SNEC site Mingguan n-type battery packaging overall solution, leading the upgrade of component packaging technology From May 24th to 26th, the world's most influential photovoltaic event - SNEC Photovoltaic Exhibition was held in Shanghai. At the scene, International Energy Network visited Mingguan New Materials. 2023 is the year when n-type technology will be fully scaled up. Enterprises have launched n-type products one after another, and hundreds of gigawatts of production capacity are under construction. The entire photovoltaic industry chain is ready for upstream silicon materials, silicon wafers, batteries, modules, and even backplanes, adhesive films, and silver pastes. China's photovoltaic industry is moving towards the n-type era in an all-round way. Then, why does China’s photovoltaic industry rapidly carry out technological iterations, what technical pain points still exist in the n-type era, and how companies face various impacts brought about by technological iterations? I met the relevant person in charge of Mingguan New Materials and listened to him reveal the answers to the above questions. In the n-type era, technology iterations are not limited to batteries The photovoltaic industry is a complete industrial chain. The emergence, development, and further advancement of any technology into the mainstream technology of the industry requires the cooperation of the upstream and downstream of the industrial chain. At the same time, the photovoltaic industry is a very fine-grained industry. Technology upgrades and then technical iterations are completed through bit by bit technological progress, and the process from quantitative change to qualitative change is completed. Just like the current industry hotspot - n-type technology, many people may turn their attention to the field of batteries and modules, focusing on the conversion efficiency of TOPCon or HJT batteries and modules, while ignoring that the improvement of battery and module efficiency is only the final result . In this process, silver paste, adhesive film, and backplane have also made important contributions, and technology upgrades and iterations are also required in the n-type era. According to the person in charge of Mingguan, although the n-type battery technology has many advantages such as high conversion efficiency, high bifaciality, low attenuation, and low temperature coefficient, the special structure of the n-type battery has great impact on the anti-PID performance of packaging materials, Corrosion resistance, water resistance, adhesion and other aspects have more stringent requirements. The packaging materials used in the past for p-type components are not enough to meet the needs of the n-type era. In order to shift the photovoltaic cell module technology from p-type to n-type with higher efficiency, it is necessary to solve the problem of packaging materials, and to have a packaging solution suitable for n-type cell modules. This is a real problem facing th...

550W Photovoltaic Panel Dimensions Photovoltaic panel high efficiency single glass single crystal 550 watts size 2261x1134x35mm. The frame of the photovoltaic panel is made of aluminum alloy, which not only ensures its hardness, but also ensures that it will not rust and rot and is relatively lighter in weight, ensuring its longer service life. On the surface of the photovoltaic panel is a piece of tempered glass with extremely high light transmittance. The more transparent the glass, the higher the power generation efficiency. Therefore, photovoltaic panels have high requirements for the light transmittance of tempered glass. The main cell for power generation is tightly bonded to the tempered glass. Currently, the mainstream photovoltaic cells include monocrystalline silicon, polycrystalline silicon, and thin-film power generation cells. The efficiency is good, but the high cost caused him not to be widely promoted. How many kilograms does a 650 double glass solar photovoltaic panel weigh? The weight of 650 double-glass solar photovoltaic panels is generally about 20 kg, and the actual weight varies with manufacturers and models.

French start-up Holosolis, founded by innovation group EIT InnoEnergy, has announced plans to build a 5GW solar module factory in France. Other partners in the project include IDEC Group, a real estate company specializing in the rooftop market, and TSE, a French solar developer specializing in agricultural photovoltaics. According to the plan, it is expected that commercial production will start in 2025 and reach full capacity in 2027. By then, the annual module production capacity will reach 5GW. The factory is located in Sarreguemine in northeastern France, close to the German border, and plans to employ 1,700 people. Modules produced at the factory will focus on three markets: residential rooftops, industrial and commercial rooftops, and agricultural photovoltaics, though the technology used was not disclosed. PV Tech contacted EIT InnoEnergy to find out which technology the new plant will use. Commenting on the announcement, Holosolis CEO Jan Jacob Boom-Wichers said: "We will produce the most energy-efficient modules, using the latest photovoltaic technology, with the lowest carbon footprint and the highest social standards. Economies of scale and production line automation can bring at competitive costs that rival the global giants in the industry." It is the latest in a string of new solar module factories announced in Europe since the European Commission unveiled its Green Deal industry plan in February. The Green Industry Deals scheme aims to expand in-house capacity for net-zero technologies in the EU. Upstream activity in France has been in flux for the past few months. Startup Carbon plans to build a 5GW cell and 3.5GW module plant in Marseille, southern France, which is expected to be operational by the end of 2025. Solar company Reden Solar plans to increase its module production capacity in France from 65MW to 200MW by 2024. Furthermore, EIT InnoEnergy's project is part of an initiative put forward by the European Solar Photovoltaic Industry Alliance (ESIA), for which EIT has been appointed as its secretariat. ESIA's goal is to reach 30GW of production capacity across the entire value chain in Europe by 2025.
