New energy semiannual analysis: PV start benefiting domestic distributed, lithium still do thematic investment opportunities

Low base and product prices recover, photovoltaic sector recovery in profitability . Since 12 years of industry as a whole in a difficult period, the profitability of the industry is low-lying period , many enterprises in the loss of the edge or even single year substantial loss . 13 beginning of the year , subject to the domestic Japanese market than expected and distributed generation policy support positive factors , cell and module prices have rebounded , midstream and downstream businesses started to recover , results are very flexible , most businesses profitable , substantial growth year on year .

In the EU's " double reverse " soft landing , silicon unconstrained case, we recommend attention to the most likely to restore profitability Takamoto shares . In addition , the domestic distributed power station is expected to be quick start , will drive investment opportunities in power plants and related companies stand out , the proposed focus fought in power plant construction in Central shares and sun powerinverter faucet .

Wind power, nuclear power to be good policy or event catalysis. In the first half , the whole price of wind power has moved from the lowest 3600 yuan / kw rose to 4000 yuan / kw nearby , gross margin rebounded. In addition, from 12 in the second quarter, the wind farm related significantly improve the company's profits , the equipment supplier's receivables owed ​​phenomenon began to decrease , wind power equipment company 's operating cash flow has greatly improved , we can see the entire wind power industry chain into a virtuous cycle , perhaps lying wind power sector performance period has passed , but still waiting for policy support to start or event of a catalyst. Although the performance of nuclear power is relatively stable , but we believe that its imaginary space is limited, temporarily held sidelines. Lithium plate subject of concern investments.

In the first half , on the one hand by the Tesla effect of lithium plate driven by sharply higher , the market for new energy vehicles are expected to start early ; the other hand, intelligent digital products for soft package lithium demand enables companies to rapid growth performance . We believe that the future investment opportunities in lithium plate will remain by the consumer electronics and new energy vehicles to drive .


Investment strategy advice: focus on three aspects of the investment clue: ( 1 ) distributed PV power plants driven by investment opportunities , mainly power plants and photovoltaic wind grid tie inverter integrators such companies ; ( 2 ) consumer electronics, smart , driven by demand for digital products soft bag lithium batteries and related raw materials manufacturers .

Sunshine Power: EPC as scheduled, in line with expectations, rather than-expected

Company Announcement : According to October 8, 2012 between the Company and Sanyang Jiuquan Jiuquan sunrise and signed 100MW of 900 million yuan ( tax included ) power plant EPC contract provides for a capital increase agreement , Jiuquan Jiuquan Sanyang sunrise and May 3, 2013 days to complete business registration change registration , no longer is the company's wholly owned subsidiary. The two companies each hold a 10% stake.

The contract for the EPC contract, the actual results contribute not only to a more limited ( expected net profit contribution of 50 million ) , and is expected within : Although the contract does not include taxes of approximately 800 million yuan , accounting for the company by the year 2012 audit 74% of revenue , but the implementation of the performance level, we estimate the contribution of net profit for 2013 of about 50 million or so. This contract is the completion of the equity transfer of the capital increase is in line with the terms of EPC project is expected to exceed expectations rather than within .

Profitability in the inverter 's judgment , we insist that the prices will not rebound but will decline, but prices fell gradually synchronous speed at lower costs , gross margin stabilized : the PV inverter price competition need to have full understanding of property as anasset-light inverter assembly manufacturing is difficult to form a similarasset-heavy upstream polysilicon price elasticity .

We have the cash and cost advantages that companies will not easily relax and let the market share price in the short term is difficult to see the inverter gridtiepowerinverteronline price trend rally. But the rapid decline in profitability period has expired , the future rate of decline in prices will gradually return to synchronous speed at lower costs . We expect the gross margin decline this year compared to last year narrowed substantially .

