Following the success of CIMIC finalists "Golden Sun Demonstration Project" grid-connected photovoltaic inverter supplier, recently, Delta photovoltaic grid inverters successful bid Haining Leather City 3.6Mwp user side photovoltaic demonstration project, becoming the EPC contractors, construction on the roof of its power grid-connected photovoltaic power generation system, providing clean energy power leather city's users.

Haining Leather City is the country's largest leather market, but also large electricity Henin, the annual electricity consumption of up to 600 million degrees, because it is a commercial electricity, Leather City must pay high electricity bills every year. Energy conservation in response to the government's call, Haining Leather City in strict accordance with the "Golden Sun" project requirements, I hope through the construction of large-scale photovoltaic power generation systems on large tracts of idle roof, build a strong power system to reduce dependence on the grid, reduce Corporate operating costs, but also to provide clean energy for the electricity users.

After receipt of CIMIC projects, according to the distribution characteristics of the city by way of the leather construction of each piece design consisting of power generation units and construction. When classified according to the design Leather reasonable capacity and construction of each of several regional load size, then the inverter with appropriate capacity, consisting of several separate power generation unit, and multi-point network. In response to the demand for outdoor installation site, the project decided to adopt protection class IP65 Delta photovoltaic grid dc to ac power inverter for networking, the photovoltaic power generation systems and power inverters installed outdoors, and using multiple access way network, in order to ensure the PV generated electricity can be consumed nearest to achieve self-occupied, improve the utilization of photovoltaic power generation.

The entire project, CIMIC and using nearly 200 20kW power inverter with charger as the core network equipment, PV modules produce direct current is converted into alternating current and fed into the AC line for users. After completion of the project put into operation, is expected to generate around 3.5 million kwh per year, nearly half of the city of Haining Leather solve energy needs.

The project will end in close contact with the electricity generation side together, not only reduces the eastern region of scarce resources - dependent on the land, and the project is close to electricity demand side, directly reduce the loss of power delivery when; reduce the public grid electricity needs, and can effectively ease the power shortage in seasonal, local power supply is an effective supplement. Not only that, after completion of the project, but also save standard coal annually about 1,600 tons, 4,800 tons of carbon dioxide emissions, energy saving significant social benefits, has a good demonstration effect.

Frequent policy, 2013 is expected to become the demand of the outbreak: Recent photovoltaic industry policy frequent, reflecting the central government to support domestic demand started photovoltaic clear attitude. Determined according to a recent National Energy Economic Work Conference targets 2013 domestic demand will grow 2-2.5 times the 4-4.5GW in 2012, based on the scale to reach 10GW. The follow-distributed subsidies, renewable energy quota system, grid compulsory acquisition policies will gradually strengthen 10GW target to achieve this degree of expected;

The inverter link will directly benefit from the rapid growth of industry needs: a volume perspective, domestic demand rose the most direct and the biggest benefit should be part of the installation of photovoltaic inverters, mainly due to localized supply grid tie inverter its shipment growth will be substantially equal to the growth rate of domestic demand, it will be shipped in all aspects of the highest growth sectors;

Substantial growth in demand will reverse the price decline; we think prices will stabilize in the first half, the second half is expected to rise even: Before we caution the industry is due to increased competition in the industry from 2011 to 2012 resulted in a price crash, the formation of the gross margin squeeze. However, recent policy changes in the frequency of most businesses expected demand, prices have started to stabilize. If the second half of the shipments into the country's installed capacity peak phase in the case of tight capacity, prices are likely to rebound in;

Core inadequate supply of raw materials stage, will limit the effective capacity, while prices rose to become a catalyst: Another factor that may lead supply industry is not quick release and other core components such as IGBT supply. The same happened in the last round of the cycle (2009) when crossing. This will cause the dc ac inverter supply chain bottlenecks occur, thus further pushing up the price of the inverter.

Because the operation is very robust, the whereabouts of the social security fund has been closely watched, its operating strategy for ordinary investors with strong sexual references. As 2013 came to an end a quarterly listed companies, social security funds into the new year, the company also surfaced. Surprise is that most people, a quarter of the social security funds for favored companies turned out to be one of the GEM Listing PV companies - Sunshine Power (300274.SZ). Over the past year, and photovoltaic solar companies have experienced a share from Zhongxingpengyue to abandon if Bilv ups and downs, has still dip Xiongtu; behind NSSF now Adversity gallon, in turn reveal how mystery?

