That must explain why Walmart, (a publically traded company that is
LEGALLY REQUIRED to do what is in the best interest of shareholders
financial interests) is doing it all over the place. If it didn't have
a demonstrable ROI, they couldn't do it. They are responsible and
legally bound to the shareholders.

How do they turn a profit on the 100s of millions they give to
charities each year? I think they are earning good will with
their solar installs- not ROI.

In the long run that is a good thing because maybe, someday, solar
will be a viable option. But that time isn't here yet.
