Solar PV industry chain mainly consists of silicon purification, ingot / wafer manufacturing, production of photovoltaic cells, photovoltaic cell component production, application of five parts. In the industrial chain, from silicon to applications purification, getting lower and lower technical threshold. Accordingly, the number of firms are more and more, and the profits of the entire PV industry chain mainly concentrated in the upper reaches of the crystalline silicon production processes, the profitability of the upstream business was better than the downstream.
Past two years, private enterprises to enter the photovoltaic industry of Zhejiang, mainly in middle and lower reaches, including crystal pulling, slicing, slice battery, components, packaging and other fields, especially in component packaging Jishu threshold is relatively low, also the highest degree of corporate concentration Vostro A860n battery Winbook N4 battery .
Zhou Jianhong, general manager of Ningbo Solar Electric Power Co., told reporters that rising labor costs in the present circumstances, do not vitality of the component package. Particular, the recent price increases silicon without their own silicon solar cell plant or the component plant’s survival would be more difficult. According to reports, six or seven months of this year several of our province on the closure of the packaging plant.
To remind the industry of Zhejiang PV enterprises must focus on quality and features, must no longer follow the low-end copy of the old ways. Zhejiang Yuhui Yang Light Energy’s chairman Li Xianshou that the later will be required to use their brains at the equipment, accessories and other market segments make their own characteristics, this is the Zhejiang business advantage Vostro A840 battery Vostro A860 battery .
According to reporter investigate the province this year, in particular Jia, Shao-area there are dozens of businesses to invest in solar cell production. Many of them textile and other traditional business owners, to spend three million, built a two production lines. Zhou Jianhong reminded: “PV industry invested heavily, such as Yu-hui, Ningbo Solar such companies, a few years already invested billions of dollars. In the input, we must also consider the upgrading of product technology, as new industries technology, equipment updates fast. so many companies built production line, if you do not focus on technology research and development and reserves, the risk will be great. ”
Zhejiang PV many enterprises, but the “sub-mini”, objectively making at all levels of government support measures into a “diffusing” difficult to clearly focus on fostering business, photovoltaic enterprises generally face a lack of investment capital, technology platforms lack support and other problems. The industry believes that the province should be considered in this context, how to focus resources on core business, the relevant research institutions to focus on key technology research and development support. This is to avoid “low-end get together” key.
Looking forward,
“Hen” to lay eggs a lot of problems Vostro 1720 battery Vostro 2510 battery
If we compared the use of solar power to issue “eggs”, then the manufacture of solar power equipment is the “mother hen.”
Home and abroad generally cost photovoltaic industry is this: one made of crystalline silicon solar panels can be applied about 25 years, if installed in a solar power station, they are basically able to recover two or three years the manufacture and installation of all cost, the remaining 20 years can get all the rich benefits of solar power.
Obviously, “eggs” more money. Sales of solar light power generation equipment, mainly processing fees earned, is a little money and even hard cash. Want a higher return, it is necessary a lot of effort in the field of solar power.
According to the survey, Zhejiang PV companies are now focused on selling “hen” on, say, photovoltaic industry chain’s most profitable power generation has not yet set foot. This situation, in Jiangsu and other provinces in the photovoltaic industry in much the same Vostro 1710 battery .
Is the cost limit, or institutional constraints?
One reason: the high price of photovoltaic electricity.
According to estimates, the current cost of photovoltaic power generation at 1.3 yuan / degrees, can be expected within 2 years to 1 yuan / degrees. If the construction of PV power plant to reach 8% to 10% internal rate of return, discounted to PV electricity price concession projects, each degree of solar electricity at least to 1.4 yuan. The now traditional maximum power per unit of industrial electricity prices only 1 yuan.
Right now solar power and conventional electricity can not compete on price. Foreign large-scale application of solar power has been able, in addition to ecological concepts of first, the strong local government can not do without subsidies. In China, the government has not issued a strong and actionable subsidies Vostro 1520 battery Vostro 1700 battery .
Two reasons: the high input PV power station.
According to incomplete statistics, depending on geographic conditions and land costs, the photovoltaic power stations currently in the domestic investment cost per MW at between 20 million to 50 million yuan. Investment to build a solar power station, at every turn would billions of dollars, that private enterprises in Zhejiang Province, no doubt, a huge challenge.
Survey, many private enterprises of Zhejiang proposed capital into photovoltaic power generation, in addition to national policy support, the more necessary the introduction of financial innovations. PV power plant investment, can refer to the model building highways, to attract the trust and insurance institutions to enter, access to financial support to private enterprises. Like Yingli, Suntech, sunflower and other PV companies in trying to cooperate with foreign fund construction of photovoltaic power plants in foreign countries.
Three reasons: PV access to the Internet problem Vostro 1500 battery Vostro 1510 battery .
Many PV companies in the province’s manufacturing base to see factories and office buildings have been or are being installed on the roof solar power station, large 5 MW, there are small 2 to 3 mv. It is understood that these projects or demonstration projects for the national Golden Sun, or “solar roofs program” demonstration project. However, these self-issued solar power station, yet no one can be connected to the grid.
The reason given by either grid companies and network conditions are too harsh or is the power company that “technically possible” obstacles.
In addition, the state as early as last March 23 introduced a solar PV building applications financial assistance and temporary measure, the decision conditional on the part of the photovoltaic building for up to 20 dollars per watt subsidy. But now, the province most of these solar companies have not yet enjoy the preferential policies.
The intention to have a share in power generation in the field of private enterprise, the deeper the shadow of positive pressure to. August 10, China’s second batch of PV will be officially opening the tender, the tender amount will reach 280 MW, is by far the largest photovoltaic power generation projects. However, the current bid are mostly enrolled five major power giants such as central enterprises, private enterprises are very few. Some analysts pointed out, the face of the “lowest bidder” rules of the game and had to withdraw from public funding in addition there was no alternative. Of course, was that the cost advantage of private enterprises owned equipment and advanced technology, as a “supporting role” for the central enterprises to provide equipment and technical management. Prior to bidding on many occasions in the domestic state-owned enterprises and private enterprises have no lack of examples of cooperation Vostro 1310 battery Vostro 1320 battery
