The cost of photovoltaic power generation is an important reason that restricts the wider application of photovoltaic products. On the module side, there are two main ways to reduce costs, one is to increase the photoelectric conversion efficiency of photovoltaic products, and the other is to reduce the production cost of photovoltaic products. However, many technologies will increase the production cost while increasing the photoelectric conversion efficiency, until the emergence of the multi-bus grid technology, while taking into account the reduction of silver paste consumption and the increase of module power. Since the beginning of this year, Trina Solar, Longi, Canadian Solar, JinkoSolar, GCL and other photovoltaic companies have successively developed 12 busbar module products. Multi-busbar technology has attracted great attention in the industry.
Three years ago, during the follow-up technical route planning, the pilot, after many investigations, used half-cell and multi-busbar MBB as the main follow-up development technical route. The half-cell development equipment is relatively simple, but MBB has very little experience at home and abroad. The development of equipment imposes a technical blockade on the country. Pioneer started from scratch, and through strategic cooperation with Trina Solar, successfully broke through various technical difficulties such as MBB multi-gate ribbon alignment and alignment accuracy, welding temperature uniformity and stability, and realized the first 500MW capacity workshop in China. Mass production.
The leading LDTH2000 multi-bar (MBB) stringer has pioneered the infrared welding of multi-bar cell technology in China, realizing the highest mass production capacity of the domestic multi-bar stringer of 2000 cells/hour, which can be adapted to welding multi-bar cells below 15 bars. And has more than 20 patented technical support. Following the LDTH2000 multi-bar stringer, Pioneer will launch the LDTH2400 multi-bar stringer, which will achieve the highest mass production capacity of 2400 pcs/hour under the premise of ensuring the welding process.
Technical advantages
1. Full-process turnkey technical services can be provided
2. Originally integrated bus bar welding technology on the stringer
3, high compatibility: 4BB~15BB are compatible
4, alignment accuracy: ±0.2mm
5, high-quality welding quality: average welding tension ≥ 1N
Tianhe 12-bar module products have now entered the mass production stage. As of early October, the module output was 12MW, and the actual string yield was greater than 98.5%. This is inseparable from the strong support of the LDTH2000 multi-bar (MBB) stringer welder jointly developed by Pioneer Intelligence and Trina Solar.
Optional "turnkey" value-added services
Wang Yanqing, chairman of Pioneer Intelligent, said that Pioneer has maintained a technological lead among domestic photovoltaic equipment manufacturers for many years. For the multi-bar stringer, although foreign equipment has been developed earlier, its production capacity and welding quality are not good, and the price is expensive. , But there is no domestic experience in the development of such equipment. The pioneer started from scratch and invested a lot of money in the research and development of new equipment. Judging from the mass production of Trina, our products have achieved success. It is foreseeable that the combination of TRW and Pioneer will lead MBB to become a leader in the technical route of various components.
upholds the "innovation" driving concept, pioneering based on the original development and manufacturing of photovoltaic cell module automation equipment, continuous innovation and development, and leading photovoltaic automation equipment to a faster, more efficient and smarter road.
