Japan plans to provide low-interest loans for residential rooftop solar

According to the Nihon Keizai Shimbun reported that the Japanese Ministry of Economy plans to borrow residential roof space for solar energy development companies to provide low-interest loans. The newspaper quoted Trade Minister Toshimitsu Motegi as saying that the province plans to Development Bank of Japan and other government financial institutions to provide loans. The newspaper revealed that, Motegi will be held tomorrow on industrial competitiveness conference to announce the plan.

Under the proposal, these companies will sell the family installed photovoltaic inverter on the roof generate electricity. Homeowners will receive 10,000 yen per year (about $ 97) to 20,000 yen for rent. Merfert: Middle East showing the unique business challenges, and the two most common problem is that the performance of the components in the environment of high temperature and stains. If you are already in Dubai to spend a summer day, or witnessed the dust storms of the central region of Saudi Arabia, you will see the technical performance of these products will have an impact.

On the temperature of the photovoltaic power generation system performance impact on the temperature coefficient of the photovoltaic solar cell panel modules, it shows the temperature dependence of the power performance. As the operating temperature increases, the efficiency loss of all semiconductor devices have become more serious, however, compared with the conventional silicon technology, because cadmium telluride low temperature coefficient, which provides us with a significant advantage in energy production. Cadmium telluride temperature coefficient of -0.25% / ˚ C, and a temperature coefficient of silicon -0.45 to -0.5% / ˚ C

. Photovoltaic power plants to generate electricity only in the sunlight, the typical components of the operating temperature range of 50-70 ˚ C, much higher than test standards 25 ˚ C. This is a typical hot desert climate means that every watt of 9% additional energy output. The dust can also affect the performance of the PV system. The dust deposition factors affecting the PV modules is well documented, our on-site measurement stains. The device also been strictly sandblasting, environmental sealing, corrosion resistance test.

While we do not need to clean the U.S. PV array, where each of precipitation fouling can alleviate the loss. However, in the Middle East, India and parts of Africa, we do need to provide cleaning solutions according to the availability of water. As a source of electric power generation, compared with other techniques, the PV water consumed less. We have been committed with a dry, mechanical solutions to minimize the amount of water used.

Solar industry capital expenditure in 2013 will hit a 7-year low

Although the photovoltaic supply chain global capital expenditure this year is expected to fall to its lowest level since 2006, but there are signs that investment downturn has bottomed, equipment purchases may soon rebound. According to the information and analysis provider IHS PV manufacturing and capital expenditure Tools, 2013 PV business capital spending will decline from $ 3.6 billion in 2012 to $ 2.3 billion, down 36%.

The expected decline in the 2013 capital expenditure of $ 2.4 billion in 2006 to its lowest level since. This also marks the market decline in 2011 after peaking the second consecutive year, the the 2012 Photovoltaic Panels industry spending plummeted 75%. However, capital expenditure is expected to rebound in 2014, an increase of 30% to 30 billion U.S. dollars. The photovoltaic business chain enterprises have been reduced capacity utilization, production line is idle in the past year and a half, "IHS solar analyst Jon-Frederick Campos said.

PV companies have been doing, trying to cope with excess capacity, alleviate the decline in average selling price pressure caused by this phenomenon in 2012 and so far in 2013, new manufacturing equipment spending fell sharply, however, as prices gradually stabilized, and some PV market manufacturing recovery, indications that the decline in capital spending may be coming to an end. "

2012: Solar Cataclysm 2012, the solar panel industry has been to speed up production, many companies focus on to achieve higher efficiency cells and modules. As a result, a plurality of steps in the manufacturing process increases.

However, this results in the increased capital expenditure, followed by a rise in operating expenses. Later, overcapacity, oversupply and prices plummeted holding the market center stage of the period of the past 18 months, companies suddenly have to reduce manufacturing steps.

At this stage, the cost reduction can also become support weak Margin key. Not according to this company eventually went out of business closed down. Solar cycle For now, the worst case seems coming to an end, there are indications that the decline in capital spending has bottomed out. Spending is finally expected to rebound in the short term, the industry will subsequently pick up. For example, in the past quarter, Latin America, the United States and the Asia-Pacific region a new production base, production also increased.

Sometime in the recent industry will come full circle back to the beginning again, "Campos said. "The solar market has experienced booming, and then because of the rapid success of their own suffering but once the dust settles, the industry will be operating, financial and technical aspects become more powerful. Remainder of the year is likely to determine which will retain a large market share and consolidate its position as the industry leader. "

Leading Innovation in solar demand

With the "Renewable Energy Law" was promulgated, the solar water heater to further the use of solar thermal highest degree of commercialization, the most common technology. Although there are problems, but the advantages of solar water heaters in both energy-saving and environmental protection, enough to be respected by unabated If these problems can be a good solution to will no doubt be another huge popularity of solar water heater promote.

   The solar industry R & D in the field of solar energy concentrated on studying the ten years, has more than 80 patented technologies include solar applications in one, and has begun to be applied to the full company launched the product, the new multi-functional solar cell water heater. It is completely breaking down existing curing limitations of thinking, all effects, designed for scientific, rational, cost-effective basis.

