在欧洲对华反倾销立案的情况下，外销再度受阻，启动内需的迫切性提升，同时由于系统成本快速下降，光伏发电成本已经降至合理水平，建筑光伏的度电成本已经接近工商业电价。

In Europe to China under the condition of anti-dumping,Export again hindered,Start domestic demand the urgency of ascension,And because the system cost rapid decline,Photovoltaic generating cost has dropped to a reasonable level,Building photovoltaic degree electric cost is close to industry and commerce electricity price.

　　在此背景下，国内十二五太阳能装机容量从21GW 上调至40GW（其中包括1GW 的光热）按照建筑光伏与西部的集中式电站各占50%，的比例来计算，未来四年建筑光伏的市场每年将达4GW 以上，并且随着度电成本的继续下降，光伏发电成本将会低于工商业电价，CMEN（国家能源研究院）认为，届时这块市场将会远超规划。

In this context,Domestic 1025 solar installed capacity from 21 gw Rise to 40 gw(Including 1 gw Light hot)According to building photovoltaic and western centralized power station all accounted for 50%,The proportion of the calculation,The next four years building photovoltaic market will reach to 4 year gw above,And with KWH cost continue to fall,Photovoltaic power generation costs will be lower than industry and commerce electricity price,CMEN(National energy research institute)think,When the market will far ultra planning.
