The purpose of this paper was to compile a nationwide survey by state, on legislation designed to protect access to solar energy. Brief summaries of the information received are included. Land use planning techniques and tools such as zoning and subdivision regulations, as well as special solar zones and planned unit developments have been discussed as they relate to protection of solar access and solar energy use. This paper has distinguished between two types of solar energy systems, active and passive, and associated problems with each.Primary concerns for the users of solar energy systems have been the availability of solar energy and its access to the collector's surface. Solar energy is environmentally safe, however, access to solar energy can be a limiting factor to its use. Solar access protection methods vary with location. The differences in needs between rural and urban areas have been discussed.Increasing solar technologies indicate the need for communities to regulate solar access through innovative legislation. This paper with brief introductions to solar energy access protection techniques, and the state-by-state survey was prepared so as to provide the reader with a basic understanding of solar access protection and act as a guide to access protection methods. / Department of Urban Planning
