3. WHAT IS SOLAR ENERGY?
 The most precise Solar Energy definition : Energy from
the sun.
 But what is solar energy really?
There are two types of solar energy: Thermal
Energy & Electric Energy.
 Thermal Energy: Thermal Energy is everywhere. It heats
the earth, our bodies and our homes. It dries our clothes
. All for free!
 Electric Energy: Electric Energy uses the power of the
sun to produce electricity through solar cells, otherwise
known as Photovoltaics (PV).

4. • World Energy Conservation
predicted estimation about the
rate of utilization of energy
resources shows that the coal
deposits will deplete within the
next 200 to 300 years and
petroleum deposits will deplete in
next few decades.
• The most advantage using Solar
Energy is that this is distributed
over a wide geographical area,
ensuring that developing regions
such as India have access to
electricity generation at a stable
cost for the long-term future.

WHY SOLAR ENERGY?

5. MAIN USES OF SOLAR ENERGY
 The main uses of solar energy are:
1. In solar power plants
2. In water treatment
3. In water heating
4. In cooking

6. SOLAR POWER PLANT
 Solar power plant is based
on the conversion of
sunlight into electricity,
either directly using
photovoltaics (PV), or
indirectly using
concentrated solar power
(CSP).
 Concentrated solar power
systems use lenses or
mirrors and tracking
systems to focus a large
area of sunlight into a
small beam.
 Photovoltaics converts
light into electric current
using the photoelectric
effect.

7. TYPES OF SOLAR POWER PLANT
 There are mainly two types of solar power plants:
 1. Photovoltaic solar energy plant
 2. Concentrating power plant

8. PHOTOVOLTAIC POWER STATION
 A photovoltaic power station, also known as a solar
park, is a large-scale photovoltaic system (PV system)
designed for the supply of merchant power into the
electricity grid.
 Photovoltaic cells will capture the energy which is
generated from the sun and converted into electricity.
 They are sometimes also referred to as solar farms,
especially when sited in agricultural areas.

11. CONSTRUCTION AND WORKING
Solar array arrangements:
 The solar arrays are the subsystems which convert
incoming light into electrical energy.
 They comprise a multitude of solar modules, mounted
on support structures and interconnected to deliver a
power output to electronic power conditioning
subsystems.
 They are mainly of three type:
1. Fixed arrays
2. Dual axis trackers
3. Single axis trackers 11

12. CONSTRUCTION AND WORKING
Power conversion:
 Solar panels produce direct current (DC) electricity, so solar
parks need conversion equipment to convert this to
alternating current (AC), which is the form transmitted by the
electricity grid.
 This conversion is done by inverters.
Transformers:
 The system inverters typically provide power output at
voltages of the order of 480 VAC. Electricity grids operate at
much higher voltages of the order of tens or hundreds of
thousands of volts, so transformers are incorporated to
deliver the required output to the grid.

13. CONCENTRATED SOLAR PLANT
 The method of functioning of
these solar power plants is
similar to that of
the photovoltaic solar energy
plants.
 The extra addition in these
concentrating power plants is
that they make use of mirrors
and lenses in order to capture
energy from the rays of the sun.
 The light from the sun will be
directed towards the
photovoltaic cells and they will
be converted into heat energy.
13

14. CONCENTRATED SOLAR PLANT
 Concentrated solar power (also called concentrating
solar power, concentrated solar thermal, and CSP)
systems generate solar power by using mirrors or lenses
to concentrate a large area of sunlight, or solar thermal
energy, onto a small area.
 Electricity is generated when the concentrated light is
converted to heat, which drives a heat engine (usually a
steam turbine) connected to an electrical power
generator or powers a thermochemical reaction
(experimental as of 2013).

18. CONCENTRATED SOLAR PLANT
 Concentrated-solar technology systems use mirrors or
lenses with tracking systems to focus a large area of
sunlight onto a small area.
 The concentrated light is then used as a heat.
 Mirrors focus sunlight onto a glass receiver containing
water that can be heated.
 Water passes to heat exchanger for additional heating
using natural gas to make high pressure steam.
 Steam is fed to turbine which generates electricity.
 Electricity is transfer from storage substation.

19. TECHNIQUE USED TO CONCENTRATE
SOLAR ENERGY IN SOLAR PLANT
1. Parabolic trough:
 A parabolic trough consists of a
linear parabolic reflector that
concentrates light onto a
receiver positioned along the
reflector's focal line.
 The receiver is a tube positioned
directly above the middle of the
parabolic mirror and filled with a
working fluid.

20. TECHNIQUE USED TO CONCENTRATE
SOLAR ENERGY IN SOLAR PLANT
 2. Solar power tower:
A solar power tower uses an array of tracking reflectors
(heliostats) to concentrate light on a central receiver atop
a tower . These are more cost effective, offer higher
efficiency and better energy storage capability among CSP
technologies.

21. TECHNIQUE USED TO CONCENTRATE
SOLAR ENERGY IN SOLAR PLANT
3. Dish Stirling:
 The Stirling concentrating dish solar dish combines a
parabolic with a Stirling engine which normally drives an
electric generator.
 The advantages of Stirling solar over pv cells are higher
efficiency of converting sunlight into electricity & longer
lifetime.

23. CONCLUSION
 Solar energy is a resource that is not only sustainable for
energy consumption, it is indefinitely renewable. Solar
power can be used to generate electricity, it is also used
in relatively simple technology to heat water. The use of
skylights in construction can also greatly reduce energy
expenditure required to light rooms in homes interior
during day.
