Obama re-elected President of the United States. Obama will be in the first term renewable energy industry policy orientation for the core of the "green New Deal" to come and go,power inverter  the U.S. still did not find the way of jump-start the economy. However, Obama hands is a trump card. That is was inaugurated as President barack Obama when not fully pay attention to natural gas into a deep sleep in the United States under the land of energy resources. "Brown revolution" will decide in the next four years the United States and the world pattern.

Obama to push the "brown revolution"


Realize reelection Obama (kyodo)


In the face of the Rocky Mountains on the outskirts of Denver, in Colorado Aurora city (Aurora), in the presidential election in the climax of the July, a general electric (GE) in the United States will delay the construction of the largest solar battery factory news that local residents are disappointed. The project investment of $600 million, is expected to create more than 300 jobs.


GE chairman Jeff immelt now serves as President Obama advisory committee "the White House employment and competitiveness committee chairman, is with Obama that there is a close relationship between a handful of people in the business of. In Obama government set up four years ago, Mr Immelt once repeatedly use said attached great importance to environmental new build vocabulary "green creative (Ecomagination)", but more recently, change in order to "oil and natural gas".


This not only means that the solar energy cell foam collapse, renewable energy industry falling, representing the Obama "green New Deal" mistakes.


Bankruptcy enterprise appear constantly


In 10 years to renewable energy field investment of 150 billion us dollars, create 5 million jobs Obama in 2009 when President put forward the above policy, the policy of President Roosevelt modeled after the war of the implementation of the "franklin Roosevelt's New Deal" was named "green New Deal". Although Japan and other countries then in a certain extent caused environmental investment boom, but the reality is not satisfactory.


"The recipient enterprise almost half may have into bankruptcy," in October the first televised debate between presidential candidates meeting, republican candidate Mr Romney accused the Obama. Although Mr Romney said than actual situation as exaggerated, but not be denied is,grid tie inverter from Obama government subsidies to accept the solar battery manufacturers Solyndra and in the car battery field has the advantages of A123 Systems have successively bankruptcy.


Government aid have ended in failure causes include, (1) the United States energy department says: "and accept than the American enterprise more rich government aid Chinese between manufacturers competition". (2) "IT (information technology) fewer restrictions, energy industry more restrictions. The IT industry business cycle is short, the energy industry and a long" (immelt language) is also difficult to cultivate one of the reasons for the new business.


In the past, the democratic former President Clinton once put forward "information superhighway idea", the revitalization of the IT and network industry, etc., but "green New Deal" but delayed their achievements. President barack Obama has started to make a fresh start.


"All Of The Above (general mobilization)", Mr Obama in The presidential election in energy strategy so called for. Four years ago a to pay more attention to the attitude of renewable energy. Obama said "must use of domestic all available resources", put forward the domestic natural gas and petroleum security development.


One of them is "shale revolution". Due to the high efficiency mining underground page rock gas and oil technology progress, the United States shale gas and shale oil production is soaring. Oil, ratio of dependence on export expected this year from four years ago to 52% lower to about 42%, the lowest level for 20 years. Obama said natural gas production in the world the first American as "natural gas Saudi Arabia".


Forces expand between China and Russia


Obama before taking office more than 10 dollars of American domestic natural gas prices have dropped to a third of the 3 dollars. Obama hope energy cost reduction can promote the United States manufacturing return home, improve international competitiveness. Barack Obama is to go "realistic route",solar panel there is not afraid of the United States, catch up with competitors.

Shown in Figure 2, consisting of Q1, D2, D1 in the figure a protection circuit, wherein D1 (1N4743) to the Zener diode (+13.5 V), D1 and D2 together form a bias circuit of the transistor Q1. R1 is a current limiting resistor of the Q1 tube. Circuitry external charger, such as the maximum threshold voltage of the battery is about 14.4 V, in the initial stage of charging batteries according to conventional undervoltage condition slowly rising start conducting when the battery voltage reaches the breakdown voltage of the Zener diode D1, D1 tube through Q1 tube conduction, prompting A decline in B terminal voltage, set the appropriate parameters to the highest value no greater than 14.4 V battery voltage across. The protection circuit causes the battery when the battery has been filled in the trickle charge state, which makes the battery charging protection function.


When the voltage across both ends of the battery voltage is higher than the solar panels, the battery may produce the phenomenon of reverse charging to solar panels. Once this happens, the solar panel is likely to be burned, causing losses. Thus, the overcharge protection circuit should also include the anti-charge circuit, i.e. by connecting a diode between the solar panels and the battery to prevent reverse charging of the batteries on the solar panel shown in Figure 3.


