On-site Drone Inspection
We are a legally registered entity with the Civil Aviation Administration and have extensive experience in securing operational approvals for no-fly zones. Before each aerial inspection, we obtain authorization from the relevant authorities and strictly adhere to their regulations. Customers must complete a PV plant information form in advance to facilitate preparation. On the day of the inspection, a certified drone operator arrives equipped with professional-grade UAV systems. The operation is conducted under specific conditions, including adequate solar radiation, an active PV plant, and clean module surfaces, since excessive soiling can create hot spots that may interfere with defect analysis. Our drone equipment is covered by UAV liability insurance, providing up to NTD 3 million for accidental bodily injury and NTD 1 million for accidental property damage. Within one week of the inspection, clients can access results and download reports via the IRUAV APP.
Advanced AI Analysis
With over 150MW of experience in PV plant inspections, we have amassed extensive IR and RGB data from Taiwan’s PV systems. Our team has conducted the industry's most detailed classification of thermal defects, building a comprehensive database to identify abnormalities that impact system performance and safety. Currently, our AI model achieves an average accuracy rate exceeding 90% and has been seamlessly integrated into IRUAV Analysis software, effectively applying AI technology to aerial inspection analysis. We remain committed to continuously refining and enhancing our AI model to deliver the highest-quality aerial inspection results for our clients.
Cloud Visualization System
To help clients efficiently manage multiple PV plants, we have developed a cloud-based visualization system for storing and presenting aerial inspection results. This system automatically generates standardized reports, ensuring consistency and ease of interpretation. Clients can access the visualization system via the IRUAV APP on both computers and mobile devices. The app features a search function for quickly locating specific PV plants, while abnormalities are clearly highlighted on modules within the orthophoto—allowing maintenance teams to identify and address issues with precision. Additionally, the system includes a comparison feature for previous inspection data, serving as a "health check" for PV plants. Maintenance logs track team actions, ensuring thorough documentation and streamlined operations.
Module 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 performance measurement, the International Electrotechnical Commission (IEC) has established Standard Test Conditions (STC), defining 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 results. If a PV system’s power generation is lower than expected despite no abnormalities detected through aerial inspection, selected modules can be sent to a laboratory for STC power testing. This process helps determine whether systematic degradation, such as LeTID, has occurred.
Module EL Testing
With a large number of PV modules installed outdoors, detecting internal damage with the naked eye is challenging. If aerial inspections reveal a significant number of non-shading hot spots, selected PV modules can undergo electroluminescence (EL) testing in a laboratory for further evaluation. EL testing utilizes the electroluminescence properties of PV modules. When a specific current is applied, defects become visible, where 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 and defect patterns, the root cause of abnormalities can be identified. If the issue originates from module quality, a laboratory report provides clear validation, making quality concerns easier to recognize and address.
Module Insulation Testing
Solar power system voltage is generally as high as 1000~1500V, and this high voltage exists in the internal conductors of the system. If the solar module insulating materials, such as backsheets and EVAs, deteriorate, they may cause leakage, resulting in inverter tripping or inductance. Laboratory dry and wet insulation current testing can be utilized to determine the dielectric strength of solar module insulation materials when subjected to high voltages. The test conditions are 1000V plus 2 times the system voltage into the junction box connector and aluminum frame. If the calculated insulation resistance after the insulation test is less than 40 MΩ/meter squared, the insulation function or material of the solar module may have deteriorated.
Cybersecurity Certified Drone
Taiwan has been actively advancing its drone industry in recent years through government initiatives. The domestic supply chain and national team are gradually taking shape, alongside the establishment of a cybersecurity certification system. Local manufacturers have independently developed flight control and ground station systems, as well as RTK modules and three-spectrum cameras—including thermal imaging, visible light, and ranging—to support critical inspection functions. In addition to developing its own drone and telescopic pole solutions, the platform closely tracks Taiwan's drone industry trends. It actively evaluates mass-producible, cybersecurity-certified drone equipment for integration into operational tools. These drones are expected to be deployed for government agencies' PV system inspections, with preliminary results anticipated by 2026.
DJI Enterprise Drones
From drone flight control systems and aerial vehicle design to multi-axis gimbals and high-resolution image transmission, DJI's products are widely utilized across industries such as aerial photography, filmmaking, agriculture, firefighting, rescue operations, energy, and remote sensing surveying. Our platform has successfully integrated DJI enterprise drones—including the Mavic 3T, Matrice 4T, and Matrice 350 RTK + H20T—into our aerial inspection services. To enhance real-time data analysis, we developed the IRUAV Pilot software, allowing on-site inspection data verification before seamless integration into our platform for further analysis. Additionally, we offer sales of these drones and provide official after-sales services to ensure optimal performance and support for our clients.
Inspection Practice Course
When implementing data-driven maintenance management, clients can begin with the 【Option A】 package, which includes aerial inspections during the initial stages. After evaluation, they can transition to 【Option B】 for in-depth analysis and reporting. Before adopting 【Option B】, clients must complete a hands-on inspection training course based on the IEC 62446-3 technical document. This course integrates years of industry expertise to train clients on operating platform-compatible drones for efficient, high-accuracy aerial inspections. For clients already equipped with compatible drones and certified drone pilots, combining the course with a subscription-based 【Option B】 analysis and reporting service enables them to rapidly achieve professional-grade aerial inspection capabilities.
