There is an intrinsic micro-mort rate for working on a roof. If you take this number and the number of hours that are spent working at height fitting solar panels (I got this from industry data a few years ago) its then fairly easy to put the annual deaths from fitting solar panels far above that of nuclear. These deaths are a ‘tragic accident’, rather than systemic so…

[edit: I can’t find a value for professionals anymore. This link mentions 1micromort per person on a ladder at home] [edit: clarity]
