How many electricity power you can save per month with a 3KW wind turbine

To calculate how much electricity a 3KW vertical-axis wind turbine can save for your home each month, the following factors need to be considered:

1. Rated Power of the Wind Turbine

• Rated Power: 3KW, meaning it can generate 3 kilowatt-hours (kWh) of electricity per hour under optimal wind conditions.

2. Actual Power Generation

The actual power generation depends on factors such as wind speed and wind energy utilization. Typically, the capacity factor of a wind turbine ranges between 20% and 40%.

Calculation Formula:

Monthly Power Generation=Rated Power×Capacity Factor×Hours per MonthMonthly Power Generation=Rated Power×Capacity Factor×Hours per Month

Assuming a capacity factor of 30%, the calculation is:

Monthly Power Generation=3 KW×0.30×720 hours=648 kWh

3. Electricity Cost Savings

The electricity cost savings depend on the local electricity price. Assuming an electricity price of $0.2/kWh:

Cost Savings=648 kWh×$0.2/kWh=129.6 USD

4. Conclusion

With a capacity factor of 30%, a 3KW vertical-axis wind turbine can generate approximately 648 kWh of electricity per month, saving about 129.6 USD in electricity costs.

Notes

• Wind Speed: Variations in wind speed will affect power generation.

• Equipment Efficiency: Actual efficiency may be lower than the rated value.

• Maintenance Costs: Maintenance and installation costs should be considered.

Summary

• Monthly Power Generation: 648 kWh

• Electricity Cost Savings: 129.6 USD

These estimates are based on assumed conditions, and actual results may vary.
