国内12月装机大超预期，盈利承压扩产放缓。国内23年全年新增光伏装机216GW，同增147%，高基数下24年增速将放缓；内蒙古出台相关规定，利好新能源参与电力市场交易发展。需求端，组件招/中标规模同比改善，中标价格仍下降，2024年组件招/中标12.26/15.88GW，24年1月招标N型均价0.95元/W，P型0.88元/W，双玻占比84%，N型占比37%，N型渗透率提升趋势明确。供给端，PERC电池势微，开工率低迷，电池厂商陆续关停老旧产能，考虑到产能过剩&价格低位，部分N型扩产计划放缓。

招中标数据跟踪：1月招标数据环比提升，中标价格维持低位。2023年全年风电整机公开市场招标容量达61.17GW，同比减少39.18%；其中陆上风电整机招标容量达53.02GW，同比减少40.36%；海上风电整机招标容量达8.15GW，同比减少30.19%。2023年5.XMW、6.XMW机型为公开市场招标主力；2024年1月陆上风电裸机公开市场中标平均价格达1423 元/kw，同比下降20.84%，环比下降1.24%；海上风电含塔筒最新中标价达3096元/kw，创历史新低。

A commercial aircraft battery management system is a critical component in aviation that is responsible for managing and monitoring the health and performance of the batteries used in aircraft. These batteries serve various essential functions in commercial aircraft, such as providing backup power, emergency power for critical systems, and powering auxiliary equipment on the ground.

Consumer batteries are portable power sources comprising electrochemical cells, which can be recharged multiple times and discharged into a load. These batteries are produced in different shapes and sizes. They have applications majorly in consumer electronics, such as flashlights, smartphones, and foldable phones.
