2.  Solar power is energy from the sun
that is converted into thermal or
electrical energy. Solar technologie
s can harness this energy for a
variety of uses, including
generating electricity, providing
light or a comfortable interior
environment, and heating water
for domestic, commercial, or
industrial use

3.  Solar energy is defined
as the transformation of
energy that is present in
the sun and is one of
the renewable energies.

4. Types of Solar Energy
 Passive solar energy
 Active solar energy
 Solar thermal energy
 Concentrating solar power
 Photovoltaic solar power

5.  Passive solar design refers to the use of the sun's
energy for the heating and cooling of living spaces by
exposure to the sun. When sunlight strikes a building,
the building materials can reflect, transmit, or absorb
the solar radiation.
 Greenhouses and sunrooms are examples of
passive designs.

7. Concentrating solar power
 Concentrating solar power systems harness heat from
sunlight to provide electricity for large power stations. ...
The steam from the boiling water spins a large turbine,
which drives a generator to produce electricity
 Concentrating Solar Power (CSP) technologies use mirrors
to concentrate (focus) the sun's light energy and convert it
into heat to create steam to drive a turbine that generates
electrical power
 CSP technology utilizes focused sunlight.

8. Concentrating solar power

9.  Active solar systems are those which
collect solar radiation and convert it in the form of heat
to water, air, or some other fluid. ... A typical solar hot
water production system is composed of solar flat plate
collectors, a heat storage vessel and piping.
 Ex :- photovoltaic panels, collectors, voltage
controllers, blowers and pumps

10. Active solar energy

11. Photovoltaic solar power
 Solar cells, also called photovoltaic cells, convert sunlight
directly into electricity. Photovoltaics (often shortened
as PV) gets its name from the process of converting light
(photons) to electricity (voltage), which is called
the photovoltaic effect.
 Solar photovoltaic energy or PV solar energy directly
converts sunlight into electricity, using a technology based
on the photovoltaic effect. ... Photovoltaic, generators of
electricity to be supplied to homes. Thermal, installed on
houses to receive the sun directly.

12. Photovoltaic solar power

13. Solar thermal energy
 Solar thermal power/electric generation systems collect
and concentrate sunlight to produce the high
temperature heat needed to generate electricity. All solar
thermal power systems have solar energy collectors with
two main components: reflectors (mirrors) that capture
and focus sunlight onto a receiver
 Ex :- Solar thermal technologies of many types
include solar space heating, solar water heating,
CSP, solar air conditioning, solar crop drying, solar cooking,
and solar ponds.

15. Advantages & Disadvantages
Advantages Disadvantages
Pollution free & No green house effect Needs Lot of space
Reduced dependence on foreign oil
and fossil fuels
High initial cost
Virtually no maintenance as solar
panels last over 30 years
Expensive Battery
Safer than traditional electric current Uses a Lot of Space
Solar energy is a clean and renewable
energy source.
Solar Panels Could Damage Your Roof
Energy can be stored in battery Requires Sunny Weather To Work Best
Renewable source Manufacturing Of Solar Panels Can
Harm The Environment

16. Uses of Solar Energy
 Solar energy is a renewable, inexhaustible and
affordable form of energy.
 Environmental pollution can be reduced to some
extent.
 Solar energy for battery charging
 Solar energy for cooking
 Solar energy for houses
 Solar water heater

17. Conclusion :-
 In the coming years, technology improvements
will ensure that solar becomes even cheaper. It
could well be that by 2030, solar will have become
the most important source of energy for
electricity production in a large part of the world.
This will also have a positive impact on the
environment and climate change.
