Drone Photovoltaic Inspection

1.Drone Photovoltaic Inspection Product Introduction

Drone Photovoltaic Inspection refers to the automatic inspection of photovoltaic panels using unmanned aerial vehicles (UAV) equipped with cameras and infrared thermal imagers.The photovoltaic drone EL detector is used for the quality inspection of EL internal defects of array components in photovoltaic power stations. This system can quickly and efficiently complete the quality inspection of photovoltaic power stations, and can switch between photo mode and video mode for third-party operation and maintenance quality inspection. It can switch between multiple modes of detection with full automatic focus, making it the preferred equipment for power station inspection and operation and maintenance inspection.

The equipment uses the (M300 RTK) drone, which has a single flight time of up to 55 minutes, providing a stable and reliable high-performance flight platform for third-party industry drone applications. The 3-hour MW-level photovoltaic power station EL hidden crack inspection allows workers to say goodbye to tedious and repetitive low-value labor, greatly improving work efficiency. With the help of drone technology, the electric knife work automation process can be realized, effectively reducing operation and maintenance costs. At the same time, it can be used as an agent for personnel to perform high-altitude and high-risk environment operations, making EL detection safer.

5. Drone Photovoltaic Inspection Product Advantages

1. Advantages of drones

M300 PTK is safer and more reliable with long-lasting flight

The device uses the top drone (M300). As a top drone manufacturer, the M300 RTK has higher flight stability and reliability. The lightweight design of the M300 can carry an all-weather large-load moving knife system with a long battery life of up to 55 minutes, and relies on the new OcuSync industry version of the image transmission system, which brings a control distance of up to 15 kilometers and three-channel 1080P high-definition image transmission. The drone is equipped with 2.4/5.8GHz dual-channel communication, which can automatically switch to the best channel in real time during the inspection process. It can still effectively resist interference in complex environments. It is equipped with AES-256 image transmission encryption technology to always ensure data transmission security, support LTE backup links, and further improve the reliability of image transmission. The entire system has higher performance stability.

Efficient and professional all-in-one aerial photography solution

The M300 drone adopts a modular design. The efficient moving blade system integrates dust and rain protection, active heat dissipation functions, and provides a maximum wind resistance of 15 meters per second. After being equipped with a drone EL detection gimbal camera, it can provide up to 50 minutes of endurance detection and 45 minutes of hovering monitoring. It only takes 40 minutes to fully charge a single battery, and 3 batteries can achieve uninterrupted EL inspection and testing of photovoltaic power stations.

2. Advantages of EL inspection

15KM GPS inspection flight

The device provides ultra-long battery life and long-distance real-time battery life detection with a maximum range of 15 kilometers. At the same time, the high-precision GPS route planning function, combined with a fully automatic optical zoom camera, makes unmanned intelligent inspection of photovoltaic power stations possible.

3. High-power imported EL power string power supply

EL string power supply is the core equipment of the whole system. It not only determines the imaging clarity but is also an indispensable part of efficient EL full inspection.

The power system of this equipment can perform power-on tests on multiple strings of EL at the inverter/combiner box. The power supply has a built-in programmable temperature control system to ensure that the temperature of the power supply is below the safe range of 50°C for long-term use. At the same time, the digital control panel greatly reduces the risk of human contact and can better ensure the safe use of operators.

4. Advantages of EL Camera

50Hz high frequency imaging

The EL camera on this device uses a German high-frequency InGaAs infrared chip and has a more excellent infrared sensor, which provides hardware guarantee for the clear image quality of EL detection. The high-frequency imaging technology can provide clear and thorough dynamic videos and aerial photos of internal defects of photovoltaic modules when the drone is flying.

Full-time auto focus in low light

An accurate focusing system is the core requirement for EL imaging, and the clarity of the image is determined by it. The EL camera of this device relies on the independently developed infrared lock relative focus system, which enables the device to perform real-time fully automatic zooming during the drone inspection process, freeing the drone EL aerial photography detection from the troubles of follow-focus devices and fixed-point flight.

5. Software advantages

Video processing software

For drone video inspection mode, EL cameras can save a variety of optional video formats, and the software can enhance the video quality and extract single-frame images to facilitate user report compilation and analysis

Image processing software

For drones in hovering photography mode, the EL camera can take multiple continuous shots and save multiple EL images at the same time. The software can be used to synthesize and process them to generate clearer images of internal defects in components.

Cloud management system (optional)

Our online cloud system has the functions of image storage, data storage, power station operation and maintenance data management, power station inspection report generation and export, automatic identification, power station information management, power generation evaluation and PR system efficiency value calculation.

Automatic defect recognition (optional)

The EL automatic identification software relies on the online cloud processing system. Users can independently conduct Ai identification learning and generate exclusive identification modules. They can also select existing identification modules to identify internal defects of photovoltaic modules. The identification types include broken pieces, fragments, hidden cracks, short circuits, attenuation, etc.
