The State of California leads the approach in renewable energy initiatives and offers generous rebates of fifty% for choose wind power systems.

The wind power systems described in this article are connected to the utility company, or grid tied, and don’t incorporate storage batteries. In California excess power generated by a wind power system will be sold back to the utilitiy (net metering).

The five basic requirements for a wind power system: 1. You own your own home.
2. Your property is a minimum of one 0.5 acre.
3. Your owners association or city/county will not prohibit towers.
4. The typical wind speed in your space exceeds 9 mph.
5. Your utility permits internet metering.

Wind Speed Needs

Most wind turbines have a begin up speed of eight MPH however require a minimum average wind speed of twelve MPH to get an appreciable amount of electricity for your home. You’ll research the wind speeds in your space by consulting these wind maps: http://www.awstruewind.com/inner/windmaps/California.htm

Not surprisingly, the highest average wind speeds in California are registered at intervals twenty five miles of the Pacific Coast.

The minimum height at which wind speed is measured on these wind maps is 30 meters, or a hundred feet. Since most residential wind turbine towers are 40-80 feet in height, your actual wind speed can be but what is shown on the maps. As tower heights increase, the wind becomes faster and fewer turbulent. A twenty foot increase in tower height, from sixty to eighty feet, will increase the output of your wind turbine by as a lot of as thirty six%.

Ton Size Requirements

A wind turbine desires a minimum of half an acre of land to confirm it can be located so much enough removed from wind impeding obstructions like trees, your house and other out-buildings. The tower must conjointly extend twenty feet above these obstructions. Typically speaking, the higher the tower, the a lot of land is needed by local zoning laws.

California Wind Power Tax Incentives and Rebates

Currently the Centralized doesn’t provide a wind power tax credit. But, California offers generous rebates for eligible wind turbines at the rate of $2.fifty a watt for the first 7.5kW (7,five hundred watts) of rated output and $1.fifty per watt thereafter up to 50kW (50,000 watts). The whole list of eligible equipment is accessible at:

As an example, Southwest Windpower’s Whisper two hundred, 1,000 watt wind turbine would qualify for a $two,500 rebate. This represents fifty% of the overall $5,000 price for a wind turbine, inverter and 80′ tower.

Wind Turbine Output

The Whisper 200 turbine can manufacture 158kW per month at twelve MPH. The higher the average wind speed, the a lot of power it will generate. For many homes, 158kW represents only 20-twenty five% of monthly usage. On the opposite hand, your electric bill can immediately drop by twenty-25% and the cost for electricity generated by the wind turbine twenty years from currently will be the same as it is today.

At the other finish of the residential wind power spectrum is that the Bergey BWC ten,000 watt wind turbine. A 10Kw system is capable of providing all the required power for most homes. The initial money outlay for a system of this size is around $forty,000 together with installation. This is often before the $twenty two,000 rebate from the State of California.

Wind System Towers

Three varieties of towers are most commonly used for residential wind turbines. The foremost expensive is the monopole tower. This can be a scaled down version of the towers used on wind farms.

The second type is the lean up tower. The tower is raised using an attached gin pole and is stabilized with guy-wires.

The third may be a lattice tower also stabilized with guy-wires. A abundant taller version of this tower is used by television stations.

Blessings of Wind Power

The price/profit of a wind power system makes them comparatively cheap to own. With the rebate factored in, a 10Kw system will purchase itself in as very little as six or 7 years. Mechanically, the simple style is simple to put in and needs very little if any maintenance. Although you’ll have your share of calm days, you’ll additionally have plenty of windy California nights when you’re wind turbine is spinning away while your neighbor’s solar array is literally collecting dust.
