You can go to Baoding to have a look. There are many companies there that are engaged in this field, and some are both. For example, Baoding Tianwei is a solar energy company. Baoding Huiteng makes wind turbine blades.
You can also go to Dongqi in Sichuan to learn wind power knowledge. Xiangdian Wind Energy in Hunan, Sinovel in Dalian, Zhejiang Huayi, Mingyang Wind Power, etc. are all wind power companies. Hope this helps you
