Japan's photovoltaic power generation policy and photovoltaic facilities

Japan has basically no natural energy, but aims to be a world leader in environmentally friendly energy.

Japan has launched the “New Sunshine Plan” in 1992, and at the same time promulgated a new net electricity metering law, which requires the power sector to purchase excess photovoltaic power at commodity prices and implement a subsidy policy. The average annual growth rate of Japanese residential photovoltaic roof systems in the past five years is 96.7%, and the Japanese government plans to install a total of 4,820MW in 2010.

The Japanese government stated in late June 2008 that it would implement subsidies and tax incentives in 2009 to encourage households to adopt solar power systems. This policy will include halving the cost of Japanese households purchasing solar power systems from major solar module manufacturers. These companies include Sharp Corporation, Kyocera Corporation and Sanyo Electric Corporation. The Japanese government also issued new regulations in 2009, requiring oil and gas companies to use certain clean energy sources, such as biofuels, to produce petroleum products and provide gas from 2010. These measures are expected to help reduce the cost of solar power generation systems. About 2.3 million yen (US$21,440) is now reduced to 1.1 million yen in 3 to 5 years. The start-up plan includes the installation of solar panels in more than 70% of new homes by 2020, as a measure to strongly promote the use of new energy.

The Japanese government implemented a new system for purchasing surplus power from solar equipment installed in homes and schools on November 1, 2009. Power companies purchase surplus power at a price of 48 yen/(kW.h). The new price is twice the original price. Times. The implementation of the new system will promote the popularization of solar power generation equipment and help reduce greenhouse gas emissions. However, the power company will pass on the increased cost to the electricity bill, and users who have not installed solar power generation equipment will bear a certain degree of cost, which will increase the national economic burden. So far, Japanese power companies have voluntarily purchased unused electricity from homes, schools, etc., where solar power generation equipment is installed, at a purchase price of 24 yen/(kW.h). The new system doubles the original purchase price and also stipulates that power companies have the obligation to purchase surplus power within 10 years. At present, if new houses in Japan are equipped with solar power generation equipment, the average cost per household needs to increase by about 1.8 million yen. According to the estimation of the Ministry of Economy, Trade and Industry, the income from the sale of surplus electricity and the Solar power generation equipment has the effect of saving electricity costs, so the cost of installing solar power generation equipment can be recovered in about 10 years. Therefore, the purchase price of surplus power has doubled this time, which will undoubtedly help people who are considering installing solar power generation equipment. The effect of the agent.
