Home Wind Power Practical Handbook

I. Project Assessment Phase

1. Wind Resource Assessment (Crucial First Step)

**On-site wind measurement is mandatory: Place an anemometer at the planned installation height and measure continuously for at least 3 months.**

**Focus on annual average wind speed:** Below 4.5 m/s, economic efficiency is very poor.

**Environmental Assessment:** Avoid areas shaded by buildings and trees; choose an open area.

2. Policy and Regulations Verification

**Check local planning restrictions and building height regulations.**

**Understand grid connection policies and subsidies.**

**Communicate with neighbors in advance to gain their understanding and support.**

II. Equipment Selection

1. Turbine Type Selection

**Horizontal Axis Turbine:** High efficiency but higher noise, suitable for open areas.

**Vertical Axis Turbine:** Low noise but lower efficiency, suitable for residential areas.

2. Key Parameters to Consider

**Start-up Wind Speed:** The lower the better.

**Rated Power:** Refer to the power generation capacity under ideal conditions.

**Survival Wind Speed:** Ensure it can withstand the maximum local wind force.

3. Tower Selection

Height Principle: The tower top should be 6-9 meters higher than surrounding obstacles.

Gentle Tower: Low cost but large footprint

Freestanding Tower: Small footprint but high cost

III. Installation Implementation

1. Foundation Construction (Crucial)

The concrete foundation must be poured according to design requirements.

Ensure the foundation's stability and durability. Pre-embedded parts must be positioned accurately.

2. Installation Precautions

Choose low wind speeds for hoisting. All connections must be securely tightened. Electrical wiring must be standardized, and proper lightning protection grounding is essential.

IV. System Configuration Recommendations

1. Energy Storage System

Configure a battery with sufficient capacity.

Select deep-cycle batteries suitable for frequent charging and discharging.

Add a controller to prevent overcharging and over-discharging.

2. Grid Connection Configuration

Requires a bidirectional meter and grid-connected inverter. Apply for a grid connection permit from the power company. Understand the electricity pricing policy for surplus electricity sold to the grid.

V. Daily Maintenance

1. Regular Inspection Items

Monthly check the tower and guy wire tightness. Quarterly check blades for damage. Annually check all electrical connections.

2. Common Troubleshooting

Decreased Power Generation: Check blade cleanliness

Abnormal Noises: Check fasteners and bearings

No Power Generation at All: Check controller and wiring

VI. Safety Precautions

Switch to safe mode immediately during thunderstorms

Disconnect all power during maintenance

Monitor equipment status during strong winds

Set up safety warning signs

VII. Economic Assessment

Calculate payback period: Equipment cost ÷ Annual power generation revenue

Consider maintenance costs and equipment lifespan

Compare local electricity prices and subsidy policies

VIII. Common Misconceptions

Insufficient tower height

Ignoring routine maintenance

Improper electrical installation

Overestimating power generation expectations

IX. Practical Suggestions

Start with a small-capacity system

Choose a brand with after-sales service

Keep complete installation records

Purchase appropriate insurance

Join user groups to exchange experiences

Summary: Home wind power is a long-term investment. The key to success lies in scientific assessment in the early stages, standardized installation, and continuous maintenance. Don't pursue maximum power; choose a system best suited to your home's conditions. Gradually achieve home energy self-sufficiency, provided it is economically feasible and technically reliable.
