Large Scale Solar Power System Design

Thin film solar cells use layers of semiconductor materials only a few micrometers thick. The receiver tube or heat collection element consists of a metal absorber surrounded by a glass envelope.

Subjects Architecture Nonfiction. The main components of tower technology include a heliostat, the receiver and the tower. Skip to the beginning of the images gallery. The absorber is coated with a selective coating to maximize energy collection and to minimize heat loss. Usually made of metal, the collector support structure holds the mirrors in accurate alignment while resisting the effects of the wind.

The promise of this market pressure and innovation holds great things to come in competitive renewable energy. The technology has been in use since the s. Photovoltaic technology uses a conducting material which performs this process, such as silicon. Find it at other libraries via WorldCat Limited preview.

Pacific Southwest Region via Wikimedia. Some of the technologies being developed and used include Fresnel point focus, Fresnel line focus and low concentration. We use this information to create a better experience for all users. The heliostats capture solar radiation and direct it to the receiver. In recent years the solar thermal market has experienced renewed growth and a number of technologies have emerged that include solar dishes, solar troughs, solar towers and linear fresnel reflectors.

Describe the connection issue. These cookies allow us to monitor OverDrive's performance and reliability. Mirrors can be made from thin glass, plastic films or polished metals.

The oil transports the heat from the solar field to the power block where the energy is converted to high-pressure steam in a series of heat exchangers. Also used is low concentration technology which uses mirrors instead of lenses to concentrate solar radiation. Since the solar radiation is much less condensed, conventional silicon semiconductors are often used because of their affordability.

Bibliographic information. Sunlight is reflected from parabolic-shaped mirrors and is concentrated onto the receiver tube at the focal point of the parabola. The most commonly-used reflective surfaces are glass mirrors. This presents a great opportunity for emerging economies to effectively meet their growing energy demands, especially since many of those countries possess an excellent solar resource.

The receiver sits atop the tower, and transfers received heat to an operating fluid e. This fluid is then transported to other parts of the plant to generate high temperature steam which then produces electricity through a turbine.

Physical description xvii, p. For example, they let us know which features and sections are most popular. Among the materials used in thin film are amorphous silicon and cadmium telluride.

The mechanical power is then used to run a generator or alternator to produce electricity. Mirrors focus the sunlight on an elevated absorber to heat and boil water, resulting in high-temperature steam that then drives a conventional turbine housed in a power block. Computer systems typically manage the mirror positions, tracking the motion of the sun throughout the day to maintain the focus point on the absorber. The sun tracking system is an electronic control system and associated mechanical drive system used to focus the reflector onto the sun.

Bibliography Includes bibliographical references and index. This heat is then used to generate electricity which can be stored or released directly onto the grid. Responsibility Peter Gevorkian. Find out more about OverDrive accounts. The fluid in these pipes is then pumped to make high-pressure steam, driving turbine generators and creating electricity.

Performance and reliability cookies These cookies allow us to monitor OverDrive's performance and reliability. At night and during stormy weather, the reflector units invert, exposing steel to the sky for reduced exposure to weather events such as ice, hail and high winds.

With an OverDrive account, you can save your favorite libraries for at-a-glance information about availability. This heat is transferred to a fluid, generating steam that in turn expands on a turbine that is coupled to a generator to produce electricity.

The main components of parabolic trough technology include the trough reflector, a receiver tube or heat collection element, and the sun tracking system and support structure. Industry experts predict that the trend will hold and perhaps even accelerate into the future as the demand for renewable energy resources escalates.

Trough technology is mature and clean, with a long track record demonstrating viability in large-scale application. Large Scale Solar Association. This authoritative guide fully addresses the complex technical and management issues associated with large-scale, grid-connected solar power system implementations. Since then, solar power at a utility-scale level has evolved in a number of exciting and revolutionary technologies. Solar concentrators boil water with focused sunlight, holy quran in english creating high-pressure steam that drives a conventional turbine to generate electricity on a utility-scale.

The heat causes the fluid to expand against a piston or turbine to produce mechanical power. Energy Systems Appendix C. Typically, the reflector is made of thick glass silver mirrors formed into the shape of a parabola. This energy is used to generate power by the engine or microturbine. The feasibility stage also includes site measurements, topography mapping, environmental setting assessment, and social impacts.

The dish-shaped surface collects and concentrates the sun's heat onto a receiver, which absorbs the heat and transfers it to fluid within the engine. Without these cookies, we won't know if you have any performance-related issues that we may be able to address. This technology has lower concentration ratios than Fresnel point lenses, so high efficiency silicon semiconductors are used instead of expensive GaAs semiconductors. More about Peter Gevorkian.
