Xu Chen has spent 15 years in the solar sector, including a stint at GCL, a major producer of polysilicon. In this episode, Chen explains why costs for solar projects are increasing (up 8.5% in the first quarter alone), how enforcement of the Uyghur Forced Labor Prevention Act and tariffs are impacting supply chains and prices, the increasing efficiency of solar panels, and why pairing solar with batteries could ease congestion challenges on the electric grid.
