“Solar experts bet on efficiency improvements”
Increasing the efficiency is key to exploiting the cost reduction potential of solar PV facilities, say 58 percent of research and development experts from solar companies surveyed by the German Solar Industry Association (BSW). The improvement of quality and longevity (50 percent) and optimising the production process, as well as lowering the material cost through substitution or reduction (both 42 percent), were also mentioned. Costs have already been brought down by 90 percent in the past decade, according to a press release.
