Rows of photovoltaic panels installed over the hills provide unique scenery in Shilou county, Shanxi province. They also contribute to local residents' incomes.

"So far, the county has constructed photovoltaic power stations with a combined installation capacity of 86.3 megawatts, which are aimed at eliminating poverty," said Hu Yuhai, deputy chief of the rural vitalization bureau of Shilou county.

"Stations with a capacity of 56.3 megawatts were built in villages across the country. These stations can generate a total annual revenue of more than 65 million yuan ($9.12 million) for villagers," Hu said.

"That's about 500,000 yuan for each village on average and more than 6,000 yuan for each household that was once registered as impoverished."
