Global solar giant LONGi has launched its new home photovoltaic (PV) building green power solution. Named LONGi eHome, the product encompasses rooftop solar PV, electrical systems, energy management software, and full-process services, offering a one-stop PV solution for households.
According to LONGi, the LONGi eHome differentiates itself from traditional home PV systems through innovations in installation design, smart modules, and energy storage inverters. For instance, its BIPV solar tiles come in various colors and sizes, allowing seamless integration into buildings. The intelligent storage-inverter unit utilizes AI technology to optimize household energy management, enabling real-time power monitoring. Additionally, LONGi’s patented modular installation method simplifies the PV installation process into just 3 steps, lowering technical barriers and making home PV applications more accessible.
Recently, LONGi’s Hi-MO 9 module received the PV Pioneer Cutting-Edge Technology Product Certification from CGC (see China Solar PV News Snippets).
Guohua Energy Investment, a subsidiary of the leading Chinese energy developer CHN Energy, has announced the results of the first batch of its centralized solar PV module procurement for 2025. Announced for a total capacity of 586.24 MW, the auction called for n-type monocrystalline bifacial dual-glass modules with a 620 Wp power rating and above, and module deliveries to be completed by the end of December 2025. Tongwei and JA Solar have been shortlisted as the first and second preferred bidders, with winning prices of RMB 0.699/W ($0.097/W) and RMB 0.705/W ($0.097/W), respectively.
TOPCon cell manufacturer Yingfa Group has introduced its latest n-type TOPCon 210R 2.0 cell, featuring the company's TOPCon 2.0+ technology. This advanced cell incorporates multiple cutting-edge processes, including poly multilayer film technology and short-time variable temperature annealing technology. The manufacturer claims the new TOPCon 210R 2.0 cell has achieved a maximum conversion efficiency of 27.02%, while the highest module power output reaches 730 W.
Yingfa Group, along with LONGi and Sichuan Wuliangye New Energy Investment, recently established a joint venture focused on the research and manufacturing of BC solar cells (see China Solar PV News Snippets).
Solar module and backsheet manufacturer Jolywood, in collaboration with multiple industry enterprises and research institutions, has officially implemented the group standard "Weather Resistance Testing Method for Steel Frame Materials Used in Solar PV Modules." This standard provides a unified and standardized method for testing the weather resistance of steel frame materials.
Targeting PV module frames utilizing zinc-aluminum-magnesium alloy coating technology, the standard includes 9 comprehensive weather resistance tests, covering neutral salt spray, C6 salt spray, C7/C8 cyclic salt spray, sand dust, ammonia resistance, UV damp heat, UV damp freeze, damp heat, and UV thermal cycling damp freeze. These tests simulate extreme global climate conditions to ensure the structural safety of modules throughout their lifecycle.
Solar quartz crucible manufacturer Ojing has announced adjustments to its previously planned PV quartz crucible project, reallocating part of its raised funds to semiconductor quartz crucible production. The company had originally allocated RMB 252.88 million ($34.94 million) for its Ningxia Phase II PV quartz crucible project. However, due to increased competition and profit pressures in the PV industry, the company has decided to redirect RMB 100.41 million ($13.87 million) from this project to invest in semiconductor quartz crucible production, aiming to enhance capital efficiency. The new project will be implemented in Hohhot, Inner Mongolia, and upon completion, the company is expected to achieve an annual production capacity of 26,000 semiconductor quartz crucibles. Meanwhile, the originally planned Ningxia Phase II PV quartz crucible project has not yet commenced.
