It is appropriate to foster the rational use of energy together with the adoption of renewable energies in
order to reduce the climate change and ensure a sustainable development.

Operating
principle: Generally speaking, CSP technology is based on solar radiation concentration to produce steam or hot air which could then be used on conventional electric plants. Solar energy capture, which has
a relatively low density, is one of the main challenges on the development of solar plants. For
concentration, most of the systems use mirrors due to their high
reflectivity
Concentrated Solar Power
Main components•
Concentrator:
Different optics elements as mirrors, concentrate the sun on a point or a line where the receiver is located.
•
Receiver:
The receiver collects the concentrated sun rays and transfers the energy to a heat transfer fluid.
•
Evaporator: At the evaporator the heat transfer fluid transfers heat the water that becomes steam
•
Turbine:
The steam moves the turbine producing electricity as a conventional cycle.

1717Solar Power for a Sustainable World
HybridizationThe most used technology is
ISCC= Integrated Solar Combined Cycle
Operating principle: The heat coming from the solar field is used as extra energy for steam production on the combine cycle. Thereby the fuel is partly substituted by the solar resource
ISCC= Combine cycle + Solar field
Storage
The
most
used
technology
Operating
principle: Two
molten
salt
tanks
are used
•
System is charged by taking hot HTF from the solar field and running it through the storage heat exchangers. Simultaneously, cold molten-salt is taken from the cold storage tank and run “counter-current” through the heat exchangers
•
When electricity is needed, the system simply operates in reverse to reheat the solar HTF, which generates steam to run the power plant.

Operating
principle: When certain materials, called semiconductors, are exposed to solar rays, electrons from the valence band could be excited to the conduction band. The physical structure of the semiconductor creates an electric field which sets the electrons path, thus generating
direct electric current.
Photovoltaic technology
Main components•Optics:
Different optic elements, such as mirrors, Fresnel
lens, etc., concentrate the solar radiation onto a point where the photovoltaic cell is located.
•Photovoltaic Cell:
is the element where the photovoltaic effect takes place, producing direct current.
•Inverter:
Transforms direct current coming from the cell into alternating current.
•Solar Tracker:
In order to enhance the system's efficiency, the solar tracker has the function to orientate the photovoltaic module towards the sun.

Parabolic
Trough
Operating principle: The parabolic troughs are used to track the sun and concentrate sunlight on to the thermally efficient receiver tubes placed in the trough focal line. In these tubes, a thermal transfer fluid is circulated, such as synthetic thermal oil. This oil is then pumped through a
series of heat exchangers to produce steam. The steam is converted to electrical energy in a conventional steam turbine generator.

Operating principle: A circular array of heliostats (2 axis tracking mirror) is used to concentrate sunlight to a central receiver mounted on the top of a tower. A heat transfer medium in this receiver absorbs the highly concentrated radiation and coverts it into thermal energy
to be used by a turbine.
Main components:HeliostatsTowerReceptor
Characteristics:High temperatures High yields
High temperature tower under development will lead to best efficiency and costs
Operating principle: A fluid located in the receptor is heated by the concentrated rays.
This energy is then used to produce electricity by the Stirling engine
Characteristics:High efficiencies but still lots of challenges to overcome
