Sos Roofline Systems

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

The wind power systems described in this text 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 necessities for a wind power system: 1. You own your own home.
2. Your property is at least one 0.5 acre.
3. Your householders association or town/county will not prohibit towers.
4. The average wind speed in your area exceeds nine mph.
5. Your utility permits web metering.

Wind Speed Needs

Most wind turbines have a start up speed of eight MPH however need a minimum average wind speed of twelve MPH to come up with an appreciable amount of electricity for your home. You can analysis the wind speeds in your area by consulting these wind maps: http://www.awstruewind.com/inner/windmaps/California.htm

Not surprisingly, the very best average wind speeds in California are registered within 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 forty-80 feet in height, your actual wind speed can be but what’s shown on the maps. As tower heights increase, the wind becomes faster and fewer turbulent. A twenty foot increase in tower height, from 60 to eighty feet, can increase the output of your wind turbine by as much as 36%.

Heap Size Requirements

A wind turbine needs at least [*fr1] an acre of land to ensure it can be located way enough faraway from wind impeding obstructions like trees, your house and other out-buildings. The tower should additionally extend 20 feet higher than 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 National doesn’t provide a wind power tax credit. But, California offers generous rebates for eligible wind turbines at the speed of $2.fifty a watt for the primary 7.5kW (seven,five hundred watts) of rated output and $1.50 per watt thereafter up to 50kW (fifty,000 watts). The complete list of eligible equipment is obtainable at:

As an example, Southwest Windpower’s Whisper 200, one,000 watt wind turbine would qualify for a $a pair of,500 rebate. This represents 50% of the full $five,000 value for a wind turbine, inverter and 80′ tower.

Wind Turbine Output

The Whisper two hundred turbine can manufacture 158kW per month at 12 MPH. The upper the common wind speed, the additional power it will generate. For many homes, 158kW represents only 20-twenty five% of monthly usage. On the other hand, your electric bill will immediately drop by 20-twenty five% and the value for electricity generated by the wind turbine twenty years from currently will be the same as it’s today.

At the opposite finish of the residential wind power spectrum is that the Bergey BWC 10,000 watt wind turbine. A 10Kw system is capable of providing all the required power for many homes. The initial cash outlay for a system of this size is around $forty,000 together with installation. This is before the $22,000 rebate from the State of California.

Wind System Towers

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

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

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

Blessings of Wind Power

The cost/profit of a wind power system makes them relatively cheap to own. With the rebate factored in, a 10Kw system will get hold of itself in as little as six or seven years. Mechanically, the straightforward style is easy to install and requires little if any maintenance. Although you will have your share of calm days, you will additionally have lots of windy California nights when you are wind turbine is spinning away whereas your neighbor’s solar array is literally collecting dust.
