Held on October 19 PV modules, inverters, battery three photovoltaic equipment tender scene, the re-emergence of the equipment manufacturers competing prices tendered popular phenomenon. According to Beijing to participate in bidding for a PV inverter business-related sources, inverters and battery equipment tender bid showing a clear phenomenon of lower prices, the lowest offer basically the same equipment than the international market price of low out more than half. In contrast, the PV modules offer more rational number.

It is understood that Beijing this PV off grid inverter factory quoted a bid price of 0.86 yuan / watt, compared with 0.69 yuan / watt minimum offer higher than 0.17 yuan / watt. The international market for PV inverters up to 1.5 yuan / watt or so.

The company official said that if successful, the company can be mass-produced in accordance with this price, it is expected to achieve profit not to lose money, prices are low, then the company is difficult to bear. However, the person thinks, as the company's comprehensive strength is good, to 0.86 yuan / watt bid price of the basic problem.

Experts said, inverters gridtiepowerinverteronline and batteries is mainly due to competitive bidding, has been the manufacturer of the two industries, mostly domestic, domestic market competition more fully, the number of manufacturers are also many within the industry, including domestic battery manufacturers, the more up to hundreds, so fierce bidding.

In contrast, most of the PV module market in foreign countries, China's PV module manufacturers in small quantities, the final product is mainly sold abroad, so in this round of bidding, although the overall PV modules offer is low but relatively rational , the gap with the international market price nor too large.

Among them, 10.5 yuan / watt price by domestic PV manufacturers Baoding Yingli quoted, according to experts predict winning is basically no doubt. In addition, the Shanghai Solar Energy Technology Co., Ltd. reported a 10.8 yuan / watt price, Shandong Connaught reported a 11.5 yuan / watt price.

The Suntech reported a 12.55 yuan / watt price is relatively higher, analysts predict that Suntech quoted price and the current international market price gap is not, the company reported this price may feel short-term product sales company has a direct relationship to worry about. It is understood that due to the recent international PV market hot, many domestic large-scale PV module supplier orders are received hands continued until late next year.

China Renewable Energy Society, Vice Chairman Xu Honghua, said the selection of "Golden Sun Project" qualified equipment suppliers on the one hand the main purpose is to reduce equipment costs through price bidding, and then expand the size of the market and began to cultivate the domestic PV market, and the other On the one hand is through the big industrial scale to indirectly promote the domestic photovoltaic equipment manufacturers bigger and stronger.

As a result, experts predict, it is possible to win this round of bidding equipment manufacturers should be strong comprehensive strength and scale of the enterprise, which to the greatest extent possible to ensure the future "Golden Sun Project" equipment quality and operational quality. Previously, the United States proposed to China New Energy 301 investigations, largely on the "market controlled by others," the photovoltaic industry is a big psychological impact. PV industry insiders said that if the real implementation of the new energy 301 survey, the domestic photovoltaic products exports will cause setbacks, so in order to reduce the risk of photovoltaic industry, and gradually start the domestic PV market is a matter of time.

SMA Solar Technology has delivered its independent grid connected inverter system, the supply of these systems are based on the German Technical Cooperation (GTZ) and the protocol.

GTZ project called Ethiopia access to modern energy services (Ames test - E), the project is aimed at improving the country's electricity supply. GTS international cooperation and sustainable development by the federal agency has.

SMA has been submitted last year in the first phase of the project 50 sets of dc ac converter, the remaining 50 sets of independent solar power AC-coupled inverters are installed in the remote rural areas of Ethiopia. Independent power plants can be output 1.5kWp, will be used to power microscopes, centrifuges, refrigerators, sterilizers and other key equipment.

SMA off-grid systems, vice president Feld that "With this scale projects, we can greatly assist in the mountains of Ethiopia in particular, better power supply is used to connect independent medical clinic, we believe that solar energy power will be able to ensure the health of power protection.

Micro-inverters and distributed maximum power point tracking (MPPT) solution as a PV dc ac converter market in the emerging field, is expected to grow significantly, from 2010 to 2015 the average annual compound growth rate of up to 77%.

     From the point of view of power systems, photovoltaic technology focuses on the following two aspects. First, from the perspective of photovoltaic systems, photovoltaic industry is one of the biggest challenges facing the shadow of the solar panel problems. Shadow changes, solar panels and panels of aging on the dirt, the voltage of the panels will be on impact, causing the output voltage in series with the panel changes.

Micro-inverter will be one alternative solution, it can achieve in the panel-level maximum power point tracking (MPPT), has the advantage beyond the central inverter. MPPT solar panels can be made ​​in each optimal power point, without the need for serial solar panels arranged in series, can minimize shadowing problems. The second is from the perspective of power devices, since the main PV system vendors have their own patent application PV inverter topology, semiconductor suppliers must develop specific products.

Therefore, these companies need to keep evolving solar inverter market emerging technology trends. For example, the need to increase the input voltage to achieve greater efficiency, it is necessary to use 650V or more MOSFET / IGBT. You might also want to use SiCSBD as a complete solution. In addition, to expand the market share of more than 10kW, you must use IGBT / SPM modules.

     For below 10kW grid-connected photovoltaic inverter solutions, Fairchild provides field stop (FS) IGBT and SupreMOSMOSFET devices have entered the market with the necessary high performance and high reliability low EOFF advantage. For micro-inverters, Fairchild has a medium-voltage MOSFET and SupreMOS technology to provide superior performance for such applications.

German housing market overheating, making the system integrator Phoenix Solar's business has been warmer. As of the end, Phoenix Solar's solar inverter and components may appear shortage.

     The company released third quarter earnings in 2009, when that component prices in Germany during the first half of this year continued to decline. While prices stabilized in the third quarter, Phoenix Solar's orders in large numbers.

With higher income and falling prices, the German market will continue to flourish. Phoenix Solar is a German company expects most dramatic year ever, although initially slow momentum of development, but this year will greatly exceed the amount of solar installations in 2008. The company expects the German new installed capacity will reach 2.5GW, compared with 2008 increased by 60%.

     Phoenix Solar  http://www.gridtiepowerinverteronline.com/  also said that November's installed capacity will be 400MW, while the historical highest installed capacity of 300MW. Utility solar projects under the German market was once so sluggish. Financial aid is not limited the development of the project. More importantly, the process to obtain funds in accordance with strict criteria, bank loans are no longer applicable, which led to delays in many projects. This situation also affected the Phoenix solar energy, there are many orders have been lagging behind.

     The company noted that the Spanish market has been funding problems in the region can only install 130MW.

     Spain, however, the market may be delayed projects has improved, which can alleviate the need built in 2010, needed items.

     Italian market in the first half module prices, along with installed capacity is reduced. Stable prices and supply increases, so demand has been warmer, installed capacity this year may reach 250MW. French market is gradually improving, but now faces the long-term needs the approval process, the amount of all hinder the installation. Even so, the French market is expected this year, up to 150 MW.
