The paper giant installed 70.5 mega-watts last year and has announced an additional 129.5 mega-watts this week.
APP said it expects the installations to be one of the largest rooftop solar projects anywhere in the world.
The solar project will result in the installation of approximately four million square meters of solar panels, the equivalent of 560 football pitches.
The panels will be installed at APP operations at Gold East, Gold Hongye, Gold Huasheng, Hainan Jinhai, Yalong, Ningbo Zhonghua, Ningbo Asia and Guangxi Jingui mills in China.
“This project means APP will benefit from efficiency savings, while also making an important contribution to the local communities around our mills through the generation of clean and renewable power. It is a great example of how sustainability can have a positive effect on planet and people as well as profit. It also supports the Chinese Government’s commitment to increase the proportion of renewable energy in China to 20 per cent by 2030” said Bingjian Sun, Communications General Manager for APP-China.
All 200MW of capacity is expected to be installed within the next three to five years.
China is the world’s largest investor in renewable energy, investing more than $89.5bn in 2014 according to Bloomberg New Energy Finance.
