3. INTRODUCTION
 ENVIRONMENTAL POLLUTION DUE TO THE CONVENTIONAL SOURCES OF
ENERGY AND ITS LIMITED QUANTITY HAS SHIFTED OUR FOCUS TOWARDS
NON-CONVENTIONAL SOURCES OF ENERGY, WHICH ARE IN PLENTY.
 DUE TO THE RISE IN PRICE OF FOSSIL FUEL, ITS EXHAUSTIVE NATURE AND
FACTORS CONCERNING ENERGY SECURITY, THE IMPORTANCE OF RENEWABLE
ENERGY RESOURCES IS INCREASING.
 THE MAIN MOTIVATION BEHIND THIS PRESENTATION IS THE COMBINATION
OF TWO RENEWABLE ENERGY SOURCES OF ENERGY, SO THAT GENERATION
COULD BE INCREASED, BE MORE EFFICIENT ALONG WITH BEING QUITE CHEAP.

4. SOLAR ENERGY
 ONLY ONE-FIFTH OF SUN’S ENERGY FALLS ON LAND
BUT IT IS STILL 2000 TIMES GREATER THAN TOTAL
WORLD ENERGY DEMAND.
 SOLAR ENERGY IS ENVIRONMENT FRIENDLY. WHEN IN
USE, IT DOES NOT RELEASE CO2 AND OTHER GASES
WHICH POLLUTE THE AIR. HENCE IT IS VERY SUITABLE
FOR INDIA, INDIA BEING ONE OF THE MOST POLLUTED
COUNTRIES OF THE WORLD.
 SOLAR POWER IS INEXHAUSTIBLE. IN AN ENERGY
DEFICIENT COUNTRY LIKE INDIA, WHERE POWER
GENERATION IS COSTLY, SOLAR ENERGY IS THE BEST
ALTERNATE MEANS OF POWER GENERATION.
 THREE MAIN TECHNOLOGIES DEVELOPED TO HARNESS
SOLAR ENERGY ARE PASSIVE SOLAR, SOLAR THERMAL
AND PHOTOVOLTAIC MODULES.

5. LIMITATIONS:
 SOLAR ENERGY IS NOT PREDICTABLE AND ALSO THE
POWER GENERATION DEPENDS ON THE AMOUNT OF
SUNLIGHT. THUS THERE IS NO GENERATION DURING
NIGHTS AND OVERCAST CONDITIONS
 THE EFFICIENCY IS ONLY 20% AND THE PAYBACK
PERIOD IS LARGE (AROUND 8-10 YEARS)

6. WIND ENERGY
 WIND ENERGY IS GENERATED DUE TO UNEVEN
HEATING OF THE EARTH’S SURFACE AND IT CAN
BE USED TO GENERATE ELECTRICITY USING
WIND TURBINE.
 WIND POWER PROJECTS CAN BE VERY
STIMULATING FOR LOCAL ECONOMIES.
 THE INSTALLED WIND POWER CAPACITY OF
INDIA IS 23444 MW AS OF 2014 . THE
EFFICIENCY OF THE SYSTEM IS AROUND 60%.
 WIND ENERGY IS ENVIRONMENT FRIENDLY AND
DOES NOT CAUSE GREEN HOUSE GASES.
6

7. LIMITATIONS:
 THE WIND IS IRREGULAR AND CONSISTENT WIND IS
NEEDED FOR CONTINUOUS POWER GENERATION.
 LARGE AREA IS REQUIRED FOR SETTING UP OF A
WIND GENERATION SYSTEM PLUS THE CAPITAL
COST IS ALSO QUITE HIGH.

