Parking lots are one nice location to have solar panels.
You have vacant space that is not used for anything, your cars and other vehicles get better shade (if there was none earlier) and well, you generate some electricity as a bonus!
Thus, solar panels on industrial and commercial parking lots have seen significant adoption in the last couple of years.
Here is a nice blog post from Solar Mango providing details on this interesting topic of solar panels on parking lots. (part of Innovations in Solar series)
