Market diversification initial victory JA Solar counterattack

Throughout the solar Photovoltaic Panels industry trough, JA price once fell below $ 1, facing the danger of being delisted. Not self-revolution is no way out, JA management innovation in the internal set off a storm, by the development of new technologies, the development of emerging markets, and control of financial risk to become an industry leader, will upgrade to the current price of $ 8 or more.

Change the world energy map was Chinese solar PV industry giants dream, but in 2011 began the second half cold wave struck them by surprise, a new vision of limitless energy revolution process marked by a "pause."

Layoffs, bankruptcy, delisting enveloped the Chinese solar PV industry, the majority of small and medium enterprises are in photovoltaic production or semi-shutdown state. How to find a sustainable development of the solar photovoltaic industry way of existence?

Winter in the industry and the EU "double reverse" investigation under the shadow of JA contrarian growth, the industry's Star of Hope. This year, a quarterly gross margin of 6%, compared with -4.6% in the fourth quarter increased by 10 percentage points. In a quarterly publication of the next day, JA Solar shares rose 70 percent, and led the entire solar sector rebounded sharply, which undoubtedly is in winter in the photovoltaic industry add a fire.

2012, JA and where the Crystal Dragon Group sales revenue of 19.5 billion yuan, net profit of 168 million yuan the whole group. According to Solarbuzz research report, 2012 JA module shipments ranked eighth in the world, compared with 2011 increased substantially by 7, to become the world leader in the fastest-growing component.

The same was in the industry cliff JA, why can achieve contrarian growth?

JA share price had fallen to less than $ faced delisting cliff, has been focusing on photovoltaic solar module industry and JA started by semiconductor silicon crystal dragon Group's parent company did not retreat, the future of the solar photovoltaic industry is their biggest bets . Instead, the harsh environment of outer Forced JA carried out a management revolution, the core technology, emerging markets, financial management to be effective.

According to public information, JA 2010 shipments of 1.46GW, 2011 Linden 1.69GW, 2012 is expected 1.7GW. According to IMS and Solarbuzz research institutions and other international authoritative industry research report, JA 2010 and 2011, global production of crystalline silicon solar cells ranked first, in 2012 the global top two. At the same time, JA has been successfully realized main business components from the battery to the transformation of 2012 assembly shipments accounted for 55% of total shipments.

Wenduo photoelectric conversion rate of technological innovation champion

EU's "double reverse" investigation after the settlement, JA parent Crystal Dragon Group Executive Vice President Guer Ying said with deep feeling, China's photovoltaic products in the EU market, the selling price is around € 0.52 per watt. Under the agreement, the minimum price increased to € 0.56 per watt, the price advantage is obvious, you want to keep the market, expand the market, we must rely on the quality and technical victory, the same product, you must have a higher photoelectric conversion rates.

JA photoelectric conversion rate is to defeat the enemy killer.

August 1, JA announced that the company developed polycrystalline silicon solar cell conversion efficiency of entrepreneurial circles new record, up 18.3 percent, higher than the industry average conversion efficiency improved by one percentage point absolute value, costs can be reduced by 5% to 7%.

JA JA CTO Yong technology for confident, solar photovoltaic cells is JA's traditional strengths, high technology content. With the exception of the United States SUNPOWERD back electrode battery technology and low magnification converging technologies, and Sanyo's HIT technology, JA is a global technology leader. The first two techniques are costly, can not see the prospect of decline. JA successfully developed a number of cutting-edge technology industry, including two printing technology, Cypress technology, Hirohide technology, times show technology, MWT technology and black silicon technology, has applied for 147 patents, of which 63 have been obtained national patent Board authorized.

