On July 15, Beijing Energy International’s independently authored research paper, titled “Research on Self-Cleaning Technology for Photovoltaic Modules Based on a Multidisciplinary Collaborative Innovation System”, was successfully selected for the 25th Conference of the Electric Power Supply Industry (CEPSI 2025) Call for Papers. This marks the first time that a research paper from Beijing Energy Holding (BEH) has been accepted by this prestigious international conference, signifying global recognition of BEH’s self-cleaning photovoltaic technology.
The paper focuses on innovation in PV module self-cleaning technologies and proposes a forward-looking and practical multidisciplinary collaborative innovation approach. It covers multiple technological breakthroughs, including surface and interface engineering of materials, intelligent electrostatic dust removal, high-efficiency aerodynamic cleaning, and surface cleanliness detection. These innovations significantly enhance the overall efficiency, environmental adaptability, and intelligence of PV module cleaning systems. Beijing Energy International has applied this technology to its independently developed “Intelligent and Efficient Cleaning Robot for Photovoltaic Modules” project, which has been successfully implemented in two self-owned PV projects in Ningxia and Jiangxi—regions with distinct differences between north and south China. Rigorous experimental validation has demonstrated that the PV module cleaning system maintains excellent performance even under extreme conditions such as low and high temperatures and sandstorms, providing strong technological support for the high-quality development of the new energy industry.
Looking ahead, the company will actively participate in the subsequent paper presentation and evaluation phases. Meanwhile, the company will continue to adhere to its strategic vision of “focusing on core business, deploying nationwide, and expanding globally,” deepen collaboration and exchanges with international peers, strengthen its global energy cooperation network, and strive to elevate China’s voice and influence in the international power sector, contributing further to the global reputation and visibility of Chinese power enterprises.
