Today, the world is progressing at quite a fast rate with the use of the conventional sources of energy. The two major demerits of using them are the environmental pollution created by its use and its limited quantity. On the other hand the Non-conventional sources of energy are available in plenty, free of cost and pollution free. Many types of clean and renewable energy sources can be used in the production of electrical energy.

4. ABSTRACT
 The main scope of the project is to consume the power supply
from mains, generator, and inverter and solar most effectively.
 The outline of the project is selection of supply from mains,
generator, and inverter and solar automatically by using
microcontroller
 To give an uninterrupted power supply to the load

5. INTRODUCTION
 Today, the world is progressing at quite a fast rate
with the use of the conventional sources of energy.
The two major demerits of using them are the
environmental pollution created by its use and its
limited quantity.
 On the other hand the Non-conventional sources of
energy are available in plenty, free of cost and
pollution free.
 Many types of clean and renewable energy sources
can be used in the production of electrical energy.

6. INTRODUCTION
 These include solar energy, wind
energy, wave energy, hydroelectricity,
biomass energy, energy from wastes,
tidal power, and geothermal energy.
 All of these energy sources have
environmental benefits over the use of
fossil fuels.
 Our paper deals with the Energy
conservation Technique which is a
combination of two Non-conventional
sources of energy, i.e. Solar and Wind
Energy. 6

7. SOLAR ENERGY
 Four-fifths of the sun’s energy falls on the
oceans and drives the water cycle. Evapor-
ation from the sea causes rain to fall on the
land, resulting in the global hydropower
resource.
 The remaining fifth of the sun’s energy
falls on the land and is still about 2,000
times greater than total world energy
demand.
 The two main technologies that have been
developed to capture this energy are Solar
Thermal, and Photovoltaic modules. 7

8. WIND ENERGY
 The uneven heating of the earth’s surface by the
sun causes wind. This heat is absorbed by the
ground or water and is then transferred in to the
air.
 This causing differences in air temperature,
density and pressure. These differences then
create forces that push the air around. Like the
water that flows in the river.
 The wind contains energy that can be converted
in to electricity using wind turbines.
 Wind power projects can also be very
stimulating for local economics.

9. COMBINED SYSTEM
 Hybrid Systems -Utility Connected with Battery Backup. They are connected
to the utility grid in case the weather is insufficient for the solar or wind
system.
 But they also have batteries to store electricity in case the utility grid goes
down as well. The design and installation of these systems is more
complicated and expensive, but they are the most effective in providing
constant, reliable electricity.
 The System Include
1.PV Array 2.Wind Turbine
3.Generator Solar Controller 4.Wind Controller
5.Battery Bank 6.Inverter Loads

10. PROPOSED SYSTEM
Combining two energy resources such as solar and
wind energies
Storing of this resources
Stored energy can be used for different purpose

14. AERO-WIND GENERATOR
 This is one of the main components in
this system and converts kinetic energy
of wind in to electrical energy in the
wind in to mechanical energy.
 An electric generator is coupled to the
propeller shaft directly, this propeller in
turn rotates rotor of the electric
generator and in turn generates DC
electricity.
 The output from the wind generator
varies as per the wind speed.

APPLICATIONS

30. CONCLUSION
 Because the seasonal profiles of the wind and solar resources
are somewhat complementary in some reason, combination of
wind and solar perform better than either wind or solar alone
 Under the circumstance of power failure this hybrid system
keeps the continuity of supply without producing any noise
pollution, dislike any other power generating equipment i.e.
D.G. Set with noisy operation.
 High Efficiency than Individual systems.
 Since the longer pay back time of investing renewable energy
system, little firms are interested in investing the renewable
system.
