Many military bases have expansive parking lots to accomodate their employees working in multi-level buildings. These lots represent huge pieces of real estate that serve only one purpose. They could also serve as huge solar panel fields that would provide energy to the buildings, other activities on the base, and provide power to the local grid. Additionally, the lots would provide sporadic shade to employees' vehicles during the hot summer months. For an example, Cal Expo (California State Fairgrounds), Sacramento, CA has a solar field over their main parking lot.
