Minnesota law provides for the creation of solar and wind easements for solar and wind-energy systems. As in many other states, these easements are voluntary contracts. However, unlike similar provisions in other states, Minnesota law specifically provides for wind easements in addition to solar easements. For tax purposes, an easement imposed on a property may decrease the property value, but an easement which benefits a property may not add value to that property.
Minnesota law also allows local zoning boards to restrict development for the purpose of protecting access to sunlight. In addition, zoning bodies may create variances in zoning rules in situations where practical difficulties, such as lack of access to sunlight for solar-energy devices, impinge on a particular property.
