A couple ideas for devices.
1. A shading device consisting of several umbrellas that work individually using a sensor but also communicating with other units in the system. Each unit would have to be very cheap and placed strategically w/o blocking views etc.

2. A contractable surface that can create shadow over a small or larger area. Like a branching robot that tries to spread out. Instead of fixed units with internal movement on the grid, they would move the grid, distorting and folding it, thus creating space. Maybe with a shadow boundary-finding algorithm?
