(d)   Would it help if the wrongly-connected cell had an integral bypass
                                  diode?
                     5.5    (a)   Photovoltaics are renowned for their reliability. However, over the
                                  years, many lessons have been learned through failures in the field.
                                  List as many of these as possible, giving examples.
                            (b)   Discuss how similar problems have subsequently been avoided.
                     5.6    Explain what is meant in photovoltaics by the term nominal operating cell
                            temperature and why it is important for this parameter to be as low as
                            possible. Indicate how and why this parameter may vary with different
                            module designs.