8. THE HYBRID SYSTEM
 UTILITY CONNECTED WITH BATTERY BANK. THEREFORE BACKUP
IS PROVIDED IF THE UTILITY GRID GOES DOWN AND ALSO IF THE
WEATHER IS INSUFFICIENT FOR SOLAR AND WIND SYSTEMS
 THE COMBINATION OF THE TWO SYSTEMS NOT ONLY UTILISES
THE ADVANTAGES OF BOTH OF THEM, BUT ALSO REDUCES THE
LIMTATIONS OF EACH OF THEM
 THE DESIGN AND INSTALLATION MAY BE EXPENSIVE AND
COMPLEX, BUT THEY ARE EFFECTIVE IN PROVIDING CONTINUOUS
AND RELIABLE ELECTRICITY ALONG WITH REDUCED CARBON
EMISSION
 UPTO 72000 KWH OF ENERGY CAN BE SAVED USING THIS
SYSTEM.
 THE PAYBACK PERIOD IS ONLY ABOUT 5 YEARS.
 EASY TO OPERATE AND MAINTAIN,ECO-FRIENDLY,NO
POLLUTION AND NO RECURRING FUEL COSTS

9. THE HYBRID SYSTEM INCLUDES:
 PV-ARRAY: A NUMBER OF PV PANELS ARE
CONNECTED IN SERIES OR PARALLEL AND
IN PROPER ORIENTATION, GIVING A DC
OUTPUT OF INCIDENT RADIATION.
EFFICIENCY IS ONLY 14%
 WIND TURBINE: INSTALLED ON TOP OF A
TALL TOWER. COLLECTS KINETIC ENERGY
FROM THE WIND AND CONVERTS IT TO
ELECTRICITY COMPATIBLE TO THE
CONSUMERS’ ELECTRICAL SYSTEM.
 AERO-WIND GENERATOR: AN ELECTRIC
GENERATOR , WHICH IS DIRECTLY
CONNECTED TO THE PROPELLER SHAFT,
WHICH IN TURN ROTATES THE ROTOR OF
THE GENERATOR AND GIVES DC OUTPUT
9

10.  SOLAR AND WIND CONTROLLER:
CONTROLS BATTERY BANK CHARGE AND
DISCHARGE REASONABLY AND SAFELY.
 BATTERY BANK: SINGLE BATTERY OR
MULTIPLE BATTERIES CONNECTED
TOGETHER TO PROVIDE BACKUP IN
EMERGENCY CASES. AS WELL STORE
CHARGE DURING PEAK OUTPUT PERIOD
 INVERTER: A POWER CONVERTER THAT
INVERTS THE DC POWER FROM PANELS
INTO AC POWER.

11. APPLICATIONS
 REMOTE AND RURAL VILLAGE ELECTRIFICATION
 RESIDENTIAL COLONIES AND APARTMENTS’ GENERAL
LIGHTING
 STREET LIGHTING
 TRANSMISSION AND COMMUNICATION TOWER

12. CONCLUSION
 BECAUSE OF THE SOMEWHAT
COMPLEMENTARY NATURE OF THE SEASONAL
PROFILE, THE COMBINATION OF WIND AND
SOLAR IS BETTER THAN EACH INDIVIDUALLY
 HIGHER EFFICIENCY THAN INDIVIDUAL SYSTEMS
 UNDER THE CIRCUMSTANCE OF POWER
FAILURE THIS HYBRID SYSTEM KEEPS THE
CONTINUITY OF SUPPLY
12

13. FUTURE PROSPECTS
 THE GEOGRAPHICAL LOCATION OF INDIA IS IDEAL FOR TAPPING SOLAR
ENERGY EFFECTIVELY. THERE IS ALSO ENORMOUS POTENTIAL FOR
HARNESSING ELECTRICAL POWER FROM WIND.
 EFFICIENCY OF PV CELLS CAN BE INCREASED FOR BETTER HARNESSING
OF SOLAR ENERGY
 WIND POWER BEING INTERMITTENT, INTERCONNECTED GROUPS OF
WIND TURBINES OVER EXTENDED AREAS CAN BE USED TO ENSURE A
GUARANTEED MINIMUM POWER
 RESEARCH MAY BE UNDERTAKEN TO REDUCE THE INSTALLATION COST
OF THE HYBRID SYSTEM SUBSTANTIALLY.
