power generation. Yet, the efficient management of remote solar farm sites, especially expansive ones, poses significant challenges in terms of manpower and time consumption. Traditionally, conducting regular inspections of solar panels involved dispatching personnel to these remote sites, capturing data manually, processing thermal information, and subsequently analyzing the findings for stakeholders. Recognizing the need for a more streamlined approach, a solar farm operator in Negeri Sembilan, Malaysia has embraced DJI Enterprise’s drone technology, leveraging the autonomous DJI Dock, to revolutionize their workflow. This shift ensures that data collection is regularly updated and adheres to a scheduled routine, optimizing solar panel maintenance and reducing downtime.

The DJI Dock, designed for advanced solar farm inspection, boasts a robust build that ensures enduring performance in challenging environmental conditions. With an IP55 Ingress Protection, the dock is shielded from dust and water, maintaining its functionality even in adverse weather conditions commonly encountered in solar farm settings. Its operational flexibility shines through with an operating temperature ranging from -35℃ to 50℃, enabling effective functioning in diverse climatic conditions, particularly in Malaysia’s tropical climates. The DJI Dock's autonomous operation features include a backup battery with a 5-hour capacity, ensuring continuous operation during power interruptions. The Active Temperature Control not only facilitates fast charging but also ensures optimal drone performance and safety during crucial inspection operations. Additionally, with a remarkable 6-month maintenance interval, the DJI Dock minimizes downtime, providing consistent operational efficiency for solar panel inspections.

The Matrice 30 Thermal, an integral component for DJI Dock, offers advanced features for precise and reliable thermal analysis. With an equivalent focal length of 40 mm, it provides detailed and accurate thermal imaging, ensuring thorough data collection. The high resolution of 640×512 guarantees dynamic thermal imagery, capturing thermal changes in real-time through DJI Flighthub 2. Ensuring measurement accuracy, the thermal imaging camera boasts a ±2°C or ±2%3 accuracy, providing reliable thermal data for in-depth analysis.

In tandem with the Matrice 30 Thermal Imaging Camera, the Cloud Platform Management through FlightHub 2 unlocks the full functionality of the DJI Dock from the cloud. This intuitive and accessible cloud-based platform allows users to schedule missions, create and edit flight routes, and manage collected data seamlessly. This streamlined setup ensures a swift and effective deployment for solar panel inspections.

DJI Dock Autonomous Inspection Workflow

1. Site Inspection: Installing the DJI Dock requires meticulous consideration of several criteria, including the availability of a power outlet, a dedicated LAN internet cable, and a flat surface to accommodate the dock. Ensuring these prerequisites are met guarantees the smooth deployment of the autonomous drone for solar panel inspections.

1. DJI Dock Flight Planning: During the installation of the DJI Dock, comprehensive testing flights are conducted to ensure that the drone can be deployed without interference or restrictions from unnecessary obstacles. This is particularly crucial as it involves beyond-visual line of sight (BVLOS) drone operations.

   
   
   
   

2. GEO Fencing: To prioritize the safety of aerial operations, GEO fencing and task area zoning is implemented, ensuring that the drone operates exclusively within dedicated areas of the solar farm site. This safety measure is accomplished through Geo Zone planning in DJI Flighthub 2.

   
   
   
   

3. Set Mapping Area for Scheduled Flight Missions: Solar farms typically consist of multiple clusters or marked areas. Segmentation is vital for efficient management. By defining specific mapping areas for scheduled flight missions, the solar farm's extensive territory is effectively organized.

   
   
   
   

4. Set Scheduling (Frequency and Flights per Month): Determining the optimal frequency and number of flights per month is a crucial aspect of the workflow. Depending on stakeholder requirements, solar panel inspections can occur daily, with multiple flights per day. The standard frequency, however, is set at twice a month for each area or cluster. This routine ensures regular maintenance and minimizes downtime.

   
   
   
   

5. Dedicated Data Collection in DJI Flighthub 2: DJI Flighthub 2, an all-in-one mission planning platform, facilitates seamless data collection from pre-planning to execution. The thermal data collected is stored in the cloud, providing easy access and enabling cloud mapping capabilities for direct data processing into mapped overlays.

   
   
   
   

6. Annotation, Review, and Report Submission: Post data collection, the ability to review the entire map and drill down into each data point is facilitated through annotation features. This allows for the identification of malfunctioning solar panels and the assessment of their conditions. The information gathered is then reviewed to produce a comprehensive report for stakeholders, streamlining the solar panel maintenance process and ensuring proactive decision-making.
