Solar Resource Availability in India
 5000 trillion kWh solar radiation
incident in a year over India
 Radiation data collected by
India Meteorological
Department and some other
centres
 Daily solar radiation 4 - 7 kWh
per sq. m.
 Most parts of the country
receive solar radiation
sufficient enough to effectively
utilize solar energy systems
 Typically, 2.0 hectare of open
space is required for one mega
watt solar power plant

Issues of solar power
• Hugh land requirement
• Production of the solar cells carries an upfront
cost to the environment via production, but offers
clean energy throughout the lifespan of the solar
cell.
• Intermittent power generation & available in day
time only
• Low efficiency & CUF
• High capital cost & high Cost of electricity
generated
WIND ENERGY IN INDIA
• Installed Capacity of India 12009.48 MW as on 30.06.2010
• India ranked 5th in the World in terms of installed capacity
after USA, Germany, China, Spain.
• India has a potential of 48,199 MW

Hybrid RE Systems
In the future, several hybrid systems consisting of wind ,
solar, Biomass & small hydro installations could be
connected in clusters to form micro grids which can
support the functions of the smart grid by firming up
variable generation.
These micro grids can be integrated to a larger power
system or national grid. Some hybrid systems could be the
combination of the following:
PV/Battery, PV/Diesel, PV/Battery/Diesel,
Wind/Battery; Wind/Diesel; Wind/Small Hydro;
Wind/PV/Small Hydro; Wind/PV/Biomass.
Small Hydro/Biomass; Small Hydro/Battery/Biomass;
CONCLUSION
 Solar & Wind energy technologies are pollution free and
environment friendly and are compatible with smart grid.
 Hybrid systems shall help in firming up the variations in
generation .
 Wind energy has very good potential and it is the fastest
growing energy source
 The future looks bright for RE technologies as smart grid
technology will make these installations viable and
attractive for generators as well as consumers.
