In the transformation and upgrading of solar energy enterprises, we must first recognize the direction of product upgrade. At present, the all-glass compact in-line and non-pressure-bearing solar water heaters on the market can no longer meet the increasing demand of consumers. The transformation and upgrading of the solar energy industry to new energy cannot be completed by a single product. A single product of a solar water heater should be upgraded to a high-end, intelligent, all-weather, and healthy water. More importantly, it is necessary to develop and produce split and pressure-free products that can be installed on roofs, balconies and buildings, in addition to vacuum tubes and flat panels. In short, the development of diversified products is the top priority of transformation and upgrading.
Fan Chaohong, chairman of the Rays Group, said that the transformation and upgrading of enterprises is an inevitable law of the market economy. Among them, technological innovation is the key. Only by hard work and internal strength can we find our own position in a fully competitive market and realize the long-term development of the enterprise. Only by building leading energy-saving and environmentally-friendly high-tech products can we ensure that the company is in a leading position. In 2010, Jiangsu Rays Group, which is well-known for its technological innovation, has successively developed the first domestic variable frequency cooker, frequency conversion range hood, frequency conversion gas water heater and other products. It has pioneered the development of concealed forced circulation balcony wall-mounted solar energy, multi-energy water tanks and other new energy sources. product. In the whole year, Ray Group applied for and obtained 54 patents, and the output value of new products exceeded 28%. It has stepped out of the scientific road of accelerating enterprise transformation and upgrading with technological innovation.
Fan Chaohong said that on the basis of independent innovation, enterprises attach great importance to cooperation in production, education and research, and let product research take a high level. In 2010, Ray Group invested a total of more than 20 million yuan in research and development and technological transformation, and successively launched a series of high, fine and new products. At present, it has established long-term cooperation in production, study and research with Tongji University, Shanghai Jiaotong University, Nanjing University of Aeronautics and Astronautics, Beijing Machinery Automation Research Institute, Yunnan Normal University and many other research institutes, and has mastered many industry leading technologies and key technologies. If enterprises want first-class benefits, first-class management, and first-class products, they must first have first-class talents. Talents are the most flexible, creative, and value-added elements. Active and effective incentives have spurred the enthusiasm of talents, realized the simultaneous development of talent development and enterprise development, and created a young and middle-aged scientific and technological talent "iron army", which greatly accelerated the healthy development of enterprises.
Wu Zhenyi, president of Tsinghua Sunshine, said that 2011 is the transformation and upgrading of Tsinghua Sunshine. The company will pay more attention to product and equipment innovation and pay more attention to brand building. Going to the countryside, going to the city, going to the sea, and listing have become the four steps of the company's transformation and upgrading. We must strive for survival in the midst of change and seek development in the midst of change.
1. Going to the countryside. The more refined the market, the more fierce the competition is. The more unskilled SMEs and the lack of innovative connotation of the brand-name enterprises, the more difficult it is to stand and survive, the more powerful the large-scale brands will be able to break through and develop. This has greatly accelerated the reshuffle speed of solar companies, which is beneficial to Tsinghua Sunshine. According to statistics, it is estimated that by 2020, the consumption of solar water heaters in the rural market will reach 1.7-180 million square meters, accounting for about 60% of the total consumption. Therefore, in 2011, the rural market of solar water heaters was still singing and the flags were flying. Under this general situation, Tsinghua Sunshine should seize the opportunity, seize the opportunity, strengthen the construction of the tertiary sales network in the rural market, increase the sales of products, continue to strengthen the rural market, and continue to provide marketable solutions for the rural market. product.
2. Enter the city. In 2011, Tsinghua Sunshine's “going into the city†strategy mainly included two categories: one was to lock the urban residents' market, and the other was to rural urbanization. In market development and product development, it is necessary to fully consider different levels of consumption and different environmental needs. In order to meet the needs of the urban market, the products and prices have been adjusted. After entering the city, the products must adhere to the advantages of “high quality, low cost and differentiation†and give back to our consumers. In order to meet the needs of the urbanization market, we have continuously improved on the products and made corresponding adjustments in the sales policy. Facing the new situation in the domestic and international markets, the company has made a comprehensive deployment in marketing. In 2011, the company will implement a new marketing mechanism. The domestic market is divided into 8 regions. In addition, there are four business divisions: photovoltaic, overseas, heat pump, heat collecting tubes and equipment. All of them have a business department mechanism, and each business unit is equipped with certain The number of engineers and technicians has increased the support for agents and customers.
Bi Directions Thyristor (Triac) is equivalent to the antiparallel connection of two unidirectional thyristors, but only one control pole.
Bidirectional thyristors are made of N-P-N-P-N five-layer semiconductor materials, and three electrodes are also derived from the outside. Its structure is shown in the figure. Bi-directional thyristor volt-ampere characteristic curve Since the forward and reverse characteristics of the bidirectional thyristor are symmetrical, it can be turned on in any direction and is an ideal AC switching device.
