Cow magnets are popular with dairy farmers and veterinarians to help prevent Hardware Disease in cattle. While grazing, cows eat everything from grass and dirt to nails, staples and bits of bailing wire (referred to as tramp iron). Tramp iron tends to lodge in the honeycombed walls of the reticulum, threatening the surrounding vital organs and causing irritation and inflammation, known as Hardware Disease.

In 2015, China's new photovoltaic power generation installed capacity of about 15GW (1GW = 1000MW, 1MW = 1000KW), an increase of more than 40%; the cumulative installed capacity of photovoltaic power generation in the country reached about 43GW, surpassing Germany to become the country with the largest installed capacity of photovoltaics in the world. The popularity and prosperity of the exhibition also largely reflected the growth of the Chinese PV industry.
One exhibitor expressed his feelings to the news that there were few SNEC exhibitors seven or eight years ago, and basically all of them were Chinese companies, and the customers were foreigners. In recent years, people have been more than a year, and the audience is also diverse, beyond the scope of the industry. At this year's show, Chinese companies are the absolute protagonists, and only a few foreign exhibitors are not big, which is also special compared with other energy exhibitions. Chinese PV companies have demonstrated the latest products throughout the entire industry chain, from high-efficiency components to photovoltaic finance to photovoltaic applications, smart management software, say thousands of thousands, are trying to resolve the industry's ills, reduce photovoltaic power generation Cost, and finally get rid of subsidies to achieve parity online.
Behind the blazing, some people have raised cold thinking. Although many manufacturers such as components, batteries and silicon wafers have announced capacity expansion plans, GCL-Poly CEO Zhu Zhanjun believes that the adjustment point of PV benchmark electricity prices is approaching on June 30, and the decline in subsidy standards has caused investors to force upstream companies to cut prices. Upstream PV manufacturing companies are facing tremendous pressure from both demand and selling prices. "The days when small and small purchases of silicon materials to make some silicon wafers are all gone," he said.
Efficient components, photovoltaic manufacturing
“The core problem that currently restricts the sustainable development of China's PV industry lies in the scarcity of high-efficiency component capacity, the severe decline in PV module components, the decline in investor income, the inability of the component to generate electricity due to environmental impact, and the frequent complaints about component quality. Sex factors have directly affected the investment income of power station projects." Yang Liyou, general manager of Jinneng Clean Energy Technology Co., Ltd. (hereinafter referred to as Jinneng Technology) told the news.
At the first Jinneng Technology Developer Forum, Jinneng Technology demonstrated three high-efficiency polycrystalline modules, high-efficiency back passivation monocrystalline modules and ultra-efficient heterojunction components. “The company currently produces 270W high-efficiency components. The ratio has exceeded 78.29% and is in the leading position in the industry. (The remaining first-line manufacturers account for 5%-10%)
Yang Liyou also stressed the importance of “photovoltaic wisdom†for quality control. Jinneng Technology adopts online monitoring equipment, data analysis center host, and automated production machine to intelligently monitor the processes of texturing, diffusion, etching, test sorting, etc., to achieve precise control of the production chain, and ultimately achieve production automation and intelligence. And traceability.
Yang Liyou believes that to reduce the cost of photovoltaic power, it is not enough to reduce the cost of component manufacturing and improve the efficiency of components. Jinneng Technology also plans to start from the tracking system, inverter system, intelligent control and financing costs to create Jinneng Photovoltaic. Ecosphere.
In addition, Jinko Energy announced during the exhibition that it has achieved more than 20% of high-efficiency polycrystalline battery mass production, and is expected to achieve more than 20.5% mass production efficiency during the year.
Photovoltaic smart cloud platform
At present, the construction of domestic PV power plants has entered a period of rapid development, and the problems of sustainable operation have become increasingly prominent. How to control the operation and maintenance, equipment failures and safety risks in the production and operation phase, how to improve the monitoring and management timeliness and monitoring data analysis ability? As a result, the photovoltaic big data management platform has become a battleground for the military. A similar software platform has been introduced, whether it is a manufacturing end, an operation and maintenance terminal or a third party. In addition to troubleshooting and early warning through big data, reducing operation and maintenance costs, and improving power generation efficiency, it can also provide endorsements for asset securitization of photovoltaic power plants.
During SNEC, Shanghai Aerospace Automobile Electromechanical Co., Ltd. (hereinafter referred to as Aerospace Electromechanical Co., Ltd.) launched a self-developed photovoltaic power station operation and maintenance management platform - eHorus Smart Cloud, from photovoltaic power station operation and maintenance, inspection and evaluation, monitoring and big data applications, intelligent management System development applications and other "one-stop" intelligent management overall solution.
