OBJ: Develop and deploy new and renewable energy
for supplementing the energy requirements of the
country.
Ensure energy security, increase in the share of clean
power, energy availability and access, energy
affordability, and energy equity
About MNRE
• Introduction
• Utilization modes
• Refrigeration & Air Conditioning
CONTENTS
Introduction
• Soul of the modern world.
• Economics growth and technological.
• Three vital factors—economy, population and per capita
energy consumption.
• Green-house gas effect on the atmosphere’s ozone layer.
Solar Energy
• Time taken by light to come at surface of the Sun takes millions of years(this is
dependent upon mean free path considered) yet it reaches earth in about 8min.
• More energy in one second
than people have used since
the beginning of time.
• During nuclear fusion, the
sun’s extremely high pressure
& hot temperature cause
hydrogen atoms to come
apart and their nuclei to fuse
or combine.
Applications
• Photovoltaics
• Solar Thermal
• Solar Stills
• Solar Crop Dryers
ADVANTAGES AND DISADVANTAGES OF
SOLAR ENERGY
Renewable natural resource.
No carbon dioxide or other toxic emissions.
Solar thermal power to heat water or generate electricity
Not cost-effective in areas that have long periods of cloudy
weather or short daylight hours
The arrays of collecting devices for large systems cover
extensive land areas.
High voltage direct-current electricity
Various utilization modes
Factors
Ambient temperature
Latitute effect Wind speed Temperature recquirment
Direct normal radiation
Solar Energy
Clean efficient power that does not generate pollutants
• Reliability of continuous power without worry about brown/blackouts
• Easy installation since conduits and power lines are not required
• No monthly utility bills from your local power company
FLAT PLATE COLLECTORS
• Dark flat-plate
absorber
• Use both beam
and diffuse solar
radiation
• Do not require
tracking of the
sun
• Optical losses
• Thermal losses
EVACUTED TUBE COLLECTORS
• Thermo-
siphon
phenomenon
• Direct flow tubes.
• Heat pipe tubes.
