The high temperature is abnormal these days. I believe many people hide in the air-conditioned room and don't want to come out. However, for the photovoltaic industry, this period of time is the peak period of photovoltaic module power generation. Coupled with the impact of high temperature, equipment maintenance has also become one of the main tasks.

The previous maintenance work was very laborious, and for large projects, it mainly relied on "human sea tactics" to ensure the normal operation of the system. However, with the popularization of UAV technology for civilian use, the workload has been alleviated to a certain extent. It happens to be China's Army Day today. Let's talk about how to improve the efficiency of photovoltaic equipment, a technology that has been transformed from military use to civil use.

Military to civilian technology

The controllable unmanned aerial vehicle was first launched under the radio control of the Royal Air Force arpaven Air Force Base in 1917, and then developed at a high speed during the two world wars and the cold war. However, miniaturization and civilian use have only occurred in the past three decades.

By 2022, the four axis aircraft UAV has become the most widely used UAV in the civil field, and has been effectively used in many industries, among which the most used is undoubtedly the function of surveying through the camera.

Application of fully automatic inspection

Due to the wide flight distance, UAV is used in aerial survey, information collection and other work. The representative ones are agricultural field patrol, aerial photography and mapping, oil exploration, etc. Among them, the function of equipment inspection naturally exists, and it is a more refined choice for the photovoltaic industry.

Usually, the photovoltaic power station will be set in the outdoor or water with high altitude and abundant light. It is very difficult to commute during manual inspection, and the terrain is complex. If unmanned aerial vehicles are used for patrol inspection, the difficulty can be greatly reduced and the efficiency can be improved.

More efficient and fast detection

Recently, due to the preferential policies of various countries towards the new energy industry, the UAV industry began to invest resources in photovoltaic management. Fully automated unmanned inspection appeared immediately, and the photovoltaic system also ushered in mechanized management.

Taking a 40MW large-scale ground photovoltaic power station as an example, it takes 8-10 days for two inspectors to inspect all components on foot. The inspection efficiency is extremely low and it is difficult to ensure the inspection quality.

However, with the addition of UAV, the trained helmsman can manually operate the UAV patrol, and the working time and difficulty have been greatly reduced.

Through the thermal imaging, refractive index and other data collected by aerial photography, the problem location can be quickly detected, and the troubleshooting and maintenance can be carried out in a timely manner, making the detection more comprehensive and accurate. It is expected that the application of this kind of system will be very common in large projects in the future.

At the same time, unmanned aerial vehicles in patrol inspection consume electricity, while solar power generation just meets the energy requirements and can achieve self-sufficiency. While improving efficiency, it also meets the requirements of 0 CO2.

Better quality

Through the unmanned inspection, the management of photovoltaic system is developing towards refined operation. Therefore, every place of power station management should pay more attention to quality and efficiency.

Even if the inspection is more efficient, if the product itself is of insufficient quality, frequent maintenance will increase the operating cost. Good products can reduce the number of maintenance and the probability of operation problems. For this reason, this intelligent inverter is recommended here

In terms of after-sales service, SUNPRO POWER’s inverter has 5-year warranty and 15 year performance guarantee. If the buyer encounters problems during use, it is a strong guarantee.

*****************************

With the advent of the era of energy transformation, the demand for new energy represented by photovoltaic has gradually increased sharply. The expansion of scale will inevitably increase the difficulty of management, and the demand for mechanical automation has become the next direction.

If you are preparing to expand the scale or plan to carry out a large-scale project, remember to consider the subsequent operation problems in advance, because this will affct the actual output of the project.
