Good news! Qingtian Technology's automatic cleaning robot for solar photovoltaic modules has been granted another national invention patent.
In June 2023, an automatic cleaning robot for solar photovoltaic modules, designed by the R&D team of Qingtian Technology, was granted a national invention patent (patent number: ZL 2022 1 0505675.6). The successful development of the robot will complement the operation and maintenance of photovoltaic power plants, ensuring high-efficiency power generation year-round, reducing cleaning costs, and increasing customers' photovoltaic revenue.
Qingtian Technology's photovoltaic cleaning robot can customize cleaning methods according to different pollution sources in the power plant. Its concealed water tank design, high-speed rotating brush, and integrated rubber strip design ensure that the robot can remove 99% of contaminants from the photovoltaic panel surface through dry sweeping or wet brushing. The entire machine is IP65 waterproof, with a stable body structure and reliable gear propulsion mechanism, enabling it to adapt to various operating conditions and possessing good obstacle-crossing capabilities.
Based on field tests at multiple distributed photovoltaic power stations, the Sunny Day Intelligent Photovoltaic Cleaning Robot can significantly improve the power generation conversion efficiency of the power station. Depending on the project scenario and pollution level, the actual efficiency improvement can reach 8% to 30%. It is currently operating stably in more than 20 projects.
To date, all of Qingtian Technology's independently developed intelligent photovoltaic cleaning robots can operate fully automatically, starting and stopping automatically daily according to remote commands. They also feature real-time background monitoring, remote control, and firmware OTA upgrades. Equipped with photovoltaic module power supply, a high-efficiency MPPT control module, and a BMS battery system, the equipment receives a stable power supply.
In the future, Qingtian Technology will continue to promote the development of intelligent and efficient photovoltaic power generation systems, the research and development of new processes and technologies for related products, and the innovation of comprehensive technologies such as intelligent operation and maintenance systems and multi-energy integration, "taking independent innovation as the main body and industry-university-research cooperation as the foundation". This will form a close integration of technology with production and market promotion, enhance the company's core competitiveness, and achieve steady growth in the company's economic benefits.
