Why In India
 India is in the sunny regions of the world with most parts of the
country receiving 4‐7 kwh (kilowatt ‐hour) of solar radiation per
square meter per day, 250‐300 sunny days in a year. Even though Solar
energy constitutes a miniscule part in India’s installed power
generation capacity (with grid connected solar PV generation at a mere 6
MW as of March 2010), in the medium and long run, it is expected that
solar energy, especially solar PV will form a vital component of the
country's energy mix.
Incentives from Government
• Jawaharlal Nehru National Solar Mission
initiated a Renewable Energy Certificate (REC) scheme
Excise Duty Exemption on Transmission Equipments
Subsidy in installation of Solar Power plant
Opportunities and Challenges
Land is a scarce resource in India and per capita land availability is low. Dedication of land area for
exclusive installation of solar arrays might have to compete with other necessities that require land. The
amount of land required for utility ‐scale solar power plants—currently
approximately 1 k m2 for
every 20 –60 megawatts (MW) generated could pose a strain on India's available land resource. The
architecture more suitable for most of India would be a highly ‐distributed set of individual rooftop
power generation systems, all connected
via a local grid. However, erecting such an infrastructure,
which does not enjoy the economies of scale possible in mass, utility ‐ scale, solar panel deployment,
needs the market price of solar technology deployment
to substantially decline, so that it attracts the
individual and average family size household consumer. That might be possible in the future, because PV
is projected to continue its current cost reductions for the next decades and be able to compete with
fossil fuel.
