This document discusses hybrid power generation using solar and wind energy. It begins by noting the potential for an energy crisis due to declining oil availability and increasing focus on renewable alternatives like solar, wind, fuel cells and biodiesel. Solar and wind energy are highlighted as significant alternatives that avoid fossil fuel problems and pollution. The document then provides details on the components, workings and optimal design of a solar-wind hybrid power system to provide off-grid or on-grid power. It explains considerations like panel and battery sizing to generate 1,000 Watts of power for 12 hours. Overall, the document promotes hybrid systems as a reliable, sustainable and clean approach to electricity generation without pollution.

3. INTRODUCTI
ON 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 ecologicalproblems.

11. COMPONENTS OF HYBRID
GENERATOR
Solar panel

12. Controller
Monitors the system starting and stopping engine as need

13. Why we use MPPT Charger
Controller
•Consider solar panel Kyocera KC 130. It is rated at 7.39 𝐴𝑚𝑝𝑠at 17.6
It’s power output is 130Watts .
•Panel puts out 7.39 𝐴𝑚𝑝𝑠&battery charges under 12V
• 7.39 𝐴𝑚𝑝𝑠*12V=88.8 Watts
• We lost over 41Watts. But we paid for 130Watts.
• To overcome this loss, we use MPPT Charger Controller.

14. Working of MPPT Charger
Controller
•Controller comparesvoltages 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 𝐴𝑚𝑝𝑠at 12Volts.
10.8 𝐴𝑚𝑝𝑠*12Volts = 129.6 Watts
• Now we still have almost130Watts.

15. Batteries

16. Inverter

18. CHOICE OF
COMPONENT
Choice of components For 1000 Watt Load
Solar Panel:
• Total load = 1000W
•Period of operation or duration= 12Hours
•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= 12V
P is the power supply rating= 1000W
Hence I =𝑃/𝑣=1000/12=83𝐴𝑚𝑝𝑠.
Since the value 83.3 ACharging controllers is not readily
available in the market then 1000Acharging controller will be
used.

20. Battery capacity:
Given that the total load P= 1000W and
Operational period = 12Hours
Watt-hour capacity = 12,000W-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 = 48,000W-hr
Now the choice of battery hour depends on A-H rating of the
storage battery.
For example 1500AH, 12Vbatteries the number of batteries that
will be needed is 48000/1500 = 32 batteries. Hence, for this
design , 1500AH 12Vbattery 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.
