Shi Zhenrong, Chinese solar industry pioneer, Founder of Sunman Energy
Examining the entire power system through the lens of photovoltaic (PV) products, the PV industry has experienced remarkable development in the past two decades. As a product, PV has achieved perfection in aspects like conversion efficiency, cost, capacity, and the supply chain. At 1 yuan per watt, costs in the PV industry have already reached a satisfactory low point. Further cost reduction would not only be unprofitable for the PV sector but might also fail to generate additional returns for the overall power system.
The PV industry can easily and swiftly achieve the goal of tripling installed capacity, or even more. The current bottleneck in industry development lies not in the production but in the overall power system. Today’s power system is not fully equipped to handle the intermittent and large-scale integration of PV and wind energy into the grid. Overcoming this challenge requires both top-level design and a rapid push toward the development of smart grid interconnection.
