回复: 刚拿到WAC号,随便写点经历,大家随便看看...
在光伏发电系统,多晶硅板所占成本在最高峰时约占总成本的25%左右。现在则更低了。所以谈不上是最大的支出。
当然,至于这部分怎么计算新的就业,我就不知道了。只是提供一个成本比例做参考。
大胸弟,这个不是光伏,是光热的。

BrightSource Energy’s proprietary LPT solar thermal energy system is engineered to produce predictable, reliable and cost-competitive clean energy when needed most.
BrightSource’s LPT
solar thermal energy systems generate power the same way as traditional power plants by creating
high temperature steam to turn a turbine. However, instead of using fossil fuels or nuclear power to create the steam, BrightSource uses the sun’s energy.
In the Unit 1 power block area, work on the steam turbine and air-cooled condenser (ACC) is progressing rapidly. The steam turbine and generator have been set on the foundation and assembly has commenced. The ACC allows Ivanpah to be “dry-cooled” versus wet-cooled, reducing water usage by more than 90% over competing solar thermal technologies using conventional wet cooling systems. The supporting structure of the ACC is under construction.
在沙漠中,太阳能热能产生高温蒸汽,推动传统的透平发电机产生电能。
传送距离较远,在沙漠中的电能传送成本也是巨大的。
