Land Use
In Practice
For buyers of new construction in a jurisdiction with a solar mandate, the solar system is typically designed and installed as part of the building package rather than as a separate retrofit added after purchase. The mandate does not impose any obligation on purchasers of existing homes. In states and cities without a mandate, solar adoption is driven by voluntary economics supported by utility incentive programs, federal tax credits, and the cost of grid electricity.
