There's something odd about where China is building solar power

While China’s deployment of solar panels is highly impressive, its actual generation from these assets is much less so. China is apparently deploying scarce solar assets irrationally, installing substantial numbers of solar panels in several renewables-poor provinces while largely ignoring sun-soaked regions. Even worse, more than half of China’s new solar installations are dedicated to “distributed” rooftop generation sites, which suffer from poor utilization factors compared with utility-scale solar from power plants.

While China’s solar deployment has been extremely wasteful from an economic or environmental perspective, the shape of Beijing’s solar build may be influenced in part by security considerations. While rooftop solar increases an electricity grid’s “attack surface” and potential exposure to cyberattacks, it also disperses generation and generally increases system resilience, especially if microgrids are employed. Beijing’s solar strategy has evidently prioritized deployment of rooftop solar for government buildings and in provinces that hold key naval bases. If tensions over Taiwan, for example, increase or even break into open conflict, mainland China’s distributed deployment of rooftop solar could reduce its overall vulnerability to cyberattacks or other disruptions, granting Beijing’s leadership greater flexibility.
