With the development of industry and
agriculture, a great amount of energy such as coal, oil
and gas has been consumed in the world. Extensive
use of these fossil energies deteriorates a series of
problems like energy crisis, environmental pollution
and so on. Everybody knows that the fossil energy
reserves are finite, some day it will be exhausted.
It is possible that the world will face a
global energy crisis due to a decline in the
availability of cheap oil and recommendations to a
decreasing dependency on fossil fuel. This has led to
increasing interest in alternate power/fuel research
such as fuel cell technology, hydrogen fuel, biodiesel,
Karrick process, solar energy, geothermal energy,
tidal energy and wind. Today, solar energy and wind
energy have significantly alternated fossil fuel with
big ecological problems.
With the development of the science and
technology, power generation using solar energy and
wind power is gradually known by more and more
people. And it is widespread used in many developed
countries. The merits of the solar and wind power
generation are very obvious-infinite and nonpolluting.
The raw materials of the solar and wind
power generation derived from nature, and wind
power generation can work twenty-four hours a day,
solar power generation only works by daylight. In
addition, this kind of power generation has no
exhaust emission and there is no influence to the
nature. But it also has some shortcomings. Because
of the imperfect of the technology, equipment of the
solar and wind power generation is very expensive.
By far, it cannot be widely used.
In addition, solar and wind power
generation system affected by the changing of the
weather very much, so it has obvious defects in
reliability compared with fossil fuel, and it is difficult
to make it fit for practical use the lack of economical
efficiency .Because of these problems it needs to
increase the reliability of energy supply by
developing a system which interacts Solar and wind
energy. This kind of system is usually called windsolar
hybrid power generation system significantly
3. INTRODUCTION
It is possible that the world will face a global energy crisis
due to a decline in the availability of cheap oil and
recommendations to a decreasing dependency on fossil fuel.
This has led to increasing interest in alternate power/fuel
research such as fuel cell technology, hydrogen fuel, biodiesel,
solar energy, geothermal energy, tidal energy and wind. Today,
solar energy and wind energy have significantly alternated fossil
fuel with big ecological problems.

13. Why we use MPPT Charger Controller
•Consider solar panel Kyocera KC 130. It is rated at 7.39 𝐴𝑚𝑝𝑠 at 17.6
It’s power output is 130 Watts .
•Panel puts out 7.39 𝐴𝑚𝑝𝑠 & battery charges under 12V
• 7.39 𝐴𝑚𝑝𝑠 * 12V =88.8 Watts
• We lost over 41 Watts. But we paid for 130 Watts.
• To overcome this loss, we use MPPT Charger Controller.
14. Working of MPPT Charger Controller
•Controller compares voltages of PV panel & Battery
•Figure out best voltage to charge Battery
• Example: Controller takes 17.6 Volts at 7.4 𝐴𝑚𝑝𝑠 & gives output to
10.8 𝐴𝑚𝑝𝑠 at 12Volts .
10.8 𝐴𝑚𝑝𝑠 * 12Volts = 129.6 Watts
• Now we still have almost 130 Watts.
17. WORKING
Solar & Wind turbine produced DC power
Inverter convert DC to AC
Controller monitors the system
18. CHOICE OF COMPONENT
Choice of components For 1000 Watt Load
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 = 12000𝑊ℎ/8ℎ=1,500𝑊.
•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/150𝑊=10
This shows 10 of 150 Watt solar panel will be required for this design
19. Charging Controllers:
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 =𝑃/𝑣=1000/12=83𝐴𝑚𝑝𝑠.
Since the value 83.3 A Charging controllers is not readily
available in the market then 1000A charging controller will be
used.
20. Battery capacity:
Given that the total load P= 1000W and
Operational period = 12 Hours
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
21. 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.

are much away from the construction site of large power
generating stations such as hydro and nuclear can be provided
power.
Also to satisfied the increasing demand of electricity with clean
hybrid power station by solar –wind can be used.
