在大力补贴的强推之下,大批光伏项目纷纷上马,关于光伏的研究和讨论也越来越多。但“弃光”问题很显然成为了补贴的后遗症,如甘肃、新疆,2015年全年弃光率已超过30%。以北京地区为例。2016年,光伏发电成本价格平均为0.8元/千瓦时,而北京居民用电在电压不满1千伏的情况下,收费价格分别为0.4883元/千瓦时(每月240千瓦时以内)、0.5383元/千瓦时(241-400千瓦时)和0.7883元/千瓦时(400千瓦时以上),工业用电虽然稍微贵点,但单价也是不超过光伏发电企业靠什么赚钱?
Under the strong subsidies, a large number of photovoltaic projects have been launched, more and more studies and discussions on photovoltaic. However, the issue of “discarding light” obviously became a sequelae of subsidies. For instance, in Gansu and Xinjiang, the annual rate of discard rate in 2015 exceeded 30%. Take Beijing as an Example. In 2016, the average cost price of photovoltaic power generation was 0.8 yuan / kWh, while that of Beijing residents was less than 1 kV at a voltage of 0.4883 yuan / kWh (240 kWh per month) and 0.5383 yuan / KWh (241-400 kWh) and 0.7883 yuan / kWh (400 kWh), although the industrial electricity is slightly more expensive, but the unit price is not more than what the PV power plant depends on to make money?
