Recently, Wang Sicheng, a researcher at the Energy Research Institute of the National Development and Reform Commission, revealed that the "Technical Specifications for Photovoltaic Power Plant Performance Testing and Quality Assessment (Draft for Soliciting Opinions)" will be issued at the end of September, focusing on the performance ratio of photovoltaic power plants to provide basis for future power plant transactions and bank loans.
The die casting process involves the use of a furnace, metal, die casting machine, and die.

Xu Hailiang, Director of PV Product Department of Ding UV Southern Germany, believes that the introduction of the standards for distributed power plants is of positive significance to the industry. It means that the distributed project will have a complete and comprehensive evaluation process, which will have a great regulatory effect on the market. . And the assessment can give investors a fair and reasonable analysis of investment returns. The domestic distributed power plant certification has just started. Zhang Xucheng, deputy general manager of the Sun Power Power Plant Division, said that in the European market, when photovoltaic power plant investors are looking for banks to solve financing problems, banks will require third-party certification to prove that the quality of power plants can be achieved. Expected rate of return before agreeing to the loan. Sunlight Power's reason for introducing Ding UV certification is to lead the standardization of distributed photovoltaic power plants in China and not to make the market worse.
Xu Hailiang introduced that Ding UV has more than 4Gw power plant acceptance and audit experience in the world, and has started to do distributed project certification since 2009. Xu Hailiang explained to reporters that the quality certification of distributed power plants mainly assesses the following aspects: quality conformity assessment, design assessment, power generation, and yield assessment of key equipment used in the project, safety assessment, testing, and transportation of the project itself. Dimension requirements.
Zhang Xucheng believes that through the cooperation with TUV, Sunlight Power can learn from TUV, and in the future, it will summarize its own power plant construction specifications and meet or exceed Ding UV specifications. The TUV will participate in the construction of the owner's power station throughout the entire process, from the EPC side to apply, evaluate the project cost, evaluate the test plan, and provide full business intervention.
Xu Hailiang also stated that the certification cost of TUV is related to the project scale, and the perfect quality control is around -3 cents/W. At present, although the national standard has not yet issued the corresponding national standard, domestic CQC and CNCA etc. are already actively formulating relevant standards.
Xu Hailiang believes that the commercial market for distributed quality monitoring, testing, and acceptance has just started, but subsidies for electric power will surely make investors aware of the importance of quality, and third parties also expect to increase investment returns and reduce investment risks through technical services. The growth of third-party technology services in distribution should be explosive. The problem that the O&M market has been slowed down and the sunlight power supply can't be ignored is that this year Huawei began to enter the operation and maintenance market in large scale and faced the sunlight power supply. The industry is worried that the market share of Sun Power will be eroded by Huawei.
Zhang Xucheng introduced that Sungrow Power provided system owners with solutions for the power plants, including insurance for the owners, 3 years of free smart operation and maintenance, conservation of power generation, and application for carbon trading.
Zhang Xucheng further explained that China's carbon trading market has declined in the past few years, and since the trading volume began to recover last year, Sunshine Power is preparing to put the Yima fashion project on the Shenzhen Stock Exchange transaction, according to the current price of about 70 yuan per ton. The Yima fashion project can earn 70,000 yuan a year through carbon trading.
Zhang Xucheng also introduced three years of free operation and maintenance provided by Sunshine Power. If Wang Wang, in three years, he will help the industry king establish an operation and maintenance system, and cultivate the operation and maintenance talents. Solar Power can monitor the operation of each component of the power plant at any time through remote operation and maintenance and background monitoring.
For Huawei, a powerful opponent, Zhang Xucheng believes that Huawei's intervention is a good thing for the solar power supply, which promotes the progress of the solar power supply from the side. However, he did not think Huawei had any advantage in competing with Sun Power. First of all, Huawei's current strategy is to focus on string inverters, because its previous accumulation in the field of communications power, Huawei has advantages over low-power products. However, for China’s national conditions, the western large-scale power plants are mainly suitable for the use of large-scale inverters. In this area, China’s previous experience in communications power supplies is of no use. The future trend of inverters should be "larger, smaller, smaller." Huawei has only caught a small one. This is a strategic mistake.
Secondly, Zhang Xucheng believes that Huawei's data maintenance and operation domain is based on a relatively small data base. Whether it is grid data or optical resource data, Sunlight's data volume exceeds that of Huawei. At present, the total number of solar power stations participating in the global power system has exceeded, but Zhang Xucheng Frankly, Huawei's brand has a great influence, and its lucrative marketing model is worth learning, but for the current situation, Huawei has not eroded the original market of solar power.
The metal, typically a non-ferrous alloy such as aluminum, is melted in the furnace and then injected into the dies in the die casting machine. After the molten metal is injected into the dies, it rapidly cools and solidifies into the final part, called the casting.
The castings that are created in this process can vary greatly in size and weight, ranging from a couple ounces to 100 pounds. One common application of die cast parts are housings - thin-walled enclosures, often requiring many ribs and bosses on the interior.
Metal housings for a variety of appliances and equipment are often die cast.
Several automobile components are also manufactured using die casting, including pistons, cylinder heads, and engine blocks. Other common die cast parts include propellers, gears, bushings, pumps, and valves.
