(2) A structural design feature, including the following:
(A) Solar racking, solar mounting, and elevated solar support structures, including, but not limited to, solar carports, solar shade structures, solar awnings, solar canopies, and solar patio covers, regardless of whether the feature is on the ground or on a building. Elevated solar support structures include the aboveground superstructure and associated foundation elements that support the solar collectors or other solar energy devices described in paragraph (1).
(B) Any design feature, whose primary purpose is to provide for the collection, storage, and distribution of solar energy for electricity generation, space heating or cooling, or for water heating.
(C) Any photovoltaic device or technology that is integrated into a building, including, but not limited to, photovoltaic windows, siding, and roofing shingles or tiles.
(b) Any instrument creating a solar easement shall include, at a minimum, all of the following:
(1) A description of the dimensions of the easement expressed in measurable terms, such as vertical or horizontal angles measured in degrees, or the hours of the day on specified dates during which direct sunlight to a specified surface of a solar collector, device, or structural design feature may not be obstructed, or a combination of these descriptions.
(2) The restrictions placed upon vegetation, structures, and other objects that would impair or obstruct the passage of sunlight through the easement.
(3) The terms or conditions, if any, under which the easement may be revised or terminated.
(c) As used in this section, “electric utility” means an electrical corporation as defined in Section 218 of the Public Utilities Code or a local publicly owned electric utility as defined in Section 224.3 of the Public Utilities Code.
