谈沂鑫 东吴证券机械分析师: 各位领导晚上好，我是东吴机械的谭艺馨。今天和各位领导更新一下太空光伏深度，然后 再深度梳理一下各环节的一个推荐标的。最近整个太空光伏板块，它的催化还是非常多的 马斯克在这个达沃斯论坛上，明确了 SpaceX 和特斯拉会在 3 年内分别建设 100 吉瓦的 太空，还有地面的这个光伏产能。然后最近特斯拉和 SpaceX 的团队，也在国内的各大设 设备商进行了技术交流。然后订单，近期是有望加速落地的。然后在今，就在今天，马斯 克这边也是公布了 SpaceX 他会将收购这个 XAI 的这个 AI 公司。 形成它这个太空和 AI 算力的一个联动。所以我们认为，在 6 月 SpaceX 上市前，其实市 场的这个催化会一直不断。然后我们也是持续看好太空光伏设备这个板块的标的这样一个 可持续性。下面我们就汇报下报告，然后最后在报告的后面，我们再跟各位领导深深度的 梳理一下。每一个环节的这个标的。对于光伏设备来说，其实你真正要放量，还是要看太 空算力。因为你平时的这些通信或者传感的卫星，你的用量对于光伏的用量是没有那么大 的。所以我们这个报告也是围绕着太空算率去展开。 太空数据中心其实也很好理解， ...
