VDMA: Module prices fell by more than 30 percent in 2018

Module prices fell by more than 30 percent in 2018. The average spot market prices »for a representative mix« of multicrystalline and monocrystalline modules in January 2018 and 2019 were $0.354 per watt and $0.244 per watt, respectively. The cost share of wafers fell from 19 to 14 percent and the cost share of cells rose to 26 percent. The share of module production rose to 46 percent of total costs in 2018, according to the new edition of the »International Technology Roadmap for Photovoltaic« (ITRPV) of the German VDMA Photovoltaic Production Equipment Association.
Accordingly, the »consistent implementation of PERC and other improvements as well as the use of improved materials led to higher average module outputs in 2018«. With improved and larger silicon wafers, improved cell fronts and backs, improved layouts, the introduction of bifacial cell concepts and improved module technologies, VDMA expects 60 cell PERC modules with an average output of 325 watts (multicrystalline), 345 watts (p-type monocrystalline) and 350 watts (n-type monocrystalline) by 2029. At this time, half cell PERC modules are expected to reach average module power classes of up to 400 watts (multicrystalline), 420 watts (p-type monocrystalline) and 430 watts (n-type monocrystalline), respectively.
The »International Technology Roadmap for Photovoltaic« is regularly updated by VDMA with technical contributions from industry and research. The aim is to reduce costs and increase efficiency by describing developments and trends in crystalline silicon-based photovoltaic technology. The roadmap is available at »itrpv.org«.
