A lot of solar development is compatible with other uses. This is the appeal of putting solar on farmland: It is common to be able to graze animals in the same area.<p>I would think of this like mineral rights. Mineral rights on land is distinct from other uses of the land and can be sold separately.<p>If there is a lot of money at stake, consider taking the contract to a lawyer specialized in land use laws. I would do everything in my power to lease them only exclusive rights to developing the solar potential of the land and keep the right to also do other things with the land that do not interfere with their solar power development.
