2. INTRODUCTION
• Solar energy is most efficient , harmless and
renewable energy source
• Solar energy is very economical
• Solar energy is available everywhere
3. BACKDROPS OF SOLAR ENERGY
• Involves high initial costs
• Unavailability at all times
4. CSP
• CSP stands for Concentrated Solar Power
• Concentrated Solar Power (CSP) is a process of
concentrating heat in one point
5. HELIOSTAT
• A Heliostat (from Helios, the Greek word
for sun, and stat, as in stationary)
• Heliostat is a device that includes a
mirror, usually a plane mirror, which turns so as
to keep reflecting sunlight toward a
predetermined target
6. • Reflective surface of mirror is kept perpendicular
to the bisector of the angle between the
directions of the sun and target
11. WORKING
• The concentrated solar power used to heat fluid
deposit
• Working fluid is heated upto 250–1000°C
• This fluid is used to run steam turbine
12. TYPES OF SOLAR CONCENTRATERS
• Heliostats
• Parabolic trough collectors
• Stirling dish
• Fresnal concentrator
16. ADVANTAGES OF STP
• Capable of supplying power continuously
• High potential under the Renewable energy
sources
• Solar collectors absorb the energy from the sun 3-
4 times more efficiently than solar cells.
• The price of solar collectors is about 3 times less
than the price of solar cells.
• A solar collector also generates energy on cloudy
days
