Japanese companies have invested solar-related industries

On the solar view of the development process of countries in the growth and decline, the mid-1990s onwards, the original United States influence in the global production of four into a home, and gradually squeezed by the Japanese, as in 2004 Japan in the global solar photovoltaic market has possession of five into production , The United States holds only 11.63% of market share in Europe continued to maintain the 2-3 percent of the city of proportion.
Japan's solar power (PV Cells and Modules) output again at a record high in 2000 of about 115MW, the output value reached ¥ 76,960,000,000; 2001 annual output growth of 21.1 percent reached ¥ 93,200,000,000 to Japan in 2002 solar cell industry will to 26.4 percent annual rate climbed to ¥ 117,800,000,000. PV Cell Japan's major manufacturers, including Sharp (2000 global market share 17.5%), Kyocera (all


The ball 14.6 percent market share), Sanyo Electric (5.9 percent global market share), Mitsubishi Electric (4.2 percent global market share), etc.; recent Japanese solar cell manufacturers have much to carry out the expansion of production plants, for example, Sharp plans to build in 20mW production capacity of factories to manufacture many fine silicon-based solar cells; Mitsubishi Heavy Industries is also intended to invest ¥ 5,000,000,000 Factory production of the construction of new amorphous silicon solar cells, starting in 2002 the introduction of new products, In addition, Sanyo Electric plans to At 5 years will be amplified to an annual production capacity of 200MW, its one of the priorities of amorphous silicon. In addition, the Sanyo Electric in October 2001 in implementation of the energy conversion efficiency as high as 21% of the solar cell.

Japan in the 2004 fiscal year, against six major PV photovoltaic project budget to support the total amount of money that is as high as 240 million U.S. dollars, compared to Taiwan in 2004 Taiwan GDP (GDP) of 0.07%. 2004 JAPAN new solar photovoltaic system equipment capacity of 272MW (megawatts), in 2001 are 2.5 times, from 1994 until 2004 the cumulative generating capacity had reached 1.1GW (MW). In 2005 by 70,000 sets of PV systems, with an average capacity of 3.8 to 4 kW peak, the additional generating capacity will reach 330MW, over 21.3 percent growth in 2004.

Japanese Economy, Trade and Industry, will be in 2010 of new energy generating capacity for the use of goal setting 12.2TWh, then the national electricity supply will account for 1.35 percent ratio. In order to achieve the purpose of promoting industrial technology, Sunshine planned technical development planning as shown in table 3. Pre-1997 to the crystallization of silicon-based solar cells, since in 2000, then focused on the film, high-efficiency solar cells, solar cells in recent years in part, then the direction of advanced solar cell technology development, and systematic part substantial import common basic technology development, towards the regeneration, re-use and assessment of technological development.

And market promotion of the establishment of a new 1993 Project Sunshine (New Sunshine Project), 1994 New Energy Foundation (NEF) grant individual residential solar photovoltaic systems costs, and lowered the amount of these grants every year. The Japanese government grants for residential solar power generation system used (maximum output 10KW) by 1994 per KW 90 million yen fell to 2001 ¥ 120,000; its grants include: solar cell modules, planes Units, follow me, DC switch, Inverter, protection devices, power generated, the surplus electricity to sell electricity, the wiring / wiring apparatus of purchase / installation / project related costs; plus "Net Metering" incentives, that is, the population remaining after PV power generation can be incorporated into the power grid, and finally the people give the power companies to pay the electricity grid for their electricity use after deducting the cost of electricity back; after because of the gradual expansion of market demand and a maturing industry, the Government grants dropped to 2003 KW grants each year has dropped to ¥ 90,000, in 2005 and fell even further to ¥ 20,000, but the plant did not scale by increasing rather than reducing. This is because in the past, manufacturers have substantial production economies of scale advantages, effectively reduce the cost of PV systems and the development of prices, the future when the solar cells and building materials after the integration of Tatsu, PV system costs are expected to be installed at each from the current peak kW ¥ 670,000, down from 3-500000


Between the Japanese yen. In other words, the lowest unit cost will be less than 90,000 yuan NT. And hope that the price of future products will be gradually transferred to the market mechanism to decide.

Although the Japanese central government's subsidy policies have been close, while Japan's solar energy association (JPEA) is still full of confidence that the Japanese concept of great importance to environmental protection, the cost is more important than price, it is expected PV market boom will be able to continued, but the major solar cell manufacturers have been published from 2006 to 2007 capacity planning, the next push in recent days shows that the market growth of the PV power from government to private and corporate. According to estimates JPEA research shows that by 2010 new devices every year there is about 1230MW, the market size of about 4.5 billion U.S. dollars, the cost of solar modules and PV system will generate electricity prices were reduced to ¥ 75-per-watt, 14 yen / KWh, with a view to the traditional with the current energy prices (per kW at about ¥ 15 below) to compete. And from 2010 to 2020, the annual volume of new devices can be upgraded to 4300MW; to 2030 the volume of the new devices will be upgraded to 10000MW, and PV electricity prices fell to ¥ 7 / KWh, while for Japan to create 300,000 job opportunities.

Japan's balance of technology and market development, the success of industrial development to enhance their international competitiveness, and the continuation of the past solar photovoltaic development, to new energy into an independent operating mechanism, Japan's future will be focused on the establishment of international standards, not only to actively maintain technology leadership, and promote Taiwan's economy, but also by adjusting its energy structure, and strengthen national competitiveness.
