WHY RENEWABLE ENERGY ??
Tremendous increase in energy demand.
Futuristic availability of Non-renewable
sources is a major concern.
Expansion of hydro, thermal and nuclear
power plants have serious environmental
issues.
Vital availability, Cheaper maintenance, less
pollution.
SUITABILITY OF RAJASTHAN
Located in the equatorial belt of earth.
62.11% desert area including Jodhpur, Jaisalmer, Bikaner, Nagaur, Barmer.
Equivalent energy potential is about 6,000 million GWh of energy per year.
Large areas of land are barren and sparsely populated.
TECHNIQUES
Solar power can be converted into Electrical
and Thermal energy in efficient manner.
Versatile used techniques
-Photovoltaic (PV): Electricity generation
-CSP system: Thermal power generation.
PHOTOVOLTAIC : ELECTRICITY
Based on Photoelectric effect .
Efficiency was limited few years back but
currently more than 40% efficiency is
yielding.
It is used in Rajasthan and Gujrat to produce
about 1150MW.
CSP SYSTEM: THERMAL POWER GENERATION
Lenses or mirrors and tracking systems used to concentrate solar radiation.
The concentrated heat is then used as a heat source for a conventional power plant.
Main Techniques:
- Parabolic trough
- Fresnel reflectors
-Dish engine system
-Solar power tower
JNNSM BIRTH SOLAR SECTOR
Before 2010 Rajasthan was compelled to
purchase power, power was generated
mainly through conventional sources.
After JNNSM Rajasthan got 46 projects
(285+150 MW).
Some other schemes are also implemented
like REC, Migration.

SOLAR POLICY 2011
It had a target to allocate 12 GW of solar power in the state by 2022. As a part of its first phase, the policy aimed to allocate 50 MW of rooftop Photovoltaic's (PV) of 1 MW each and 100 MW each of PV and Concentrated Solar Project(CSP) projects.
Productive use of abundant wastelands, thereby utilizing the non-industrialized desert area for creation of an industrial hub.
SOLAR POLICY 2011 (COND...)
Creating favourable conditions to solar
manufacturing capabilities by providing fiscal
incentives.
Generating large direct and indirect
employment opportunities in solar and allied
industries.
Create a solar centre of excellence.
CHALLENGES & SOLUTIONS
Solar Energy possesses tremendous potential in bridging India’s energy demand-supply gap in the future.
There are various challenges for this industry, including lowering cost of production, increasing R&D, consumer awareness and financing infrastructure.
Cost of solar electricity produced on-grid is Rs. 18.44/unit. This high cost is mainly due to dependence on imports for silicon and solar wafers used for the manufacture of solar cells – about 80% of which comes through imports.
.
C & S
It is important to overcome these challenges for fast growth and mass adoption of the technology.
Some of the immediate actions to enable growth are efficient implementation of REC, usage of carbon trading as a source of revenue, immediate implementation of grid powered energy, development of off-grid usage in various applications such as cellular towers and encouraging localized mini grids in areas that lack connectivity today
