You can't count all of those injuries against solar itself, though, as roofing injuries will happen regardless, and putting up solar panels greatly extends the life of a roof, so the amortized total injury to installers doesn't go up as much.

RE: Grandparent - the production of solar panels isn't as "green" as you may think. See: IEEE[3].
RE: Wind - The standard horizontal-axis blade design (i.e. what Siemens and other major commercial institutions offer) have ecological impacts on wildlife[4].

[0] Forgive the US centric analysis.
[1] I.e., cell-tower deaths are notorious for these sorts of violations -- both due to the endemic sub-sub-sub-contracting strategy that Verizon, et al, uses to distance themselves from the bad PR and litigation, as well as the employee these jobs tend to attract (risk takers/adrenaline junkies) who, even if given the proper gear will neglect to use it often due to machismo. Following full protocol, the injury risk decreases quite notably.

[3] http://spectrum.ieee.org/green-tech/solar/solar-energy-isnt-... Rare earth metals, processing with hydrofluoric acid, all the usual suspects one would expect. And this isn't a Koch-brothers funded gas/oil funded piece of propaganda. For goodness sakes, this is the IEEE -- about as pro-green (while keeping the science legitimate) as you can get.
[4] https://en.wikipedia.org/wiki/Environmental_impact_of_wind_p... - Just playing devils advocate here, offshore wind is basically the closest to a panacea IMO. There are events where 100% of the Dutch utility grid is powered entirely by their offshore wind. Their trains are 100% 'green' too (see: https://futurism.com/all-dutch-trains-now-run-on-100-wind-po...)
