Protecting its forests and biodiversity is an important goal for China, which aims to increase national forest cover (20% in 2008) to 23% by 2020 and 26% by 2050. The 287,000-hectare Niuda forest farm, located in Shiping County within China’s Yunnan Province, is protected against forest fires and other threats by a monitoring network powered by an off-grid solar power system, built using advanced photovoltaic materials from DuPont.
挑战是为287,000公顷的森林农场提供雷达监测中心和多个子站的安全，可持续和成本效益。高海拔（海拔1,550多米）和地形难以安装电力接入或有线电视网络。由于不稳定的信号和该偏远地区的使用寿命高，移动电话也不是可行的选择。