A solar street lights intelligent control system design



1.2 over-discharge protection circuit


Q2 from the comparator hysteresis comparator circuit has two threshold the voltage: VTHR and VTHL (VTHH> VTHL), a hysteresis area. , The comparator output is high when the battery voltage from the low elevated to VTHH;, the comparator output is low when the battery voltage decreases to VTHL. This time the battery terminal voltage will rise rapidly over the VTHL reach VTHH comparator still output low until after the battery is charging voltage increases to VTHH to output high again. Thus avoiding the oscillation of the circuit, to protect the load and battery.



Comparator positive terminal reflects the sampling of the battery voltage U3, comparator reflected in the negative terminal of the battery is the reference voltage U2. When U3> U2, the comparator output is high, Q1 turns on, Q1 of C is extremely low, Q3 is turned off, the load does not work; When U3


1.3 backup power


Solar panels in the rainy days can not charge the battery to work state, it is necessary to use the backup power supply to the circuit supply backup power using the AC to DC conversion, to convert alternating current to the rated DC voltage value to ensure that the circuit work properly.


1.4 Infrared light control control circuit


The system uses a BISS0001 chip, it is a high performance sensor signal processing integrated circuit, it is accompanied by a pyroelectric infrared sensor and a small amount of external components constitute passive pyroelectric infrared switch with independent high input The impedance of the op amp. The part of hardware implementation of integrated chip BISS0001, Transistor 8050, photoresistor, and infrared sensors can be selected to design. Infrared sensors, the sensors send infrared signal processing feedback to control the end, after the internal linear amplification, two-way the parcels,grid tie inverter signal processing, delay timing, timing, etc. blockade processing. Its feet 2 output high so the transistor 8050 is turned on, driving the relay pull-K, and then controlled by the relay contacts controlled object. Here triac relays can be replaced.


A solar street lights intelligent control system design


Operational amplifier OP1 pyroelectric infrared sensor output signal for the first-stage amplifier, and then the second stage amplifier coupled to the amplifier OP2 by C3 processing via a bidirectional amplitude discriminator voltage comparator COP1 and COP2 detection valid trigger signal the Vs to go start delay timer output signal Vo by transistor T1 zoom drive relays to switch on the load. Wherein, R3 is a photosensitive resistor, is used to detect the environmental illuminance. As lighting control, if the environment is brighter, the resistor values ​​for R3 will be reduced, so the 9-pin input is held low, thereby blocking the trigger signal Vs. SW1 is the operating mode selector switch. When SW1 and 1 end connectivity, the chip in a reusable trigger work; SW1 and 2 end connectivity, the chip is not repeated trigger work. Diagram, R6 can adjust the size of the amplifier gain, artwork selected 10 K, and actual use can be used 3 K, can increase the gain of the circuit to improve the circuit performance. Output delay time Tx, triggered by external R9 and C7 resize blockade time Ti by external R10 and C6 resize, R9/R10 with 470 Ω C6/C7 can choose 0.1 V.


2 innovation


(1) Battery over-discharge protection circuit is simple and flexible to use. Simply select a higher supply voltage comparator, and can be applied to any of the voltage level of the circuit; simply by changing the resistance value can be set arbitrarily turned on and shut-off threshold, and thus can have a wide safety range.


(2) In the control system, the lighting power supply and chip operating power separately, the battery power supply shunt regulator handle separately, in the use of the small power relay automatically select the appropriate voltage, a small voltage is supplied to the chip work, a large voltage supplied to the lamps lighting , to avoid the use the same large voltage supplying the generated power loss. Lighting circuit at the same time, avoid the use of larger power transistor switch, but the use of SCR.


(3) The design of backup power, continuous extreme weather conditions, the battery power runs out, the lack of timely charging backup power inverter  supply, you can automatically turn on the street lights work properly.


3 Conclusion


The solar street lighting intelligent control system design, urban environmental protection, energy-saving lighting, ease the tension in the case of conventional energy sources have positive significance. The entire system runs are automatic control, the working principle is simple, easy to install, reliable technology. Scope: on the one hand, focus on mining roads, landscape lighting, as well as possible future promotion of solar system area network powered applications, technology and market promising. On the other hand, in certain occasions obvious (islands, scenic hilltop, remote locations, etc.), application advantages, including demonstration and application of positive significance, so the study makes sense.

Peng Fang, JA Solar Holdings Co., Ltd. CEO. In the the Best Solar high-tech company as executive president from 2008 to 2010, he is one of the largest semiconductor manufacturing company, Hua Hong NEC Chief Executive Officer, and held various technical and management positions in the U.S. Silicon Valley, Applied Materials and AMD. Director of the US-China Green Energy Council (UCGEC) SEMI PV Advisory Board members,power inverter  and has served as president of the Santa Clara Electronics Engineers. University of Minnesota, Department of Electrical Engineering master's or PhD, University of California, Berkeley post-doctoral researcher.

