5 4 5 4 4 6 2 6 2 Defective Cell Analysis The fragile components of a solar cell combined with an extremely delicate manufacturing process periodically result in allunctioning solar cells that produce zero voltage. When included in a solar panel, these malfunctioning solar cells reduce the potential output of the cntirc pancl. In an effort to reduce the number of malfunctioning "zero voltage" solar cells that become part of their solar panels, SmartEnergy Solar Energy has begun sampling 5 panels (cach consisting of 32 cells) daily, looking for defective PV cells. 7 3 7 4 8 5 8 5 9 3 9 1 10 1 10 4 4 SmartEnergy has provided you with data from 15 days of "benchmark" production and they would like quality control chart(s) to be prepared with the control limits based on that dala. Furthermore, management would like to see recent sample dala from the last 15 days plotted against the control limits calculated from the "benchmark" production data. If the control charts reveal a reason to investigate, component shipments can be inspected and manufacturing production information can be obtained. Such an investigation should reveal the specific cause of why some PV cells are malfunctioning 11 6 11 2 12 5 12 6 13 3 13 3 14 7 14 1 Calculate the relevant control limits and prepare relevant quality control charlis) using 7-3 (show all work for full marks).
