 Chapter 110. SOLAR LAND USE

  § 110-4. Methods of collection.  

Latest version.

  • Solar collection systems come in a variety of configurations, utilize variable technologies and materials, and incorporate interrelated structures and components, in order to actively collect, convert, and transmit solar radiant energy in a safe and efficient manner. The terms and definitions provided in this section represent some, but not all, of the solar collection structures and components related to the solar land uses regulated by the provisions of this chapter.

    (1)

    Solar photovoltaic (PV) systems. A solar collection system which produces electricity by the use of photovoltaic cells which generate electricity when exposed to sunlight. A PV system may be roof-mounted or ground-mounted. Photovoltaic systems are generally comprised of the following components:

    (2)

    Solar thermal systems. A solar collection system which produces electricity by the use of photovoltaic cells which generate electricity when exposed to sunlight. A PV system may be roof-mounted or ground-mounted. Photovoltaic systems are generally composed of the following components:

    a.

    Flat plate collection. System which collects solar radiation to heat a liquid which, in turn, will be used to heat water or enclosed areas. This system generally contains a plate (panel) over tubes housed in a shell.

    b.

    Evacuated tube collection. System general composed of hollow tubes which contains a liquid used for the purpose of heating large volumes of water or heat water to a high temperature.

    (3)

    Concentrated solar systems. A solar collection system that uses mirrors or lenses to concentrate sunlight and create temperatures high enough to heat water or fluids to drive steam turbines that, in turn, create electricity:

    a.

    Parabolic trough. Curved mirrors are used to focus the sun's radiant energy onto a receiver tube that runs down the center of a trough. High temperature transfer fluid passes through a heat exchanger to heat water.

    b.

    Compact linear Fresnel reflector. Similar to the parabolic trough, with the exception of long parallel rows of mirrors being used as a lower-cost option.

    c.

    Power tower. Structure where mirrors are used to focus the radiant energy of the sun on a receiver at the top of a tower to heat transfer fluid to produce steam.
