Datong has advantages for developing the solar industry since it enjoys 2,800 hours of sunshine on average annually. Also,it has rich land resources including sunken land,the remains of coal mining. The solar panels in the sunken area are widely spaced with bushes planted in between to conserve water and soil and promote ecological protection.

In addition,its strong power grid(输电网)can transmit the electricity produced by solar power to Beijing,Tianjin and some cities in neighboring Hebei Province. Datong also has a science and technology park to promote scientific new ideas and appearance of industries such as high-end equipment manufacturing, e-commerce, culture, tourism and ecological agriculture.
