據CNBC網站3月10日消息 成本下降一直是太陽能推廣的關鍵驅動力，但在2021年價格上漲，因為普遍經濟挑戰（包括供應鏈的限制）沖擊著該行業。

根據太陽能產業協會和伍德麥肯茲周四發布的一份報告，去年太陽能產業的某些部分價格上漲了18%。

這是自2014年伍德麥肯茲開始跟蹤數據以來，所有三個市場（住宅、商業和公用事業規模）的價格都出現上漲的第一年。

報告稱，除了供應鏈瓶頸外，貿易行動和政策不確定性也對該行業構成了壓力。

盡管如此，太陽能產業在2021年間新增了23.6吉瓦的新產能，比2020年的水平增加了19%。德克薩斯州全年新增太陽能最多，首次超過加利福尼亞州。

在住宅方面，安裝量同比增長30%，創下50萬臺以上的新紀錄。

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.