Finance the new Tencent Joint Publisher] (fiscal reporter Zhang Hong,) the European Union, the United States, China, the world's top three trade between economies is the field of photovoltaic industry has sounded a trade war drums of war. Following the U.S. Department of Commerce announced the preliminary results of Chinese enterprises to anti-dumping, anti-subsidy, as China's most important export market for the EU anti-dumping investigation was launched in September this year, the Chinese PV companies. International market took a plunge, the domestic industry is also due to the rapid expansion of the predicament facing large-scale production capacity surplus. Industry losses, layoffs and other news reports.

China's solar industry is able to weather the storm? The end of September 2012, in Geneva, Switzerland, Geneva China High-level Forum on JA Solar Holdings Co., Ltd. CEO Peng Fang as a representative of the Chinese solar energy enterprises, given the still very positive information. He told the participants, policy support and industry after years of development, the cost of solar power has been a significant decline in the next two to three years to reach grid parity. The timing of promotion and application of large-scale solar power generation will be mature.

The new fiscal reporter interview in Geneva Peng Fang. He pointed out that the response to the external trade disputes, China's solar industry on the one hand the need to diversify the export market, the more important is the development of the Chinese domestic market. This requires both the enterprises themselves ready, and also asked the Government to recognize the laws of the market, "the tube the tube should not pipe do not control." Chinese solar industry to go in front of the world solar industry development,
solar panel  this is a historic opportunity "Do not hit, just continue to build and improve the industrial environment in the reform and opening up.

The the new fiscal reporters: European companies recently initiated anti-subsidy complaint Chinese PV companies, one big reason is that Chinese enterprises to obtain low-interest loans of the State Development Bank. You respond?

Peng Fang: U.S. dual investigation of Chinese enterprises is to say, the State Development Bank of China since 2010, some Chinese enterprises total out of the $ 45 billion credit line. There is some misunderstanding. Western media translated as "credit line" this $ 45 billion, but the western bank credit line loans ready to be used at any time, CDB $ 45 billion just a MOU (memorandum of understanding). This is not the same as the process of the China Development Bank and other bank loans, it is to look at the enterprise in the next five years, ten years of investment plans how enterprises usually reported a more radical plan, such as $ 5,000,000,000, a $ 3 billion investment. CDB signed the MOU with the enterprise does not have the force of law, and say that it is a pre-qualification (pre-qualification) or it is to understand the business in the future intention behavior. So this is a misunderstanding of a different culture and working methods. Because the Bank of China may long internal working procedures that it early to understand what customers see how they plan.

Enterprises signed the agreement but also a marketing tool, qualified to CDB loans; the CDB signed this agreement, said the plan. But the actual final loan process,
grid tie inverteris still to be business as usual by the commercial audit - project where and how to return on investment, what is to mortgage interest to talk about how. Our company actually signed an agreement of $ 4.5 billion, but so far has not used any money.

 March 20 this year, the U.S. Department of Commerce announced the "double reverse" punitive tariffs on Chinese exports of solar photovoltaic products preliminary ruling tax rate, at that time, "the use of the battery cell production outside the mainland of China board is not within the scope of taxation. On October 10, the U.S. Department of Commerce will announce the final ruling rate to industry estimates, when "blocking" loophole does not rule out the Ministry of Commerce. For Hebei PV giant, which means less of a roundabout option. In addition, the U.S. countervailing duty also raised the possibility exists.

Announced in March by the U.S. Department of Commerce anti-dumping and countervailing punitive tariffs up to 35% for most of the Chinese power inverter companies.

The "double reverse back 90 days Tariffs levied of Hebei Baoding Yingli Ning Jinjing Australia photovoltaic giant, already suffer losses of several hundred million dollars, to further expand the operating loss.

However, the preliminary ruling tariff of 35% of the "dual" is not nailed. Under the program, the U.S. Commerce Department will make a final.

Rate for the "dual" preliminary ruling, the U.S. politicians, businesspeople, later disputed sound. Reporter noted that, by the end of June, the U.S. Commerce Department spokesman Tim Truman said the U.S. media, in the survey, the Commerce Department found that Chinese PV companies also get other government subsidies, the Commerce Department will modify the preliminary countervailing duty tax rate.

According to an internal document of the U.S. Department of Commerce on June 22, the Wuxi Suntech facing countervailing duties from 2.9% to 3.44%, Changzhou Trina Solar transferred to 5.81% from 4.73 percent, due to other Chinese PV exports face countervailing duties, according to Suntech and Trina Solar average calculated from Yingli, JA Hebei photovoltaic enterprises, will also face higher countervailing duties.

Also in March, the U.S. Department of Commerce announced preliminary "dual", the Chinese people in the industry soon found a "loophole" --- "dual" punitive tariff does not apply to solar panels outside Mainland China solar cell production in China Mainland . This means that Chinese companies can set up production plants in foreign battery, or purchasing foreign battery, then the labor cost advantage in the Chinese mainland, the welding assembly of solar panels.