After last year's R & D and sales expansion , and complete the equity incentive this year, the expense ratio is expected to shrink a certain extent : Last year, the company increased sales and R & D , sales and administrative expense ratio increased by 2 percentage points each . From this point of view , we believe that the absolute value of sales and administrative expenses will remain stable, thus the management expense ratio and sales rate will decline.


The future of PV inverter assembly

PV inverter market recently surging, April 22 , ABB came news of the acquisition of Power One vibration industry . People have speculated that the electrical equipment giant and the world's second largest manufacturer of photovoltaic inverters marriage of what changes will bring the photovoltaic industry . With the major components of the market giants leave the flesh is different inverter market is indeed acquisitions frequently .

In early April, the Photon magazine was a very eye-catching German inverter manufacturer REFUsol acquisition by the U.S. company Advanced Energy late last year, the acquisition of the domestic industry a brother SMA cable manufacturers MeV love . The major manufacturers in the direction toward the bigger and more powerful strides , coupled with China's western photovoltaic " leap forward " , some domestic manufacturers that " one hundred kilowatts below the small loom we simply do not do it ."

Compared with the component , the inverter technology innovation more slowly . Especially large inverter with charger (utility-scale inverter) each topology (topology), control methods , switching devices are similar, but the stability of the product and the actual efficiency is need long-term experience in engineering design . On the other hand , large-scale projects also need to do this kind of technical support for localization , marketing, government relations, financial support, the future winner in doubt , but the multinational giants have been ahead of others in several ways .


But it is an entirely different story in academia , laboratories inverter is getting smaller and smaller . Engage in research of PV inverters should have read Frede Blaabjerg , Denmark Aalborg University professor and his students to write about the PV inverter (PV inverter) review articles . The article mentioned the inverter a trend , a large central inverters (centralized inverter) is already very mature past tense , then ( 2005 ) is more popular string type (string inverter) and communication components (AC module) / micro-inverters (micro-inverter), the future trend will be even AC battery AC component

How to choose inverter thin-film modules

New Energy Co., Ltd., Guangdong Bao Wei not only provide customers with professional stent design for the total package provides turnkey photovoltaic power plant construction services, with professional knowledge and rich experience, Paul Wei inverter for supporting the selection of components and also can give constructive comments.

Since crystalline silicon cell module fill factor is high, the peak point of the inverter is easy to find, but amorphous silicon thin film battery pack is relatively low fill factor, IV curve is gentle, the grid connected inverter need to set the step voltage tracking MPPT to find the peak point.

Meanwhile amorphous silicon thin film batteries need negative ground, in order to discharge static electricity and prevent common mode voltage to ground exceeds the system voltage and the inhibition photovoltaic array panels on the distributed capacitance of the inverter control circuit common mode interference. So you must use an internal or external transformer isolation (including step-up transformer) for grid inverters, grounding lines need to add DC leakage protection device to protect the personal safety.

Combining the above reasons, on negative ground can use the following improvements: negative ground is not grounding lightning protection components, but mainly to prevent static electricity, so you can use indirect grounding method, using a large value resistors indirectly grounded to avoid causing direct ground with no transformer-isolated modified sine wave inverter incompatibility problems.


Since the grounding resistor through the actual current is very small, will not cause the inverter without transformer-isolated DC leakage alarm, while the DC grounding line leakage protection settings can play a small role in protecting the safety of personnel. The only downside is indirectly grounded in the inhibition of cell panel distributed capacitance of the inverter reduces common mode interference aspect, and this problem can be reduced distributed capacitance (eg with no border component) and the inverter internal circuitry to improve noise immunity resolved, and now most of the inverter can be fit.

China PV inverter market is expected to turn for the better now

American and European solar PV market is almost Trina Solar, Suntech and Yingli Green Energy solar panels and the like Chinese manufacturers dominated. Leaving aside the trade war between countries aside, Chinese PV companies with its low-cost, high-quality crystalline silicon solar panels to win the battlefield. According to GTM Research Report, 2011, almost 50% of Chinese exports to the United States PV modules.