Including solar vacuum collector element static anti-fouling core technology, thermo-siphon to the intake pipe from the circulation pump core technology, the solar vacuum the component pressure balance pressure to run core technology, adjustable condenser heat collecting element core technology, low voltage self-adjoint heated hot water technology, the glass liner environmental health tank technology, functional modular split solar power inverter water heater technology, solar collectors balanced anti-evaporation preparation of drinking water, the module collectors generating element lithium bromide refrigeration heating building integration technology, photoelectric heat integration sun glass the shell heat pipe technology, concentrating solar glass safety heat pipe technology,

Multi-heat source heat pump energy deployment center technology, automatic float guide to water technology, solar water heater pressurized non-pressure conversion technology, solar multi-effect desalination technology, solar vacuum component anti-cracking thermosyphon loop diversion, the sun building integrated heat pump and floor heating technology, optical thermal conversion of one of the Japanese collector technology.

   Among them, the "multi-functional solar water heater" engine new vacuum collector tube, the nozzle such as insulation glass shape of the mouth, reduced diameter nozzle of the vacuum tube, drag, easy to set snow reflectors abandoned, easily water heater collector area is increased by one third, dynamic hot water; sealing gasket installed in the vacuum tube positioning adjustable nozzle installed on the steps, the top pressure under the action of the vacuum tube tail, so that the water in the water heater seam drilling! The sealed insulation improvement and the increase of the collector area so that the whole collection efficiency increased by 40% or more than the original.

   In addition, a number of constraints for the previously mentioned solutions have achieved a breakthrough, the scaling problem, the vacuum tube absorbing film, glass, water capacitor connected to a high voltage direct current circuit, through cross-blocking capacitance characteristics will be very little power, electrostatic induction negatively charged membrane induces a positively charged glass on the water side of the wall the acidic scale is no longer generated, such as the engine lubrication, power constancy. Use of the the thermosyphon principle of vacuum collector tube anti-cracking cold water deflector shunt the hot and cold water, hot and cold water chamber pressure difference between the water flow acceleration, spewing hot Pentium.

Design principles in the solar vacuum tube insertion anti-Donglie cold water diversion, anti-cracking cold water deflector non-absorbent closed cell elastomer-made, non-toxic, heat resistance, anti-aging, sealed high-strength soft coatinflated or filled with a soft elastomeric material of the tubular body through an elastic bracket mounted concentrically fixed in double glass tube constituting a solar vacuum tube water cavity concentrically in the vacuum tube to the water chamber, there is a gap, the supporting installation having a fixed guide The change in volume caused by the flow and regulation of water, ice conversion elastic contraction deformation of the body.

When winter ice, the vacuum tube from the spout at the icing first sealed, the temperature of the water within the tube is gradually reduced expansion, the temperature of the gas within the antifreeze deflector reduce the pressure decreases. Meanwhile, in the role of the expansion of the water pressure is compressed, smaller absorb the stress generated by the water near zero expansion, to achieve the anti-cracking of vacuum tube.

Solar energy development in the direction of innovation, integration, chain

The seriousness of the energy problem can not be ignored, energy conservation, rational use of energy has forced the development of solar energy and into the fast lane. The application of solar energy will also be extended to all aspects of people's lives, a full range of alternative to traditional energy sources, such as the use of the perfect combination of solar energy and buildings, solar photovoltaic, solar thermal, preparation of the health and safety of drinking distilled water, use of solar energy and lithium bromide combined to achieve the cooling of the building heating, solar desalination.

The development of solar energy industry China's environmental protection cause of energy conservation will play an irreplaceable role, and because of its huge market and production and sales in the international arena has been a high degree of recognition. As the pioneers of the solar controller industry, vigorously develop new energy industry is the historical mission entrusted to us, we have a responsibility as the industry has the obligation and also have the ability to "save" contribution to the force. Based on this, some companies put forward the slogan of self-help industry, and industry self-help should not fight to the conclusion that the "top ten to carve up the world" ending, industrial upgrading should focus on technological breakthroughs, solar water heater problems in each overcome to solve a solar applications will open up a new world!

   Direction of development of solar energy must be combined with building photoelectric hot one, not only as a collector power generation device, but also use as a transparent wall materials, power generation, collector, light, heat, noise, reduce electromagnetic radiation and more aspects of the function. In the future of the high cost of land, residential building roof as greening and leisure rooftop, solar cell will become a shade canopy to prevent direct sunlight, solar power, heating, cooling, life with the perfect combination of building hot water, drinking distilled water system and other functions, achieve diversification of solar product features.

In order to maximize the expansion of the solar market, solar become a renewable and recyclable, circular economy industry, while taking advantage of other energy such as solar and heat pump combined to achieve zero consumption of household energy, the building is not only energy, but to generate electricity, all this is bound to be achieved through innovation.

   Judging from the long-term development, the solar industry will be "innovative, integrated chain" in the form of industry output value of large-scale upgrade.

Through with independent intellectual property core technology, the advantages of integration of the solar industry resources together towards output technology, management, establish standards and to achieve the unity of pace. Product "innovation", we must first overcome the problems exposed in the development of solar energy industry, practical performance standards to meet all the needs of consumers, followed by the formation of the core technology with independent intellectual property rights, rather than pander to foreign technology. It is understood that the creation of the metal heat pipe glass tube and metal heat pipe sealing the original with German technology, but they a lot of improvements of the technology, but still resolved not vacuum leak vacuum.

   For resources "integration" is to focus on domestic solar water heater manufacturers with superior resources, such as high-precision CNC punch press, the quality of vacuum tube production line manufacturers. Currently engaged in the production of solar water heaters up to thousands of enterprise with innovative, practical technology plant are rare, we are to compete on the same level, resulting in the industry's cannibalism.
