RENEWABLE ENERGY CERTIFICATION简称REC.
        而碳排放能源公司每排放1吨CO2就必须向可再生能源公司购买1个REC.否则要罚款.

        Nowadays in Australia market, the price of each REC is between 30 to 40 AUD, in 2011, the price of REC will be locked to 40AUD.
        现在在澳洲市场, REC的市场价大概为30~40AUD之间.

        In case the REC is not purchased by CO2 generated company, the fine is 65AUD/ton of CO2, therefore those companies will buy REC. in this way, the solar industry is pushed. 2011年, REC的价格会被锁定为40AUD.
         而每排放1吨CO2, 如不购买对应数量的REC的情况下, 会罚款65AUD. 所以碳排放能源公司会主动购买REC, 从而贴补和推动光伏行业的发展.

         Till 2020, Australia promised to have 20% energy as renewable energy, while they have only 5% now.
         2020年澳洲必须有20%的能源来自可再生能源, 而现在只有不到5%.

         1 home system=3000W =1500w+1500w
         按照一户家庭安装3KW屋顶系统为例,第一个1.5KW系统可获得五倍的REC,第二个则按照1倍计算。每个REC交易约合

         3KW system à 28~30 REC*5 +28~30 REC=168 ~180 REC
         38-40澳元。 即:6*(28~30)*(38~40)AUD/REC

         168~180 REC=AUD$ 6720~AUS$ 7200
         即:最少收益6720澳元,最高收益7200元