“In 2014, we inspected the entire domestic PV operation and maintenance software and foreign operation and maintenance software. I found such a problem, like SAP software, is a crystallization of all humanity or advanced management experience in the world. SAP's functions, combined with its own management, will inevitably play its role. However, the operation and maintenance software is not like this. Photovoltaic power plants are emerging in recent years, there is no process of knowledge and data accumulation. So, software companies The developed software can't accumulate this knowledge, experience and data in the software, so we decided to develop the EHORUS intelligent platform independently.†Xu Jie, general manager of Shanghai Aerospace Automobile Electromechanical Co., Ltd. (hereinafter referred to as Aerospace Electromechanical Co., Ltd.) News (represents that the aerospace-class eHorus Smart Cloud software products will be introduced to the market in free form, but the business model behind it is diversified. For example, Aerospace Electromechanical can provide the owner with an annual medical report based on big data and provide data analysis. Services, etc., in the future, you can also use the data accumulated by the platform to make power generation And sale of electricity. "EHorus is our tool, the tool never expect a profit."
Yu Rongzu, chief engineer of Aerospace Electromechanical Co., Ltd., said that compared with the existing operation and maintenance software, the eHorus smart cloud has a competitive advantage in millisecond-level data storage and constant-time retrieval.
In addition, Jing Jing, vice president of Jinko Energy, told the news that although it is difficult to say that photovoltaic financing is difficult, the bank is also very wronged. Since the current return on investment is not bad, there is also a steady flow of cash, which is the preferred target of the bank. “Why is the bank holding a wait-and-see or very cautious? Because it is a stranger to him, it’s not like selling a bottle of water to immediately distinguish between good and bad. A power station or component, whether it’s financing a manufacturing company or financing a power station, The people lack a criterion for judging." Therefore, the emergence of intelligent platforms and the openness of power generation data for power stations can provide a basis for banks to understand revenue.
Also optimistic about the asset management with big data, Apollo Photovoltaic Cloud exhibited by Smart Energy Management's Vision Energy relies on the big data measurement model to help developers and investors realize the life cycle data management of power stations, including stable data collection and secure storage. Strict auditing, accurate analysis and in-depth excavation, using the big data to drive the fine management of photovoltaic power plant assets, so that the power station assets preserve and increase value.
Photovoltaic agriculture: photovoltaic and agriculture, which is preferred?
Photovoltaic agriculture has ushered in a wave of investment in recent years. Due to the commonality and complementarity of land use in photovoltaics and agriculture, coupled with policy support, the concept of photovoltaic agriculture is highly popular. However, some insiders said that many enterprises are playing the guise of photovoltaic agriculture, staking around the land, occupying land to build ground power stations, and planting things on the ground. The agricultural benefits are not cared for. In addition, some companies have carried out propaganda and speculation in the name of photovoltaic agriculture, but in fact they are pursuing tax incentives and financial subsidies.
Does PV agriculture give priority to the development of photovoltaics or agriculture? How is the balance between the two benefits?
“We have more than 30 types of sheds, which are set according to the characteristics of different crops. Some are completely free of light, such as edible fungi, the other is low-light, and glare, which needs to be in the shed. The design is on the mind, not at the expense of the quality and output of agriculture.†Li Jianzhi, chairman of Changsheng Solar Power Technology Co., Ltd. (hereinafter referred to as Changsheng Nidec), said frankly that photovoltaic agriculture is indeed mixed, many companies Because the project that I want to do can't land, I borrowed the name of photovoltaic agriculture, but the strict restrictions imposed by the competent authorities on the resale of roads and the growth of professional photovoltaic agricultural enterprises will push the aforementioned enterprises out of the market.
Li Jianzhi believes that many people look at agriculture and look at the small ones. When they say agriculture, they think of vegetables. When they think of the greenhouse, they think of anti-season dishes. In fact, the scope of photovoltaic agriculture is very large, aquaculture, forestry, seedlings are large agricultural areas, including photovoltaic sand control also has a lot of space.
During the exhibition, Changsheng NEC and Huawei signed a comprehensive cooperation agreement. According to Li Jianzhi, in addition to improving power generation efficiency, Huawei's string inverters can also be used as a transmission interface to collect various basic data related to agriculture, laying the foundation for the next step of organic agriculture and agricultural informationization.
