INTRODUCTION
Most of the present energy demand is met by fossil and nuclear power plants .a small part is met by renewable energy technology such as the wind , solar , biomass , geothermal etc. there will soon be a time when we will face a sever fuel shortage. The wind and the solar power sources have experienced a remarkably rapid growth in last 10 years. Both are pollution free sources of abundant power. By adopting the appropriate technology for concerned geographical location you can extract a large amount of power from solar radiation. More over solar energy is expecting to be the most promising alternate source of energy. The global search and the rise in the cost of conventional fossil fuel are making supply demand of electricity product almost impossible especially in some remote areas. Wind energy is a kinetic energy associated with the movement of atmospheric air. It has been used for hundreds of years of sailing, grinding grains and for irrigation. Wind energy system converts this kinetic energy to more useful forms of power.

MAIN COMPONENT
PV ARRAYS :
A number of PV panels connected in series or in parallel giving a DC output out of the incident irradiance. Orientation and tilt of these panels are important design parameters, as well as shading from surrounding obstructions.

WIND TURBINE :
This is installed on top of a tall tower, collects kinetic energy from the wind and converts it to electricity that is compatible with a home’s electrical system. A wind turbine is a device that converts the wind’s kinetic energy into electrical energy. The blades of a wind turbine turn between 13 and 20 revolutions per minute , depending on their technology ,at a constant or

variable velocity, where the velocity of the rotor varies in relation to the

Velocity of the wind in order to reach a greater efficiency.
HYBRID CONTROLLER:
Control battery bank charge and discharge reasonable and safety.

Automatic management of the start/stop of the generation according to the voltage of the plant battery and the charging current.

BATTERY BANK:
Battery bank can be a single battery or multiple batteries connected together to create essentially one large battery of the required voltage and amp-hours capacity. In some ways the battery configuration and capacity are the most important electrical power decision to make, and a wise choice can help guarantee a steady supply of electrical power as well as a system that is simple to operate and maintain.

INVERTER:
A power converter that the DC power from the panels into power.

STEP UP TRANSFORMER:
Step up transformer are used at power stations to produce the very high voltages needed to transmit electricity through the National Grid power line.

LOAD:
Stands for the network connected application in the building that are fed from the inverter from the battery bank.

CHOICE OF COMPONENTS:
Choice of components For 1000 Watt Load
1. Solar Panel:
Total load = 1000W
Period of operation or duration = 12 Hours
Then, Total Watt-Hour = 1000×12= 12000W-hr
The period of the solar panel exposed to the sun = 8 Hours
(Averagely between 9am and 3pm)
Therefore solar panel wattage = 12000??/8?=1,500?.

Hence solar panel of 1,500W will be needed for this design.

If solar panel of 150W is to be use the number of panels to arrange in
parallel to achieve 1,500 Watt will be:
No of panel =1500W/150?=10
This shows 10 of 150 Watt solar panel will be required for this design
2. Charging controller:
For this design of 1000W solar power supply P=IV Where I is the expected charging current and V is the voltage of the battery and V= 12 V P is the power supply rating= 1000W Hence I =?/?=1000/12=83????. Since the value 83.3 A Charging controllers is not readily available in the market then 1000A charging controller will be used.

3. Battery capacity:
Given that the total load P= 1000W and Operational period = 12 Hour Watt-hour capacity = 12,000 W- Hr To make the chosen battery to last long it is assumed that only a quarter (¼) of the battery capacity will be made used of so that it will not be over discharged therefore hence the required batter capacity will be 12, 000 × 4 = 48,000 W-hr Now the choice of battery hour depends on A-H rating of the storage battery.

For example 1500AH, 12V batteries the number of batteries that will be needed is 48000/1500 = 32 batteries. Hence, for this design , 1500AH 12V battery should be used, Therefore the total number of storage battery required for 1000W solar power supply system = 32
4. Inverter:
Since the total load is 1000W it is advisable to size the required inverter to be 1500W as designed for solar panel ratings. Hence 1500W pure sign wave inverter is recommended in other to prolong the lifespan of the inverter.

Block diagram:

Generation though solar in India:

The country’s solar installed capacity reached 23 GW as of 13 June 2018 India expanded it’s solar generated capacity 8 times from 2650 MW on 26 May 2014 to over 20 GW as on 31 January 2018 .but the power generation by solar is less than wind power plant.

Generation through wind power plant in India:

World Wind generation capacity more than quadrupled between 2000 and 2006, doubling about every 3 year .the wind power production by India is 42.8 TWh . But the power generation by hybrid solar wind power plant is higher than wind power plant.

Generation through hybrid solar wind power plant in India:

The power generation from hybrid system is the highest in the year of 2014-15 where the power production is about 2743 MW from solar , 23444 MW from wind and 27184 MW from the hybrid system.

Application:
Hotels
Business (Institutions and Government)
Large Estate Houses
Factories and manufacturing facilities
Commercial Power generation
Street lighting
Advantages:
Very high reliability (combines wind power, and solar power)
Long term Sustainability
High energy output (since both are complimentary to each other)
Cost saving (only one time investment)
Low maintenance cost (there is nothing to replace)
Long term warranty
No pollution
Clean and pure energy
Provides un-interrupted power supply to the equipment

The system gives quality power out-put DC to charge directly the storage battery or provide AC.

The system can be designed for both off-grid and on grid applications.

Efficient and easy installation, longer life
Disadvantages:
Large number of harmonics is produced.

Initial investment is more.

Large space is required for larger generations
Wind energy systems are noisy in operation; a large unit can be heard many kilometers away.

Efficiency is less than conventional power plants.
