看好光伏行业困境反转的投资者们，近期要被光伏股的持续大跌"砸"懵了。 自11月上旬起，光伏板块上市公司多次出现集体大跌。其中11月21日，超120只个股下跌，光伏板块指数跌幅高 达-5.75%。截至今日（12月3日），通达信光伏设备指数已跌至499.24点，相比11月11日的592.03点高点跌了15.7%。 12月3日，光伏板块再度整体萎靡，76只光伏股飘绿。截至收盘，光伏设备指数下跌1.17%。其中，国晟科技 (SH:603778)、双良节能(SH:600481)、爱旭股份(SH:600732)跌幅均超过3%；晶科能源(SH:688223)、晶澳科技 (SZ:002459)、天合光能(SH:688599)、中来股份(SZ:300393)等跌幅均超过2%。 这与年中以来光伏板块的集体上涨形成鲜明对比。原本在政策反内卷和硅料收储两大利好支撑下，光伏股走出了触底回 升的良好走势：到9月5日，已有多只光伏股较4月初翻倍；到10月9日，A股光伏设备板块年内实现上涨23.1%。然而， 大好形势已经不在了。 光伏产业链的情况也不乐观。硅料价格自9月下旬以来已连续9周未上涨，硅片和电池片则自10月中下旬以来连续下降， 以 ...
