项目摘要

(1) The research examines the feed-in tariff scheme (hereinafter, it is written as FIT scheme) for photovoltaic electricity (hereinafter, it is written as PV electricity) in Germany. a) The German FIT scheme provides very high tariffs which enable the annual income from PV electricity sales to be around 10% in the average PV system price. The German FIT scheme has a 6 times greater effect in increasing PV installation than Japan's government subsidy scheme. b) The cost of FIT remuneration per kWh is a very small percentage of the electricity price for households. c) The Germany's privilege scheme increased the EEG surcharge for non-privileged electricity consumers to 0.17 cents per kWh in 2009. In many cases, the privileged electricity-intensive businesses are manufacturers in the fields of steel, metal, chemical and small-scale businesses.(2) The research analyzes the costs and benefits of feed-in tariff schemes with 20 years remuneration for residential PV electricity in Japan. This research proposes a scenario in which 18.5 GW in cumulative capacity of residential PV is installed by 2020. The experiences from the German FIT scheme show that PV tariffs must be sufficiently high to enable PV power producers to have an annual profitability around 10 %. When the price of crude oil continues to increase at 3%/year from the level of $80/barrel, around 30 to 40 % of the FIT cost for remuneration could be paid off through the reduced expense for oil imports. The privilege of FIT surcharge for electricity-intensive businesses must be given to a business which purchases a large amount of electricity from the grid.

（1）研究研究了德国的光伏电力（以下简称其为拟合方案）（以下简称这是适合方案）（以下简称该方案）在德国。 a）德国拟合计划提供了非常高的关税，这使得PV电力销售的年收入在平均PV系统价格中约为10％。德国拟合计划在增加PV安装方面的影响是日本政府补贴计划的6倍。 b）每千瓦时的适合薪酬成本是家庭电价的一小部分。 c）德国的特权计划在2009年将非特权电力消费者的脑电图附加费增加到每千瓦时的0.17美分。在许多情况下，特权电力密集型业务是钢铁，金属，化学和小型企业领域的制造商。这项研究提出了一种场景，即到2020年安装了18.5 GW的住宅PV累积能力。德国拟合计划的经验表明，PV关税必须足够高，以使PV Power Sustomer的年度利润率约为10％。当原油价格从每桶80美元的水平持续3％时，大约30％至40％的薪酬成本可以通过减少的石油进口支出来支付。必须向电力密集型企业提供适合附加费的特权，该业务必须从网格中购买大量电力的企业。
