Rows of photovoltaic panels installed over the hills provide unique scenery in Nianzhang township of Xiaxian county in Yuncheng city, Shanxi province.

In recent years, the county has turned to constructing photovoltaic power stations on barren mountains as an important strategy for green and sustainable development.

They've made full use of local mountain solar energy resources and promoted the construction of photovoltaic and wind power projects, which have also contributed to rural vitalization and the incomes of local residents.

So far, the county's installed photovoltaic capacity reaches 10 megawatts and realizes an annual grid-connected power generation of more than 13 million degrees.
