(Bloomberg) -- Chinese manufacturers that dominate nearly every step in the global solar power supply chain are being forced to slash prices as the coronavirus disrupts projects around the world.Costs for components like wafers and cells have fallen by as much as 20% since the start of the year. They likely haven’t bottomed out yet, either, as the outlook for demand remains uncertain and new mega-factories threatens to add supply.It’s bad news for the companies that make solar components and could lead to consolidation among some of the smaller players in the industry.
