In order to minimize environmental pollution, SolarWorld has adopted a material-
recovery process whereby obsolete, damaged, or old PV modules (including the
aluminium framing, tempered glass, and silicon wafers) are fully recycled and reused
to produce new PV solar modules. Figure 3.19 shows a robotic arm used in the lamina-
tion of solar panels. Figure 3.20 shows a monosilicon solar cell inspection station.