JA adhere to introduce new products and maintain the photoelectric conversion rate leading level, even in the most difficult times always maintain R & D spending this year in order to ensure competitive products, investing $ 120 million grant to upgrade the product. Currently, JA Solar Cell Research Center developed two polymorphic techniques optical conversion rate more than 18%, three kinds of single silicon photovoltaic technology more than 20% conversion rate. Which has two technology products onto the production line. And most of the enterprises producing monocrystalline silicon solar cells and solar cell conversion efficiency has to remain at about 17.3% and 18.5% respectively.

Yong emphasize a key word is "cost of electricity" and reduce the "cost of electricity" mainly by advances in technology, economies of scale and lower raw material costs. PV industry now has a relatively overcapacity scale unsustainable, raw materials prices have dropped sharply after space has been very small, so the future depends mainly on space technology. JA has maintained a more than six months with the industry-leading strengths, and have sufficient technical reserves. Throughout the solar component, equipment installation costs accounted for 50%, the new technology will not only greatly increase the amount of power per square meter, but also effectively reduces installation costs per watt.

Technology revolution behind the management of innovation. In JA organizational structure, both production and R & D departments are Yong's CTO, in addition to have a dedicated R & D department and the team, in order to form a mass rapid technological production capacity in line at each production base with R & D personnel, production base is equivalent to the production line process R & D department personnel to optimize product performance, allowing seamless integration technologies and products.


Meanwhile, JA with the world's leading suppliers of joint development of technology, because JA solar cell technology is always in the leading level, many suppliers can not meet the requirements. On the basis of the resource sharing, through collaborative research, JA silicon solar cell technology in high-performance, low-cost thin-film solar cell technology and third-generation high efficiency solar cells, and many other aspects of exploration and research breakthroughs in key technologies related the formation of independent intellectual property rights, and the industrialization of research results. At the same time, JA and T? V NEG Company, INTERTEK Intertek Group, the world's most prestigious independent third-party authority to carry out strategic cooperation. JA also with the U.S. Department of Energy's National Renewable Energy Laboratory and other international and domestic leading research institutions and research institutes to establish a broad, in-depth strategic partnership.

Week engineers to answer solar charger Precautions



Market research shows that not only solar charger to charge your phone, it is to convert solar module into electrical energy stored in the battery inside the future, as any form of battery storage devices, mainly for lead-acid batteries, the load is also not only for mobile phones and other digital products, load diversity.

New coating technology mainly to solve the two problems, one is to help solar panels absorb almost all of the solar spectrum, the second is to make solar panels absorb sunlight from a larger perspective, thereby increasing the solar panels absorb sunlight efficiency . Ordinary solar panels usually only absorb part of the solar spectrum, but usually only when direct sunlight absorption efficiency is high, so a lot of solar installations are equipped with automatic adjustment system to ensure solar panels always maintain the most help absorb the sun energy point.

The principle of solar charger:

Solar charger in the sun by converting light energy into electrical energy and stored by the control circuit built-in battery, you can also generate electricity directly to light the mobile phone or other electronic digital products charge, but must be based on the brightness of the sun may be, In the case of the absence of sunlight, and by alternating current into direct current by the control circuit stored in the built-in battery.

Solar cell phone battery charger lithium battery is generally the best should be the lithium polymer battery, safe and high performance. The principle of solar cell phone charger solar energy into electrical energy stored in solar cell phone charger built-in battery, in the need for cell phone charging, solar cell phone charger in the power output of the phone battery will charge.

Solar Charger Note:

1 can not be inter-segment charge light (direct diy solar panels ) about 8 hours, can be filled with built-in battery.

(2) In the summer Do not place the charger inside the vehicle (interior temperature is too high). Affect battery life

3 Do not separated by glass on the charger, charging poor results.

4 must be charged under a bright light in low light (Light1) lights represent only detect light, does not mean that has been in charge (as in indoor lighting lamp), so do not be charged in low light .

5 As shipped, the power contained within each of the charger is inconsistent, so the initial charge or discharge time used will be different.

6 Do not use corrosive solution to clean the machine, in order to avoid damage to the product.

7. Resale of the product into the fire, so as not to cause an explosion.
