Set and forget vs continually screwing with them/the corporate need for every time you purchase the building to inspect and replace. Lower tolerance of failure. If you have a lot of panels, losing 3 or 4 is acceptable.

I do ecological work and deal with solar farm projects pretty frequently. I like a lot of our solar farm designs because they allow for relatively undisturbed native herbs and grasses to thrive and basically block out areas for wild space as part of their footprint. I would much rather see installations that preserve wild space AND solar on roofs. Human settlements tend to be fluid in their purpose and built on top of, limiting long term viability of those panels. Throwing panels in a field for 25 years vs putting new ones on buildings every 5-10 years and throwing them away after.

That’s what orderlies are for
