After 10 years of development and application of solar water heater has spent the market introduction phase, began to enter a period of rapid growth. Cultivation base of consumers already laid, and a rapid growth period of opportunity is coming. The current energy crisis, the implementation of the national advocacy to create energy-saving social situation, and the National Renewable Energy Law ", will make some high energy-consuming power consumption is restricted, which in turn is the rapid development of solar energy products a rare opportunity, solarsoon will usher in a major product innovation and development opportunities. 

   Authoritative data show that in 2004 the national Photovoltaic Panels water heaters sold more than 12 million square meters, the entire solar industry output value of over 13 billion yuan. China National Hardware Association, according to statistics, China's urban households, 57.4% have a gas water heater, 31.3% have electric water heaters, solar water heaters only 7.6%, the proportion of the three, but in a survey of urban households purchase is expected to evolve into 35.8%, 30.2%, 23.2%, will significantly increase the proportion of solar water heater, gas, electric products started to become important competitors. 

The solar water heater is greater in the rural market space. According to official estimates, by 2015, the National Family Residential solar water heater penetration will reach 20% -30%, the market has a volume of about 232 million square meters. According to the relevant departments of the state survey shows, solar water heaters accounted for 11.2% of the entire water heater market, 30.6% of consumers will buy the water heater is solar energy. However, with the emergence of power shortage and solar water heater and the popularization of the case, the first choice of consumers to buy solar hot water system rate soared to 90.5%. 

According to the experts say, as early as the 1998 World Solar water heater to maintain the total of about 54 million m2, Cyprus and Israel's per capita use of solar water heater area ranks first in the world, respectively 1m2 / Japan and Israel, mppt solar charge controller water heaters, the proportion of households with the other points as20% and 80%, respectively. 21st century water heater will remain one of the most important market for solar thermal utilization, although many countries have been more widely used, but the world of solar water heaters average percentage of users is still very low, about 1% to 2%, and Japan 20 % and 80% in Israel, are very far; 

In addition, services, tourism, public welfare and other low-temperature hot water application market is also very large. 1997 World Solar water heater market of about 700 million U.S. dollars, about 70 million of the world's population in 2015, if the water heater users of 20 per cent (today's level), socio-economic and environmental benefits will be very significant. This shows that the energy-efficient products are becoming one of the highlights of the recent market, companies are making determined efforts to compete for energy-saving market opportunities.

In recent years, with global energy shortage and environmental pollution problems have become increasingly prominent, solar photovoltaic industry as the most promising clean energy industry is one of the countries in the world attach great importance to and rapid development. China's photovoltaic industry from the capital, talent, technology, and market high degree of integration with the international trend of industrial development, and full use of their advantages of rapid development, has become the industry one of the few able to synchronize to participate in international competition and has achieved a certain international competitive advantage. 

The past two years, solar panels for sale photovoltaic itself to a variety of structural contradictions, coupled with a deteriorating external environment, industrial development in trouble. 2012, downstream PV market weakness in the polysilicon industry at home and abroad continued to run low, the annual output of 64,000 tons, down 23.8% from 8.4 million tons in 2011. Competitiveness of domestic enterprises capacity is obviously insufficient, the 2012 domestic polysilicon total market demand of about 14.5 million tons, essentially flat with 2011; 

The polysilicon 2012 total imports of 8.28 million tons, an increase of 28% from 6.46 million tons in 2011, the polysilicon market more than half of the ravages of foreign enterprises, domestic enterprises market share fell to the lowest in nearly four years. A large area of ​​the domestic enterprises to stop production, widespread losses of enterprises, the average capacity utilization rate of less than 40%. Enterprise development situation, China has a the three polysilicon flexible solar panels production capacity of more than 10,000 t. Among them, Jiangsu Nengchan able to 6.5 million tons, production of 3.7 million tons, accounting for 61% of the total domestic production, far ahead of other domestic enterprises; Luoyang Sino-silicon, a large new energy, Asia Silicon production at 4,000 tons. 

