Solar power is the best sustainable energy source. The race to harness solar power with different tools and utilize maximum possible potential of solar energy is aggressively increasing.
2. Why Solar?
OLow depositions of Fossil Fuels
OClean And Eco-Friendly
ONo Carbon emission
OJawaharlal Nehru National Solar Mission
OCandidature of Paris summit
3. Types of Solar Power Plant
Type 1
To convert solar radiation directly into
electricity Photovoltaic (PV) cells are used.
Type 2
The heat energy of sun is used to rise the
temperatures of fluids and the kinetic
energy of these fluids is then used to drive
turbines.
4. PV based plants
O In PV based power plants Large area is submerged
under the solar panels which convert the radiations
into electricity directly.
O Upto 52% efficient.
O Household units are powered by PV.
5. Arising technology in PV
based plants
O PV based plants require mighty land area.
O Since land too, is a limited resource technology is
being developed for water head implementation of
these panels.
Canal-top solar uses the unused area above
canals to station the solar panels.
6. O The canal top structures prevent the evaporation of
water which is very beneficial for the irrigation
systems.
7. Floating Solar Technology
Panels are stationed over Water bodies like Lakes,
Ponds, Dams etc.
Efficiency is increased by upto 16% due to the back
cooling provided by water.
8. Utilizing heat energy in
radiations
O Concentrated Solar Power (CSP)
It optimizes the solar heat energy to
convert water into steam which is then
used to drive turbines.
It has again various mechanisms
designed like :
1. Linear concentrator
2. Power Tower
9. Parabolic troughs are linear
concentrators which implement the use
of curved reflectors to focus radiations
and heat the liquid.
10. Solar Power Tower
Most efficient CSP
plant.
Reflectors are tilted
according to the
movement of Sun.
Maximum Radiation
consumption.
Suitable for utilizing
and industrial
generation.
11. O The CSP in California is operational from
2014 with its 560MW capacity.
12. SWOT Analysis
Strengths
Clean and efficient as compared to other renewable
sources
Incentives provided by Govt.
Low Maintenance
Weakness
High installation cost and capital investment.
Installation area is a major concern.
13. Contd…
Opportunities
Wide scope for research
Elements like perovskite have future potential
Threats
Rising interest rates would further increase capital
investment.
A backup power plant is compulsarily needed to
provide at night.
14. Conclusion
O Solar energy is the most promising source
for satisfying the ever increasing power
need.
O The emission of CO can be reduced by
80% if the solar power plants are
implemented.
O Since solar power plants use the basic
physical phenomenon to convert energy it
has better life expectancy.
