Solar power enters the homes of ordinary people
In Japan, it can often be seen that many Japanese-style residential houses are covered with blue solar battery panels, and when the weather is fine, the sky is blue and the sky is silent, telling people silently that solar power is entering the homes of ordinary people. According to statistics released by the Japan Solar Power Association, solar cell shipments in the domestic market in Japan reached 99.192 million kilowatts in 2010, which has doubled in the second consecutive year. Among them, residential solar cell shipments were 803,470 kilowatts, an increase of 87.3% over the previous year.
At the Osaka World Expo Memorial Park, there is a "Life and Life Hall", which was once the office building of the Osaka World Expo in 1970. It is now a place for propagating new life ideas and forcing new life styles. The most striking feature of the museum is the residential model combining solar power generation and fuel cell power generation. The text on the side describes "from the use of energy to the creation of energy homes" and "dual-use power generation to achieve a low-carbon society." Less than 100 meters away from the "Life Birth Hall", there is also a demonstration residential area named "Trinary House Park" for visitors to visit. There are 46 two-to-three-story Japanese residential areas in the demonstration area, and all roofs are covered with solar panels. The purpose is to make people feel personal about low-carbon life and experience the harmony between man and nature.
After knowing the benefits of solar-powered homes, environmentally conscious Japanese people will start from me when conditions permit, and make their own contribution to environmental protection. For this reason, solar energy-saving energy-saving homes are increasingly favored in Japan. A staff member of a company in Osaka laid a solar panel with a power of 3.4 kilowatts on the roof in June last year. In addition, a solar thermal heating template was installed. When the weather is not good, it will not be able to send electricity. This family of three will also buy electricity. From July last year to January this year, the electricity bill is 40,000 yen. However, since November 2009, the power company has implemented a “fixed price purchase system†to purchase household surplus solar power at a price twice that of ordinary electricity prices. 56,000 yen, in addition to the cost of buying electricity, actually earned 16,000 yen.
Many Japanese real estate developers are developing energy-saving homes. Sanyo HOMES launched a solar home system installation in 2008 and won the Ministry of Economy, Trade and Industry's New Energy Award. Sekisui Huse Corporation sold 6,000 units of solar-powered power generation from February to December 2009. The integration of solar cell panels and roofs looks very beautiful and is well received by home buyers.
The Japanese government has taken a variety of measures in support of residential solar power generation.
The first is to provide subsidies for the installation of solar cell modules in residential buildings. The solar-powered 1 kilowatt device requires about 500,000 yen, and each family needs about 3 to 4 kilowatts of devices. In order to reduce the burden on families, the Japanese government has subsidized 70,000 yen per 1 kW of equipment since January 2009. In addition, there are other subsidy systems for local government agencies. In 2012, the Japanese government will implement a new purchase system and expand the scope of purchases to include hydropower, wind power, and geothermal power.
Followed by increased efforts to support scientific research and reduce the cost of solar power generation. In 2009, 600,000 yen per kilowatt of solar power generation device was reduced to more than 500,000 yen in 2010. The Japanese new energy industry technology development organization published a white paper in July last year, saying that by 2020, the cost of solar power generation equipment will be at present The basis for the decline is half, so that each household can use solar power to make it more economical and completely clear the obstacles for universal solar power generation.
The outlook for solar homes in Japan is promising. According to the calculation of the Ministry of Economy, Trade and Industry, by 2020, the number of homes that install solar modules will increase by 500,000 each year, and by 2020 renewable energy will increase by 32 million to 35 million kilowatts. Carbon dioxide emissions will therefore be reduced by 1.8% to 2.2%, and the related market scale for the production of solar power generation devices is expected to reach 10 trillion yen. More importantly, solar power is the strategic focus of Japan’s economic growth. If it can continue to maintain its leading position in the world by improving its technological level and reducing costs, it will occupy a more favorable position in the fiercely competitive global market.
