The face of rapid cell and module prices fell , leading to overcapacity , the photovoltaic industry has called for the need for up to one year of photovoltaic electricity costs per kWh (LCOE-levelisedcostofenergy) is reduced. Global Technical Director Mr. DuPont Photovoltaic Solutions Dr.HOMERANTONIADIS said , the application of advanced materials and technology is a key component to improve the quality while reducing costs.

In response to this strategy , DuPont has been ready for some time , to the gradual improvement of the technological revolution in the industry costs. DuPont ™ Solamet ® PV17x based technology platform , low surface concentration diffusion (LightlyDopedEmitter) has quickly been adopted for use in single-crystal and polycrystalline cell industry , can contribute to efficiency 0.15-0.5 % ; silicon ink (SiliconInk) in selective emitter platform (SelectiveEmitterPlatform), this process simply add a step , almost standardized battery manufacturing process ; backplane and uses DuPont ™ Tedlar ® film made ​​by performance verification prolonging the life of the component. Making photovoltaic energy in the traditional contest even more competitive.

General Manager Mr. Emerson Network Power Solar Power Solutions highlighted 10 factors affecting PV power plant generating capacity , energy efficiency principles of large-scale photovoltaic power plants generating logic operation, modular + intelligent sleep technology to improve efficiency, extend the time electricity technology, and modular + intelligent sleep technology to improve power quality practical applications. Emerson by providing customers with end-to- generation intelligent PV system solutions that enable photovoltaic power plant output can be an endless stream of more energy .

As mainstream silicon solar cell manufacturing technology , screen printing to improve cell efficiency to promote the declining cost of solar power has played a pivotal role. Zhu Bo Applied Materials China, Solar Products Marketing and Sales Director for the audience in detail the evolution of the secondary screen printing in printing technology , the development of selective emitter technology, and metal wear around technology (MWT) back- contact cells , etc. industrialization of the latest developments . Screen printing resolve the future path of development.

With the domestic market of large-scale photovoltaic applications started downstream photovoltaic industry has also ushered in a new round of landing tide , with photovoltaic inverters most rapid development . Since before the PV solar inverters core technology, as well as most of the market share of the five largest companies are international monopoly . But after the aid of the advantage of Chinese enterprises , standing on the shoulders of giants come from behind , and achieved remarkable results. Dr. Fu Cheng Jiangsu Baofeng New Energy Technology Co., Ltd Technical Director elaborated on the key PV inverter technology and solutions. Let us see, with the key technologies and speed the pace of domestic equipment , and promote further decline in the cost of photovoltaic power systems being struck in the face .

Of course , China must also exist some problems in the rapid development of photovoltaic inverters simultaneously , we need a rational treatment. Dr. Chen Xiaogao Energy Corporation Product Manager Samil show the audience the global PV inverter DC TO AC standards (European standards, North American standards , the Chinese standard ) , resolves the new standard for photovoltaic inverter design impact ( frequency characteristics , voltage characteristics , grid support , etc. ) , and proposes measures for specific problems and developing strategies to deal with ( the new standard for the challenges of the different proposed , given the appropriate response measures and strategies proposed inverter ) . Samil Power in the selection of key components are used internationally renowned , has a reliable guarantee of quality and performance components , in response to various challenges to gain market recognition of outstanding achievements and excellence .

Recently, Ying-Wei special New Energy Technology Co., Ltd. R & D Center gathers a group of senior engineers, after a long hard study, developed a stable, high-quality second-generation 12V600W off-grid inverters, has successfully completed the trial production has been put into mass production.

ESI-600VA series of off-grid wind grid tie inverter with digital intelligent control, all high-frequency conversion topology, stable performance, strong anti-interference ability. Rated input voltage is 12V/24V/36V/48V, the output voltage is 110V/60HZ, 220V/50HZ, rated power level 600VA. The products are widely used in communications, transportation, home, island, border, rural and pastoral areas, such as solar power systems.

It is reported that Yingwei special New Energy Technology Co., Ltd. was established in March 2011, is specialized in the development of new energy off grid inverter and controller product development, manufacturing and project solution design, systems engineering and integration service providers.

In fact , faced with the huge domestic PV market big cake , and government policy, " wind" , multinationals also withstand the temptation . Currently, the German solar leading enterprises "SMA Solar Technology Group " to  volt cable New Energy Co., Ltd. acquired love of 72.5% equity interest in the event , causing the PV solar inverters and the entire PV industry shake , voices of doubt heard this event .

"Now the photovoltaic industry turmoil , even SMA have been layoffs, reduce costs , and this is the main reason for Chinese companies they acquired . Merger brings reputation is bound to play a role in a number of major projects. Domestic counterparts in order to compete the project , may lead to more intense price war , but also should be noted, do not lose the product of domestic enterprises by foreign enterprises , and therefore , the acquisition further strengthened the determination of the Chinese brand-name companies do . " Feng Wei said .

Experts believe that the proper introduction of competition in favor of industrial development , but if a similar takeover further expansion could lead to outstanding foreign PV companies being acquired control of the domestic market . Business and government at the same time to solve problems , to guard against foreign giants of China PV industry chain, acquisitions and strategic layout.

With the growing competition in the industry of photovoltaic inverters , photovoltaic dc ac inverter large corporate merger integration and capital operation is becoming more frequent , more emphasis on outstanding domestic photovoltaic inverter manufacturer market research on the industry , especially for companies in-depth study of the development environment and customer demand trends change. The rapid rise of a large number of outstanding domestic photovoltaic inverter brand , becoming the PV inverter industry leaders .

Recently, Jiang special New Energy Technology Co., Ltd. R & D center set several senior engineers, after a long hard study, developed a stable, high-quality second-generation 12V600W off-grid inverters, has successfully completed the trial production , has been put into mass production.

Kyodo News, Japan's New Energy and Industrial Technology Development Organization (NEDO) 6 announced by industry, government, academia, the formation of joint technology research organization, "the next generation of power electronics research and development institutions," has successfully developed the world's smallest inverter. Compared with the general inverter, its size is only about twenty fifth, reduced to about 500 cubic centimeters. The outcome is expected to be applied to future electric cars and railways.

The inverter is a DC power into AC power apparatus, since the rotation of the motor efficiency can be improved, and thus commonly used in the field of home appliances, and the access procedure of the solar DC power generated in the AC power lines, or the inverter is also not missing devices.

The development of inverters silicon carbon compound material as a semiconductor element, instead of conventional silicon. Power conversion efficiency has been improved, in order to achieve miniaturization. Experiment, the inverter output power continuously driven the success of up to 15 kW motor, equivalent to more than 15 times the power of home air conditioning.
