1. Wind Turbine:
- Choose a wind turbine with a rated power of around 5-6 kW to generate 8900 kWh per year in most areas with moderate wind speeds. Consider the average wind speed and turbulence intensity at your location.
2. Tower:
- Install the wind turbine on a sturdy tower of appropriate height. The tower should be high enough to capture sufficient wind energy.
3. Inverter:
- Use a grid-tied inverter to convert the alternating current (AC) generated by the wind turbine into usable AC power compatible with your electrical grid.
4. Electrical System Integration:
- Connect the inverter to your home's electrical panel, ensuring proper safety measures and compliance with local regulations.
5. Battery (Optional):
- If you want to store excess energy produced by the wind turbine, you can add a battery bank to your system. This will allow you to use the stored energy during periods of low wind or at night.
Example:
Let's say you select a 5 kW wind turbine that can generate an average of 2500 full-load hours (FLH) per year at your location. This means the turbine will generate 5 kW x 2500 FLH = 12,500 kWh per year.
Considering system inefficiencies and losses (such as inverter efficiency, cable losses, etc.), you can expect to generate approximately 85% of that amount, which is around 10,625 kWh per year.
By choosing a slightly larger turbine (5-6 kW) and optimizing your system efficiently, you can reach the target of generating 8900 kWh per year.
It's important to consult with a qualified installer and wind energy expert to assess the specific requirements and feasibility of installing a wind power system at your location. They can help you determine the most suitable turbine size and system configuration for your needs.
