[2019-08-19]在中国，现在太阳能的电价比电网更便宜，五分之一的城市可再生能源的成本比煤炭低

内容:
Electricity produced from commercial and industrial solar energy systems is now cheaper in Chinese cities than that supplied by the national grid.
In addition, researchers found that when built into the local grid, solar generators produce lower-cost electricity than coal in 22 per cent of the country's cities.

在中国的城市，商业和工业太阳能系统所产生的电力现在比国家电网提供的电力更便宜。
此外，研究人员发现，在中国22%的城市，当太阳能发电机接入当地电网后，其发电成本低于煤炭。

The findings suggest that there may now be an economic incentive that will promote the uptake of commercial and industrial solar power systems in China.
China has become the global leader in the manufacturing of solar power systems — an enthusiasm that may spread from export to national use. 

研究结果表明，目前可能存在一种经济激励机制，促进中国商业和工业太阳能发电系统的普及。
中国已成为全球太阳能发电系统制造的领导者——这股热情可能会从出口蔓延到国家使用。

Chemical engineer Jinyue Yan of the KTH Royal Institute of Technology and colleagues estimated the total costs of setting up and running solar energy systems in Chinese cities and compared these costs with city-level grid electricity prices.
The researchers also estimated grid-scale solar electricity prices, comparing these with those derived from coal-fired power plants.

英国皇家理工学院的化学工程师严金岳(音译)和他的同事估算了中国城市建立和运行太阳能系统的总成本，并将这些成本与城市电网电价进行了比较。
研究人员还估算了电网规模的太阳能发电价格，并将其与燃煤发电厂的价格进行了比较。



'In recent years, China has become not just a large producer but a major market for solar photovoltaics,' the researchers wrote in their paper. 
'The solar photovoltaics industry in China [has] expanded from a tiny, rural-orientated solar programme in the 1990s to the global leader in what may soon be the world’s largest renewable energy source.'

研究人员在论文中写道，近年来，中国不仅成为一个大型太阳能光伏发电的生产国，而且还是一个主要的太阳能光伏发电市场。
他说，中国的太阳能光伏产业已经从90年代一个以农村为主导的小型太阳能项目，发展成为——可能很快就会成为最大的可再生能源领域的全球领导者。

Like many other developing countries, China has not substantially subsidised solar energy systems to counteract their initial higher costs.
Despite this, the availability of lower labour and system hardware costs may soon place parity with the nation's grid electrical prices within solar power's reach.
The full findings of the study were published in the journal Nature Energy.

和许多其他发展中国家一样，中国没有为太阳能系统提供大量补贴，以抵消它们刚开始较高的成本。
尽管如此，较低的劳动力和系统硬件成本，可能很快太阳能发电的价将与中国电网的电价平起平坐。
这项研究的全部结果发表在《自然能源》杂志上。

It is extremely unlikely that all costs have been taken into account. The amount of sunshine varies from Chengdu has just 1172 sunshine hours a year (3.2 hrs per day) to Ruoqiang that has 3101 hrs per year (8.5 hrs a day). So one needs to add itionally build back up battery storage for at least 4 to 7 days to cover the situation when there is no sunshine, and of courser, the solar farm cannot charge the batteries whilst it supplies electricity to homes and industry., unless you make the solar faarm bigger just for charging batteries.
Battery storage is far more expensive than solar panels. further solar panels have a life expectancy of 20 to 25 years (losing efficiency of about 10 years) and batteries a life expectancy of about 10 years, whereas a coal powered station will last for 60 to 80 years.
Studies like this never include all associated costs. - Up:66 Dwon:29

SanityCheck（西班牙）
把所有成本都考虑进去是极不现实的。日照时间从成都每年1172小时(每天3.2小时)到新疆若羌市每年3101小时(每天8.5小时)不等。因此，人们为了应对没有阳光的情况，理论上需要增加至少4到7天的电池储备，当然，太阳能发电厂不能在为家庭和工业供电的同时给电池充电。除非你只是为了给电池充电而把太阳能电池板做得更大。
电池的存储远比太阳能电池板贵。此外，太阳能电池板的预期寿命为20至25年(效率下降约10年)，电池的预期寿命约为10年，而燃煤发电站的预期寿命为60至80年。
像这样的研究，从来没有包括所有相关的成本。

Gas powered power stations (aka peaker plants) can be fired up quickly to provide power. They are already used to provide extra power even when there are coal-fired plants available, as the latter cannot ramp up and down as quickly. But just because the sun doesn't shine in one place, doesn't mean it is dark every where. Same for wind power. A large scale grid would solve many such issues. - Up:1 Dwon:0

天然气发电站(又称调峰电站)可以快速启动以提供电力。它们已经被用来提供额外的电力，即使有燃煤电厂可用，因为后者不可能像燃煤电厂那样快速上升和下降。但是，太阳不总是在一个地方，并不意味着所有地方都是阴天的。风能也是如此。大规模的电网将解决许多这样的问题。

In places with lots of sun and little coal, yes perhaps it is cheaper( but I still doubt it). It is far from being cheaper in places with lots of coal and little sun, like where I live.

在阳光充足、煤很少的地方，是的，也许会更便宜(但我还是有点怀疑)。在像我住的地方，有很多煤矿但很少阳光，太阳能远没有那么便宜。可再生能源永远无法为我所在的地区提供所需的能源，至少在很长一段时间内不会。他们可以在我的州的每一平方英寸安装一块太阳能电池板，但产生的太阳能却不能满足我们的需求。
