Photovoltaic Inspection Service
Combined thermal and visual cameraBy integrating thermal imaging with high-resolution visual cameras, we can effectively detect a range of defects and abnormalities in solar panels, including:
Loss of Electrical Yield: Thermal imaging can identify areas of the solar panel that are not performing optimally, which may indicate a loss of electrical yield.
Overheat Connections: Overheating at connections can be a sign of poor electrical conductivity or potential failure, which thermal imaging can highlight.
Failed Bypass Diodes: Bypass diodes that have failed can cause hot spots on the solar panel, and thermal imaging can pinpoint these issues.
Overload and Short Circuits: Thermal imaging can detect areas of the solar panel that are overheating due to overload or short circuits.
Penetration of Moisture: Moisture penetration can lead to corrosion and reduced efficiency, and thermal imaging can reveal the thermal signatures of wet areas.
Failed or Disconnected Modules: Modules that have failed or become disconnected can be identified by the irregular thermal patterns they produce.
Cracked Cells or Glass: Cracks in solar cells or the glass surface can be detected by the temperature variations they cause.
Mismatched Panels with Different Abnormalities: Thermal imaging can help identify panels that are not performing in sync with others, which may be due to a variety of abnormalities.
Loose Contacts and Wiring Faults: Loose contacts and wiring faults can lead to hot spots and reduced efficiency, which thermal imaging can reveal.
Wear and Tear: Over time, solar panels can experience wear and tear that affects their performance, and thermal imaging can detect these gradual changes in thermal patterns.
Efficiency Enhancement and Eco-Friendly TestingThe use of electrically powered drones for thermal inspection is a non-destructive and environmentally friendly testing method, which is up to 16 times faster than handheld thermal instrument inspections. It detects faults early, increasing the efficiency of the solar plant, reducing downtime, extending the lifecycle of the PV system, and lowering the cost of operation and maintenance.
Safety and Risk ManagementThermal inspection ensures safety during the inspection process, minimizing potential risks. Early detection of faults reduces downtime and mitigates operational risks, enhancing overall safety.
Asset Transparency and ReportingThe reports generated from thermal inspection can improve the transparency of solar assets for investors and rating agencies, meeting the requirements of financing and warranties, and enhancing the appearance of the plant.
The detection of solar photovoltaic panels is a relatively time-consuming work, because more pre - and medium-term preparation is needed before the detection, such as daily maintenance data of solar equipment and local climate conditions, which require our customers to provide certain help. We once obtained more useful data in a short time on a photovoltaic inspection project in jinzhou. jinzhou project due to its three-dimensional landform, the investigation of the photovoltaic power station is quite difficult. It takes at least two days to prepare the drone for operation, including on-site setup of the flight app, map app and camera. Drone pilot screening is only a small part of the job, but we also need to measure, evaluate and set up ground control points on the site. The horizontal Angle taken by the thermal imager must be between 60 and 90 degrees and parallel to the vertical reflection of the solar panel. Thermal imagers need to be calibrated for outdoor humidity, atmospheric temperature, distance and emissivity. In order to post process the data more effectively, we need to know the type of solar panel, the average irradiance of the site, the type of photovoltaic system, the total voltage and power output, and the installation Angle of the solar panel. It can be seen that it is a more complicated project to carry out effective status detection of a power plant completely.
