Core Viewpoint - Gree Electric's introduction of the "zero electricity cost" air conditioning system has garnered significant attention, addressing consumer concerns about high electricity bills and potentially revolutionizing the air conditioning market [2][4][13]. Group 1: Product Innovation - Gree's "zero electricity cost" air conditioning system utilizes photovoltaic direct drive technology, allowing it to operate independently of the grid and significantly reduce electricity expenses for households [5][13]. - The system integrates solar power generation, energy storage, and air conditioning technology, achieving a high energy utilization rate of 99% by eliminating the need for traditional inverters [13][15]. - Gree claims that in sunny regions, the system can save approximately 4,000 kWh of electricity annually, equivalent to over half a year's electricity costs for an average household [15]. Group 2: Market Competition - The competitive landscape has intensified between Gree and Xiaomi, with both companies engaging in public disputes over market share and product quality [6][12]. - Xiaomi's rapid growth in air conditioning sales, with over 5.4 million units shipped in the first half of 2025 and a year-on-year growth rate exceeding 60%, has put pressure on Gree [12]. - Gree's market share remains strong at 29.42%, but the close competition in online sales, where Gree's share is 17.66% compared to Xiaomi's 15.92%, indicates a tightening market [12]. Group 3: Technological Advancements - Gree has made significant strides in research and development, with a reported R&D expenditure of 7.14 billion yuan in 2024, reflecting a 1.9% year-on-year increase despite overall revenue decline [17]. - The company has filed nearly 140,000 patents, including over 70,000 invention patents, establishing a strong foundation for its innovative products [18]. - Gree's breakthroughs in magnetic levitation technology for large central air conditioning systems could save approximately 20.48 billion yuan in electricity costs annually if adopted by 30% of public buildings nationwide [17]. Group 4: Environmental Impact - The "zero electricity cost" air conditioning system is expected to contribute to significant carbon reduction, with one system's annual carbon offset equivalent to 400 million trees [15]. - Gree's technology aligns with global sustainability goals, promoting a shift from energy-consuming products to energy-efficient systems, thereby enhancing China's position in the green technology sector [21].
