From the 58's of 20th century, the man-made satellite that the U.S. launches just utilizes solar cell as the source of energy. During 20th century energy dilemma seventies, countries in the world are allowed to perceive the importance of energy development. Within 1973, there occurs oil crisis, people start the application of solar cell to transfer in general people's livelihood purposes. In countries such as the U.S., Japan and Israel, use solar energy equipment in a large number, more advanced towards business-like target. In these countries, the U.S. sets up solar plant maximum in the world in nineteen eighty-three in California, and its generated energy can be special up to 1,600 myriawatts. The other countries in South Africa, Botswana, Namibia and south, Africa also set up special project, encourage remote area, rural area to install the solar cell power generation system of low cost. And carry out first-elected Japan of the most positive country of sun power generating. Within 1994, Japan implements subsidy incentive method, promotes " city's electricity parallel connection type sunlight electrical energy system " of each household 3,000 watts. In 1 year, the funds of government subsidy 49%, later subsidy was successively decreased year by year again. " city's electricity parallel connection type sunlight electrical energy system " is when abundance at sunshine, providing electric energy to oneself load use by solar cell, if there being unnecessary electric power, storing separately. When generated energy is not enough or does not generate electricity time, required electric power is provided by electric power company again. By 1996, there were 2,600 family device solar power systems in Japan, and installing total volume has had 800 myriawatts special. After 1 year, having had 9,400 family devices, it is special that the total volume of installing also reaches 3,200 myriawatts. Along with the system of the surging of environmental consciousness He government subsidy gold, estimate the demand of Japan's household's solar cell, also can increase rapidly.
