Although after the "630", the price of photovoltaic Internet access will be lowered, PV companies will turn their attention to more distributed, but it is undeniable that so far, how do you start to distribute this "cake"? A proven method. It is foreseeable that the 2017 front runner indicator, the general ground indicator, the poverty alleviation indicator and the possible "super runner" may still be the main battlefield for everyone to "kill".
In 2016, the National Energy Administration issued a document encouraging the provinces to allocate photovoltaic power plants by establishing bidding, optimization and other competitive methods. Most provinces have adopted competitive evaluation methods to allocate indicators, while the key scores for evaluation are the price cuts of on-grid tariffs. It aims to push the technology upgrade through market competition. According to industry sources, the cost of photovoltaic power plant systems has dropped to around 5 yuan / W, and the cost of electricity has been reduced to 0.5 yuan / kwh. On the road to cheaper access to photovoltaic power, what is the current situation of inverters with a “heart†function in the entire system?
Is an illusion still a conspiracy? The competition of inverters has unconsciously jumped out of the price war game.
At the peak of 2012, there were about 300 inverter companies nationwide, and now there are about 100 inverter companies. In the next few years, there may be less than 30 inverter companies that can survive the market.
In terms of the price of the inverter market, the lowest price of centralized inverters fell to 0.1 yuan/W in 2015; on March 7, 2017, Guodian Investment announced the price of the tenth batch of inverters for 2017, the price is roughly The price is between 0.23 and 0.3 yuan/W, while the price of mainstream inverter companies is between 0.23 and 0.25 yuan/W. Obviously, the price of inverters bottoming out is no longer a decisive factor in the competition of inverter companies. In this regard, Mr. Li Yan, Marketing Director of Beijing Nenggao Automation Technology Co., Ltd. (hereinafter referred to as “Beijing Nenggaoâ€) believes: “Inverter market from the beginning of 'warlord melee' to the current 'warlord’s separatist’, In this view, the dominant factor in price occupies has become less and less. In the face of the upcoming 'oligarch era', technology, manufacturing and after-sales are the core competitiveness of an excellent inverter company."
The homogenization competition in the inverter industry has become increasingly fierce. Regardless of technological advancement or conversion efficiency, the product efficiency of domestic mainstream inverter companies has basically reached 98.5%. The price is no longer the decisive factor for the competition of inverter enterprises. The choice of inverter products is more rational, and the input-output ratio becomes the decisive factor for everyone to choose products. After all, 25 years of power generation is the enterprise income. The root of it.
"Only by seeing the reality of the market and the potential appeal of customers, technology leadership, refined manufacturing, and after-sales service system are undoubtedly the core 'three axes' of Beijing's ability to compete in the market." Li Yan said.
Technology leadership is one of the core competencies of all manufacturing companies. The leading edge of technology is the foundation of a company's survival. If it can be step by step, it can accumulate steps and even thousands of miles; whether it is from the perspective of enterprise competition or industry development, focusing on market situation and technological innovation determines the future development of the company. The important pattern. Beijing Nenggao is one of the initiators of the “Golden Sun†demonstration project and one of the drafting units of the inverter industry standard. The leading edge of its technology research and development is unquestionable. Whether it is centralized or string, large capacity or small capacity, 1000V or 1500V has its mature technical route and advanced.
During the SNEC period, Beijing Nenggao introduced the 1MW energy storage system inverter. Its innovations are: photovoltaic module and battery decoupling control technology, which can overcome the instability characteristics of photovoltaic modules and provide stable harmonic content for the grid. The pure current improves the quality of the power grid, can effectively solve the instability problem of the photovoltaic power generation system, realize the rapid control of the power grid, and improve the static and dynamic characteristics of the power grid.
"Manufacturing" and "transmutation" do not go through a lot of tests without crossing the thorns. Only by luck, they will only be surrendered by competitors. This is the market.
Manufacturing is the core of product stability. As an electrical appliance composed of many precision components, the stability of the system plays a vital role in the protection of power generation. Li Yan introduced to the author: "Beijing Nenggao guarantees product reliability and system stability, in addition to optimizing high quality components in overall quality, adopting advanced MPPT control strategy, advanced grid harmonics and three-phase unbalance In addition to the technology, the function of protecting the inverter itself from damage, we also pay great attention to the processing of the product detail technology. In terms of the heat dissipation problem of the inverter, the method of isolating the high temperature zone from the low temperature zone is adopted. Differentiate the components with different heat to maximize the service life, thus increasing the stability of the system. At the same time, we have adopted a targeted cooling method. For some highland areas, high salt fog areas, windy sand areas, air cooling Heat dissipation can cause blockage and corrosion of the air duct. By adopting a closed liquid cooling circulation system, the safety and stability of the system can be effectively increased, thereby effectively ensuring and improving the power generation of the power station. Beijing Nenggao is in this way of excellence. The recognition of new and old customers has made their annual shipments never lower than 500MW."
Market transactions seem to be cold, but service word of mouth is the "trump card" for long-term cooperation!
The after-sales perfection and service attitude determine how far this enterprise can go. A good after-sales service system is the key factor for PV power plant investors to choose products. Photovoltaic power plants are different from other power plants. Their high initial investment and long payback period make the 25-year power generation revenue especially dependent on the follow-up of after-sales service. Li Yan gave a simple sharing of the experience of Beijing Nenggao's after-sales service: “In terms of breadth, Beijing Nenggao will provide free technical training to the operation and maintenance personnel in the early stage of pre-sales, so that it can solve small problems quickly. Quick response on the after-sales network, even on the same day as the day of the report, to maximize the protection of the owner's power generation. In terms of depth, Beijing can be not only the inverter, but the entire The system carries out fault diagnosis and danger hidden danger mining for the purpose of achieving the effect of “treating the symptoms and curing the root causeâ€, thus effectively ensuring the power generation of the whole system and the safe operation of the equipment.â€
Looking at the distance of the development of science and technology, the road ahead, which one is the right way? How will the inverter go?
In the power industry, the speed of PV technology changes far exceeds other industries. The rapid development of the industry and the expansion of application scenarios will make the design of photovoltaic power plants in the future more refined; the system integration will be further improved, and the integrated inverter and medium voltage transformer will be integrated. The solution simplifies the system to the extreme while reducing costs, ease of use, and efficiency and reliability.
As the core equipment of photovoltaic power plants, inverters have a tendency to develop "intelligent" and "lightweight" in technology. Li Yan said frankly that in the near future, the inverter will not only play the role of 'heart', but it will also play the role of 'brain'. In addition to its proper function, the intelligent inverter will also Taking on more additional attributes. Beijing Nenggao, as an old-fashioned inverter company, has a deeper understanding of the intelligence of inverters. From two aspects: “One is the prediction of load, through the previous generation data. The collection, information processing, in order to carry out power generation scheduling, reduce the load on the grid in the case of ensuring the amount of power generation; the other is the real-time monitoring of the operating state of the array of components connected to it, through normal operation The recorded data is compared, an early warning signal is issued, and the fault is detected by itself, and the problem is found in real time. The lightweight of manufactured products is an inevitable trend. The lightweighting of products can not only achieve effective use of resources but also reduce environmental pollution during production. The weight reduction of inverter products, the improvement of inverter efficiency, and the application of new devices and new topologies should be based on the continuous reduction of weight to meet the difficulties of installation and maintenance and complex application environments to ensure the harsh environment. High reliability. â€
The competition in the inverter industry is as quiet as a master. The number of martial arts roads that the various factions are good at is not the same. When you come to me for a competition, you have lost the qualification to win Huashan, and see the factions. The number of master martial arts roads, who can be better.
