On-site Drone Inspection
We are a legally registered entity with the Civil Aviation Administration and have experience in applying for operations in no-fly zones. Before each operation, we obtain approval from the relevant authorities and comply with their instructions. Customers are required to fill out a PV plant information form in advance. On the day of the aerial inspection, a certified drone operator will arrive with professional equipment. The operation is carried out under specific conditions: sufficient solar radiation, PV plant under operation and clean module surfaces, as heavy soiling may cause hot spots that interfere with the analysis of other defects. The drone equipment is covered by UAV liability insurance, with a maximum coverage of NTD 3 million for accidental bodily injury and NTD 1 million for accidental property damage. Within one week after inspection, clients can through the IRUAV APP to view results and download reports.
Advanced AI analysis
With over 120MW of experience in PV plants inspections, we have collected a vast amount of IR and RGB data from Taiwan’s PV systems. Our team has conducted the industry's most detailed classification of thermal defects and established a comprehensive database to identify abnormalities affecting system performance and safety. Currently, our AI model achieves an average accuracy rate of over 90% and has been seamlessly integrated into the IRUAV Analysis software, successfully applying AI technology to aerial inspection analysis. We are committed to continuously refining and utilizing AI model to provide clients with the highest-quality aerial inspection results.
Cloud Visualization Service
To help clients efficiently manage multiple PV plants, we have developed a cloud visualization system designed to store and present aerial inspection results. This system automatically generates reports in a standardized format, ensuring consistency and ease of understanding. Clients can access the cloud visualization system via the IRUAV APP, available on both computers and mobile devices. The app features a search function, enabling clients to quickly locate specific PV plants. Additionally, abnormality are clearly marked on the modules in the orthophoto, allowing maintenance team to swiftly identify and address anomalies with precision. The system also offers a comparison feature for previous inspection data, functioning like a health check for PV plants. Maintenance logs record maintenance team actions, supporting supervisor's review and data-driven maintenance management function.
STC Power Testing
The output power of PV modules is highly sensitive to temperature fluctuations, varying by approximately 0.4–0.5% per 1°C change. To ensure precise measurement of PV module performance, the International Electrotechnical Commission (IEC) has established Standard Test Conditions (STC), which define module power ratings at 25°C, 1,000W/m² illumination, and the AM1.5 standard spectrum. Laboratory testing under these conditions provides consistent and reliable measurements. If a PV system’s power generation lower than expected despite no abnormality detected through aerial inspection, modules can be sent to a laboratory for STC power testing. This process helps confirm whether systematic degradation has occurred ( For example, LeTID).
Module EL Testing
With a large number of PV modules installed outdoors, checking PV module's internal damage with the naked eye is challenging. If aerial inspections reveal a significant number of non-shading hot spots, PV modules can be sent to perform electroluminescence (EL) testing in a laboratory for further evaluation. EL testing leverages the electroluminescence properties of PV modules. When a specific current is injected, defects become apparent, the more defects present, the weaker the luminous intensity. This process effectively uncovers micro-cracks, disconnections, and other hidden issues. Additionally, by analyzing EL data defect patterns, the underlying cause of abnormalities can be determined. If the issue stems from module quality, a laboratory report provides clear validation, making recognition of quality concerns more straightforward.
Module Insulation Testing
The voltage of PV plants is generally as high as 1000~1500V, and this high voltage exists in the conductors within the system. If the insulation materials of PV modules, such as backsheet or EVA has aging issue, it may cause leakage, inverter shutdown or personnel to be inducted. In such situation, laboratory's wet and dry insulation current measurements can be used to confirm the dielectric strength of the PV module when withstanding high voltage. The test conditions are 1000V plus 2 times the system voltage introduced into the junction box connector and aluminum frame. If the insulation resistance calculated is less than 40 MΩ/m2 , the insulation function or materials of the PV module may have deteriorated.
Cybersecurity Certified Drone
In recent years, Taiwan, with strong government support, has been actively developing its drone industry. A local supply chain and a national team are steadily taking shape, while a cybersecurity certification system is being established. Domestic manufacturers have independently developed flight control and ground station systems, adopting Qualcomm's Flight RB5 5G Platform to create a 4G/5G network control and fleet management framework. In addition to self-developed drone and telescopic pole solutions, we closely watch the evolution of Taiwan's drone industry. It actively assesses mass-production and cybersecurity-certified drone equipment to incorporate as operational tools for the platform. Results are expected by 2026.
Distributor of DJI Enterprise Drones
From drone flight control systems to aerial photography vehicle design, multi-axis gimbals, and high-resolution image transmission, DJI's products are widely used in fields such as aerial photography, filmmaking, agriculture, real estate, journalism, firefighting, rescue operations, energy, and remote sensing surveying. Our platform has successfully integrated their enterprise drones, such as DJI Mavic 3T, Matrice 4T and Matrice 350 RTK + H20T into our aerial inspections. We also developed the IRUAV Pilot software to check aerial inspection data on-site, which is then imported into the platform for analysis. Furthermore, we sell DJI enterprise drones and provide official after-sales services.
Inspection Practice Course
When clients implement data-driven maintenance management, they can start with Option A: Package with aerial inspection and later apply Option B: Analysis and reporting only . Before adoption of Option B, clients must complete the inspection practice course. This course is based on the IEC 62446-3 technical document and combines years of inspection expertise to teach clients how to operate platform-compatible drones for efficient and highly accurate aerial inspections. For clients who already have compatible drones and certifications, combining the course with a subscription-based analysis and reporting only service allows them to quickly gain professional-grade aerial inspection capabilities, which enhances their PV systems maintenance efficiency and reduces costs.
