Reply to comment by Rokmonkey_ in In France all new large parking lots must now be covered in solar panels starting in july 2023. by BuildingBabel

Will those solar panels ever produce enough electricity to produce the steel needed to build the supports? If not they are carbon positive (not in a good way) from the start.

Steel is ~6000 kWh/ton to produce. My home solar array has so far produced 26000 kWh. I think they'll be fine.
