Both passive and active solar systems require exposure to the sun for heating or generating electricity. A passive system may also benefit from good exposure to the night sky for cooling. The basic environmental and site factors which affect solar access include climate and microclimate; latitude; topography; trees and landscaping; and human activities and structures. In some areas solar rights protect investments in solar systems. In California, the Solar Shade Control Act was passed in 1979 to protect systems from shading by neighboring trees. In 1986 passive system protection was removed in the case of Sher v. Leiderman, 181 Cal. App. 3d 867, 883 (1986).
