what creations are pv kraftwerker know for
German companies, such as PV Kraftwerker, are developing mobile robots that can install ground-mounted solar panels day and night, in all sorts of weather. PV Kraftwerker's robot is designed to assemble power-plant-grade solar panels, which are four times the size of the ones you'd see on a home. Labor costs accounts for a growing fraction of the cost of solar power as panels get cheaper. According to PV Kraftwerker, a firm specializing in solar parks, installations that used to require 35 workers can now be done with just three workers in an eighth of the time. A 14-megawatt solar plant costs about $2 million to install the panels manually.