4 polysilicon production capacity accounted for nearly 60% of total capacity, production accounted for about 82% of the country's total output. Judging from the competitiveness of enterprises, China's polysilicon production costs vary greatly, the industry has shown a structural surplus. China's polysilicon business skill levels, production costs less than 120 yuan / kg twelve production capacity accounted for 40% of the total production capacity of 8 to 12; costs 120 yuan to 180 yuan / kg, total capacity accounting for about 30%; 

Polysilicon enterprises the remaining volume accounted for 70%, the production cost of more than 180 yuan / kg, part of the production costs are still 200 to 300 yuan / kg. From production to distribution statistics show that PV companies in China production capacity of 3000 tons / year including the number of enterprises accounted for about 60% less than the 3,000 tons of annual production capacity, accounting for 18%; accounted for about 20% of the number of enterprises with more than 5,000 tons / year, production capacity accounted for 70%. The number of China's polysilicon enterprises still mainly small businesses. 

2012 PV industry-wide winter impact "disaster area" upstream polysilicon prices all the way down to the end of 2012 fell to 125,000 yuan / ton polysilicon offer.Polysilicon enterprises have ceased production of the majority of the country.Since 2013, the price of polysilicon emergent rising trend. As of the end of February, the domestic polysilicon prices rose to 138,000 yuan / ton, the continuation of moderate growth in March, the end of March prices exceeded 14 yuan / ton, up to 142,800 yuan / ton. The first three months of this year rose nearly 15% compared with the end of last year. But prices did not activate the boom of the industry as a whole. It is understood that in the second half of last year, domestic maintain the operation of the polysilicon business about 8, has been reduced to four, and are first-tier manufacturers.

Chinese Commercial News reporters learned dialogue scene at the Global PV leaders yesterday, supported by the Energy Foundation, the China Association of Resources Comprehensive Utilization Renewable Energy Industries Association (CREIA) will today officially presided over the "Chinese PV classification grid tariff policy research report release. In March this year, the National Development and Reform Commission issued "on improving the photovoltaic power price policy notice (consultation draft)", the benchmark price of the previous $ 1 per kilowatt-hour, according to the resource is divided into four regions were down 0.75 yuan, 0.85 yuan, 0.95 and $ 1.00.

Distributed generation subsidies only self-occupied part, the amount of $ 0.35 per kilowatt-hour, part of the grid by grid enterprises in accordance with local coal-fired power benchmark feed-in tariff for the acquisition. At that time, experts pointed out that the current policy has not subsequent messages specific price subsidies, subsidies lives and settlement, are not sure. Electricity price subsidy policy uncertainty, investors will not dare to invest. "

Now, however, the report in terms of resource criteria for the classification of photovoltaic benchmark feed-in tariff standards, the distributed electricity standard compared to the previous release of the draft are fine-tuning. First, the report depending on the total amount of radiation of the the photovoltaic inverter horizontal plane of Regional to China (excluding Hong Kong, Macao and Taiwan regions) resource area divided into four categories, based on the cost of investment and payback period, set to a different area of ​​photovoltaic benchmark electricity price .

Report settings, the annual equivalent utilization hours were a resource area greater than 1600 years, second-class resource area in between 1400-1600 hours, 1200-1400 hours between the three types of resources area, the fourth class of resources district convention equivalent utilization hours less than 1200 hours. Resources and power generation costs, according to estimates out applies to all regions of photovoltaic benchmark price for a class of resource area of ​​0.8 yuan / kWh, the two types of resource area of ​​0.9 yuan / kWh, the three types of resources area of ​​1.0 yuan / kWh, four types of resources District 1.1 yuan / kWh.

Large ground grid-connected photovoltaic power plants as well as focus on the development into the public distribution network project in accordance with where the regional implementation of the benchmark feed-in tariff. Grid by local desulfurized coal benchmark price of acquisition of the wind turbine inverter power generation projects the amount of the difference with by the National Renewable Energy Fund to make payments. Secondly, for distributed development, the spontaneous personal use power more than the Internet photovoltaic power generation system, due to its convenient local consumption, can reduce the damage caused by long-distance transport; same time, because of its user-based electricity tariff to provide subsidies, the state can reduce subsidies expenditure should therefore develop more economically attractive tariff subsidies to guide its development.