The reporter noted that some domestic photovoltaic enterprises senior told the media that will take advantage of this provision seeking to reduce the loss of export profits of U.S. "double reverse".

However, this "loophole" soon attracted the attention of the U.S. solar industry as well as members of Congress. The end of September, eight members of Congress to pressure the Obama administration to "double reverse" loopholes blocked China PV, that is, at the same time for Chinese enterprises to take advantage of taxation of foreign cell production of solar panel.

It is worth mentioning that members of the US-led pressure to the Obama administration Luo Wade and Jeff Bathroom From both of them from Oregon. It was German solar giant Solarworld, located in Oregon's U.S. subsidiary, to provoke a "double reverse" survey of the U.S. PV exports to China.

The face of pressure from members of Congress, the U.S. Department of Commerce officials said, will consider a "loophole" announced that the final award rates.

After the U.S. Department of Commerce announced that the final ruling rate, the U.S. International Trade Commission will be based on the Chinese PV exports is injurious to the United States and the industry, "the survey results, ultimately decided by vote whether to impose a" dual "tariff. The agency has not yet announced the polling date, but is expected in November.

It is reported that the U.S. International Trade Commission has begun to hold U.S. PV companies to expand the "damage" to the investigation.

If the United States International Trade Commission, the final judgment, the China PV exports did not harm to the United States PV industry, the "double reverse" tariffs will be canceled before Chinese enterprises prepaid punitive tariffs will be refunded

Europe has been for many years in the global photovoltaic market dominant, but to the rest of the world countries also obviously have a lot of potential for growth. Due to the local and global energy demand drive, the fastest photovoltaic growth in China and India will continue to put on, the second is southeast Asia, Latin America, the Middle East and north Africa countries. Sunbelt national pv potential can be without financial support similarly hereinafter diesel generator competition, and to 2020 May reach 60 to 250 gw area, to 2030 260 to 1100 gw. As photovoltaic power inverter industry in 2011 experienced sooner than expected to cost down, in the future ten years or even more countries will see photovoltaic more and more competitive. In 2011, other parts of the world new photovoltaic installation have accounted for 7.7 GW, compared with 3.3 in 2010 GW has more than doubled. China in these countries in 2.2 GW installation quantity rank first, the second is the 1.9 GW, a third for Japan 1.3 GW. It is expected that all these countries will continue to maintain growth in 2012. In 2011 Australian photovoltaic market expanded rapidly, but its growth in the short term by political conditions. Canada’s expansion speed slower than expected. India powerful market potential seems to have begun to soar in 2011, there were 300 mw of photovoltaic installation.

Outside Europe countries photovoltaic installed the ability to form large contrast. Part of the emerging markets outside Europe in recent years can’t catch up with China, the United States, Japan and Australia installation speed. Three potential of the great country is guiding role, and lead a new secondary market. In addition to Australia in 2011 prosperity and development outside, most countries still in the policy under the control of the forward. Along with the potential gradually released, the photovoltaic installation outside Europe share only increase. At the beginning of 2012, Germany and Italy is monopoly more than 50% of the world installed capacity. But four non-european main GW level solar panel market including Japan, the United States, China and Australia with the top ten ranks.

In 2016 the global pv prospect forecast

In 2011 the global installation nearly 30 gw of photovoltaic system, photovoltaic market began to at the crossroads of development. Is expected to before 2016, outside Europe emerging market growth will not be able to make up for European countries installed drop caused by vacancy, of course, the speculation is based on the next five years market depression, especially in Europe. But the above conclusion in the next few years the probability of occurrence in a have how old? Must consider two main driving factors: one is the existence of the open market can absorb part of the excess supply of photovoltaic system; Another is the evolution of the pv modules and price. 2011 pv industry experience winter is due to the imbalance of supply and demand to pv modules (high demand to be close to 30 gw, but supply about 50 gw). Market weakness promptly absorb inventories and the early 2012 pv product price continues to fall. Market development will be slow to reduce prices again, at least in the short term, if there is no regulatory restrictions, photovoltaic development will be more favorable.

But for most industrial chain link, it lower the cost of the space becomes more and more small. In addition, it has great development potential of the existing market is very limited, because more and more countries began to implement registration and total amount control. With the development of the slowdown in Europe speed, further rapid falling prices could lead to all over the world factory closed. This kind of state change depends on the European grid tie inverter market changes, and the decision maker’s ability, to ensure that the market can be maintained at an acceptable level. In the policy drive, the European market will be in the next few years stable in about 20 GW ~ 25 GW level, with the market outside Europe worked out. At this development, the market may be in 2016 more than 75 gw, with two-thirds comes from new market outside Europe.
