据CNBC网站3月10日消息 成本下降一直是太阳能推广的关键驱动力，但在2021年价格上涨，因为普遍经济挑战（包括供应链的限制）冲击着该行业。

根据太阳能产业协会和伍德麦肯兹周四发布的一份报告，去年太阳能产业的某些部分价格上涨了18%。

这是自2014年伍德麦肯兹开始跟踪数据以来，所有三个市场（住宅、商业和公用事业规模）的价格都出现上涨的第一年。

报告称，除了供应链瓶颈外，贸易行动和政策不确定性也对该行业构成了压力。

尽管如此，太阳能产业在2021年间新增了23.6吉瓦的新产能，比2020年的水平增加了19%。德克萨斯州全年新增太阳能最多，首次超过加利福尼亚州。

在住宅方面，安装量同比增长30%，创下50万台以上的新纪录。

Solar costs jumped in 2021, reversing years of falling prices

Declining costs have been a key driving force behind solar adoption, but in 2021 prices jumped as broad economic challenges — including supply chain constraints — hit the industry.

In some portions of the solar industry, prices rose as much as 18% last year, according to a report released Thursday by the Solar Energy Industries Association and Wood Mackenzie.

It was the first year that prices rose across all three markets — residential, commercial and utility scale — since 2014, when Wood Mackenzie began tracking the data.

In addition to supply chain bottlenecks, trade actions and policy uncertainty also weighed on the sector, the report said.

Still, the solar industry installed a record 23.6 gigawatts of new capacity in 2021, a 19% increase from 2020′s levels. Texas added the most solar during the year, overtaking California for the first time.

On the residential front, installations surged 30% year over year, hitting a new record above 500,000.
