Zhuhai Gree Electric Appliances Co., Ltd. and Guochuang Energy Internet Innovation Center (Guangdong) Co., Ltd. have applied for a patent titled “Photovoltaic Thermal System and Control Method,” according to information from the National Intellectual Property Administration. The patent application, published under the number CN 119617666 A, was submitted on December 2024.
The patent summary indicates that the application relates to a photovoltaic thermal system and its control method. This system includes a heat collection module designed for thermal energy collection, featuring photovoltaic thermal panels. It also includes a water heat module that exchanges heat with the collection module to produce hot water, as well as a data acquisition module that collects photovoltaic state data from the panels. Additionally, the system features a cleaning module that connects hot water to the photovoltaic thermal panels when cleaning is necessary, based on the photovoltaic state data. This innovative approach effectively removes accumulated dust and contaminants from the panels, enhancing their photovoltaic conversion efficiency.
By minimizing wear and corrosion on the panel surfaces, the system extends the lifespan of the photovoltaic thermal panels. Moreover, the automated cleaning feature reduces the need for manual intervention, thereby lowering maintenance costs.
