Photovoltaic energy was thought to be expensive and to lack stability for usage on a large scale. However, the situation seems to be changing these days. There are buildings in cities equipped with photovoltaic array. Home manufacturers advertise houses with solar panels that could decrease the purchase of electricity.
Young people use solar panels and batteries for outdoor activities.
In order to figure the current situation of photovoltaic energy use in Japan, we are going to search relevant materials on the Internet and summarize them. In 1994, the government adopted the Basic Guidelines for New Energy Introduction to accelerate the introduction of new types of energy that are abundantly available and impose less burden on the environment. Although solar power generation has been greatly improved, it is still more expensive than conventional ones. A person planning to install a PV power generation system in a private housing, a housing complex supplier planning to install a PV power generation system, and a local government in lieu of persons interested in system installation can apply for the subsidy. In FY1998, subsidies were given to 8,229 cases, 31.8MW, 14.7 billion yen in total.