In view of the efficiency of the distributed development than large power plants has decreased, both encourage the development of fair income on the basis of the report of distributed photovoltaic self-electricity partition the feed-in tariffs in accordance with the the partition grid tariff increase of 25% calculated to determine the distributed generation internal control partition tariff, that is a kind of resource area of ​​1.0 yuan / kWh, the two types of resource area of ​​1.15 yuan / kWh, three types of resources 1.25 yuan / kWh, four types of resources 1.35 yuan / kWh.

The amount of subsidies given to the distributed generation internal control partition tariff subsidies for their own use photovoltaic power, which means high electricity prices to end-users in the same area, the amount of subsidy, low electricity prices to end-users, the amount of subsidy depends on user tariff floating Once the user tariff of distribution partition level of tariff subsidies stop automatically. Distributed photovoltaic power more than the Internet part, it is recommended that local desulfurized coal benchmark electricity price plus moderate subsidies, such as 0.2 yuan / kWh to be acquired.

According to Voice of the economy "CNR Financial Review reported, the EU solar panels" double reverse "the case preliminary results approaching, time is running out to start the domestic PV market. EU PV products will impose high punitive tariffs rumors with the EU is close to the preliminary results of the "double reverse" case of the solar panels in China, has long been rampant. Whether this news is true, according to the procedure, this proposal is a formal consultation process has been launched, once released on June 5 official announcement of the preliminary anti-dumping decision, the tax rate will be 47% tax will be up to five years.

In November last year, the EU began on Chinese solar panel production suppliers anti-dumping initiate an investigation, and ordered the EU customs registration of all imported from China solar battery board since March 5, the Chinese polycrystalline solar panels companies product exports to the EU into an unprecedented difficult period. If 47% of the heavy taxes levied photovoltaic industry in China, will enable the precarious worse. In this case, the development of the domestic PV market is to pick up the pace, the relevant departments issued a series of policies to support distributed generation, especially by many in the industry believe that is a good medicine to save the photovoltaic industry.

However, in some PV companies, the current policy is too macro, lack of rules, have no basis in the local executive, unprecedented reference, so that the policy is difficult to implement. In addition, with respect to the rapid development of commercial areas, our personal distributed generation project is still almost blank. The lack of a viable business model, the developer is difficult to intervene. In other words, the photovoltaic solar charge controller industry itself also has industrial innovation, the demand for upgrading. In the United States and Europe have put pressure on the situation, it is necessary to accelerate the launch of the domestic PV market.

The reason why the Chinese PV products popular in the European market, in large part by the high cost of labor costs, economies of scale and local leading triple advantage superimposed. Local PV companies in the European Union may be able to in the performance of certain advantages, but the price can not compete with their Chinese counterparts on the local market, it is difficult to produce a significant attraction for price-sensitive users. Chinese PV companies which is often the main reason to launch an attack.

For everyone concerned about the rate of up to 47%, the possibility of a tax? The final will be performed in accordance with such a high tax rate? Commentator Voice of the economy, China University of Petroleum Energy Institute for Strategic Studies, executive vice president Wang Zhen this comment. Wang Zhen: the matter does impact on the PV industry in China is very large. From the current situation, such a high punitive tariffs beyond everyone's expectations.

The average 47% to 67%, individual enterprises, 68% of such a high level, there is room for discussion, especially by government. Market interdependence, the EU and China solar photovoltaic industry in China is very large export amount, in this case, from the national level in terms of speed up and the EU communication and consultation, or to the entire PV industry That could be very deadly.

In fact, such a high tariff not necessarily all of the EU is a good thing, solar levy such a high impact for users is very large. In addition, the EU also needs China to cooperate with the EU out of the crisis, so my own views on the possibility of the imposition of this tariff great, is not imposed such a high tariff or worthy of discussion. Wang Zhen, levied in accordance with the 47% of this ratio is very high indeed, and for photovoltaic enterprises of China's exports to the EU, could be a fatal blow.
