2. INTRODUCTION
Hybrid systems, as the name implies, combine
two or more modes of electricity generation
together, usually using renewable technologies
such as solar photovoltaic(PV) and wind turbines .
Hybrid systems provide a high level of energy
security through the mix of generation methods.

9. METHODOLOGY
 Solar panel or photovoltaic (PV) cells has absorbed
sun beam by radiation and gives electric energy
output.
 Solar panels are the medium to convert solar power
into electrical power.
 A wind turbine obtains its power input by converting
the force of the wind into torque (turning force)
acting on the rotor blades.
 The amount of energy which the wind transfers to
the rotor depends on the density of the air, the rotor
area, and the wind speed.

10. METHODOLOGY
 Both system (Solar & Wind turbine) has produced
DC power.
 The both electric power has stored in the battery by
battery charger.
 Both power has controlled by inverter (DC/AC) and
supply to the lighting system.

17. Dynamo/Generator
Generator is an electrical device that converts
mechanical energy received from shaft into electrical
energy. It works on electromagnetic induction to
produce electrical voltage or electrical current.

19. Battery
The storage battery or secondary battery is such
battery where electrical energy can be stored as
chemical energy and this chemical energy is then
converted to electrical energy as when required.

20. Inverter
Inverter, is an electronic device or circuitry that changes
direct current(DC) to alternating current (AC). The
input voltage, output voltage and frequency, and
overall power handling depend on the design of the
specific device or circuitry.

21. LED Lighting Bulb
LED lighting is transforming the world in terms of their
ability to minimize energy consumption while producing
benefits that can last for years. Good LED bulbs can
provide light for decades while also taking a big bite out
of our electric bill every month.