Unlike most domestic photovoltaic enterprises is different, the power of the sun is not the main business of traditional raw materials or battery components production, but the PV inverter R & D, production, and its market share of PV inverter stable domestic market for many years head chair. This year in April, the company developed for the North American market, a series of PV inverters have been applied to a number of rooftop PV systems in Ontario, Canada, more photovoltaic grid projects will be implemented in Canada. In addition to the PV inverter business, sun power is developing other new profit growth point, including storage inverters, electric vehicle motor controllers and other applications for new energy products, as well as photovoltaic power plant EPC projects, etc., and add Large open up to Asia, America and other overseas emerging photovoltaic markets.

Since late last year, in the face Europe "dual" sniper encouraged to expand the domestic market, domestic PV start stepping up and start to improve as a national strategy. It is "Spring Plumbing ducks", with the gradual open the domestic market, has been steadily rising installed capacity target for photovoltaic power generation system provides the core components of the inverter market demand lead to heat up, because each and grid-connected PV systems require an inverter converts the direct current into alternating current.

Especially in large-scale distributed PV to promote the building of domestic PV installed capacity is expected to usher in more growth exponentially. As an important part of the photovoltaic industry chain, the inverter charger industry undoubtedly will directly benefit from it.

Industry bodies IMS Research had expected, by 2016, global inverter shipments will reach 60GW, the market will reach $ 10 billion. With the rise of the shrinking of traditional and emerging solar photovoltaic market, the global inverter market structure will also face a huge adjustment.

Although 2012 still holds 54% of the European global shipments by 2014 this proportion will decline to 40%. From the quality point of view, China inverter inverter gap with international brands is gradually narrowing, more and more customers are beginning to accept Western China inverter http://www.sungoldpower.com. In particular, it should be noted that Europe's China "dual" always for polycrystalline cells and modules, but did not affect the inverter;

Therefore, including sunlight power, Guruiwate new energy inverter manufacturers, including its overseas market share did not decline, export demand is not affected. On the other hand, the domestic support policies affect the entire industry chain, the equivalent of the inverter and broaden the domestic market's door. Driven by the start of the domestic market to accelerate applications, compared with the component industry is still winter, photovoltaic inverter has presented the "Blue Ocean" situation, and has triggered competition for foreign manufacturers have a rare piece of cake.

Recently, the State Development and Reform Commission issued a 2013 strategic emerging industries (energy) of the first central budget investment plans (NDRC Investment [2013] No. 1029), DAY electrical megawatt photovoltaic inverter R & D platform project was included in the "national strategic emerging industries (energy) projects," and get special funds to support the central budget project.

Since last year , the EU launched against the export of dual PV modules since the survey , development of photovoltaic industry on the verge of collapse state, where photovoltaic manufacturing enterprises in ZhejiangProvince last year, about 80 percent of production. Although the state has promulgated a series of policies stimulating domestic demand of PV , but the overall development is not much improvement , joint development of the PV inverter industry Difficult .

PV inverter shipments fell slightly appeared in 2011 , but is expected to double by the year 2015 is expected to 52GW. According to market research company said this PV inverter shipments in the year 2011 from the previous year 23.6GW fell to 23.4GW. 2013 PV inverter sales will drop 20 percent to $ 20.5 billion , a decrease of $ 5 billion more than in 2012 . This is due to the global PV installed capacity and PV module average selling prices caused .

2012 global PV installed capacity reached 32GW, an increase of 14 %, an increase in market demand in Japan , the country started by distributed generation is expected in 2013 will be maintained at more than 10 % growth.

Meanwhile, in 2013 , the challenge inverter manufacturers will continue to face include certification standards , lower cost base and local manufacturing requirements and intense competition from local suppliers . 2013 could be another challenging year , global revenue growth was flat , the traditional market will gradually shift supplier base will be remodeling.

Since the inverter prices continue to decline, as well as Japan , China , India and other emerging markets is difficult to penetrate the United States may lead to growth in emerging markets could not compensate for the decline in core markets such as Germany and Italy , the world's ten largest PV inverter manufacturer will probably suffer affected. As the benchmark price is very low in some Asian countries , the biggest obstacle next year inverter manufacturers face is that they can not get to make Europe profitable business operations in Asia.

With 15% of the PV http://www.sungoldpower.com inverter revenues declined , reaching 4.4 billion euros ( $ 6.1 billion ) because the average selling price decreased by 14 %, which is higher than previously expected 10%. The market research company expects shipments of PV inverters will rise 5 percent in 2012 , reaching 24.5GW. This will be between 2013-2015 shipments expected to reach 52GW power structure .