However, Research Solar Analyst MJ Shiao said on another important hardware photovoltaic system inverter, the Chinese companies in the U.S. market share of almost zero (this analysis excluded Satcon and Advanced Energy inverters manufactured in China ). At present, the inverter market is Germany and other European companies SMA American companies (eg Fronius,, Advanced Energy, Kaco and Satcon) dominated.

Each grid-connected PV systems require an inverter to direct current into alternating current. Chinese enterprises in the inverter market share in the U.S. and Europe is not following reasons: 1) the cost of PV inverter PV systems accounted for only 7% of the total cost, so a cheaper photovoltaic inverter does not System prices have much impact. Therefore, customers do not tend to choose cheaper Chinese production of inverters.

2) As many installers because of the quality, bankability and reliability issues do not choose China-made components, installers also less willing to choose China manufactured solar power inverter  This MJ Shiao, commented: "the entire PV inverter is usually the largest cause of system failure, so third-party developers and engineers tend to higher quality inverters."

3) MJ Shiao said, because the UL 1741 certification (some vendors take two years to obtain UL certification) is difficult to obtain, European manufacturers entering the U.S. market Pofeizhouzhe. Many manufacturers have made some progress, but want to get UL certification, or to spend energy. micro grid tie inverter enterprise Chint committed to becoming the first company to overcome these barriers Chinese enterprises.

Secret plug-in grid-connected photovoltaic inverters

Plug- grid PV inverter has emerged in Australia - what they are, how they work, you should also use one ? PV inverter is an electronic box will be solar panel array generates DC power (DC) into alternating current (AC), applicable to home appliances, and transported to the main grid .

Traditional solar inverters , solar modules can handle multiple output , usually installed in the meter box nearby. Micro-inverter , is a recently developed a new type of inverter, has a smaller size, can work with a single solar panel and installation of solar panels on the back on the characteristics , creating a commonly referred to as the AC solar panels.

In the family system, install the most common photovoltaic inverter requires a qualified electrician to operate, because they are qualified to the wire connected to the meter . The new " plug and play" inverters are very different - it is a portable device that can be solar panels or small wind turbines connected to the inverter, then directly into the family standard power inverter socket ; electricity for home appliances . Although less than a standard residential solar inverter capacity size, but can be used multiple units.

It sounds like a great idea , but consumers considering the purchase of plug and play grid inverter may need to be careful . In a forum on energy issues discussed at the problem, which is one point to mention , although Clean Energy Commission (CEC) will plug the inverter marketed renewable energy certificates and obtain approval (RECs), but in a important safety standards , their certification still seems doubtful.

AS-4777 standard , is handling the inverter connected to the grid energy systems and networks in the world. In order to pass Clean Energy Commission (CEC) approved listing of pure sine wave power inverter " must AS 4777.2 and 3-2005 ( or equivalent ) and AS3100 ( or equivalent ) standard , in a suitable test lab to get tested ."

However, in AS4777.1 ( installation requirements, Section 5.3.1 ) , it is clearly pointed out: "Inverter fixed wiring should be connected to the distribution switch a dedicated circuit ." If strict compliance with the AS-4777, which seems to avoid the use of any type of plug and play devices.

Another important issue relates to the power distributor. Before the generator can be connected to the grid ( which includes your house to install solar panels and electricity to the grid ) , to obtain the approval of dealers is a must . This approval is not just a brief telephone or verbal , "Yes, you can do " can decide - but need to have paperwork identified .

In addition, the safety of these individuals has also been improved . Plug and Play with anti- islanding inverter functions and features to prevent individuals continue to provide power during a power outage ( because electricity will continue to supply two seconds ) . If the plug from the power outlet , it can still be released instantly to mention electricity.

Finally, consumers consider installing a plug and play grid inverter , and insurance companies should be confirmed to ensure the proper use of this device does not affect the home insurance coverage , especially as a DIY project .

While in theory is a great idea , but it's these potential problems have led some people to use plug and play inverter concept.
