Wind Turbine Generator Power Ratings  

Article by Robert Easterling









Wind Turbine Generators are a fantastic means of generating your own power for a wide array of uses and despite their costs they still have a very good ROI in a reasonably short time period. We have been watching the technologies advance in their systems as well as a handful of those that the Chinese have been reverse engineering to steal from others. In both cases however it is absolutely critical that you get a second opinion BEFORE you jump into the purchase and installations.

A great many wind turbine generator manufactures use marketing ploys to make their systems appear to be capable of generating far more than what you or I could expect to see in powering our homes or businesses realistically. They make claims of power outputs that on the surface seem to be in line what we are looking for as a solution but in reality they have used wind speeds that are far above the average wind speeds in your particular part of the country to arrive at these power output claims. I really do not believe that telling someone they can get 10kw from a system on a consistent basis is very realistic when the actual wind speeds used to create that power are a steady 30mph.

Chinese manufactured systems that had their design origins in another country and from within private companies are really the systems you need to investigate fully before you spend a dime on them. Some nefarious types thinks its perfectly fine to reverse engineer a companies wind turbine generator to learn how to build exact copies and then sell on the open market at a much lower price, but be forewarned they did not build them using the exact same materials. You could expect to pay approximately ,000 less on one of these rip off copies but then that is not about to do you any good when the entire system fails a year or two down the road.

So how does one navigate through this global market place filled with the pitfalls of bad technology, crafty marketing strategies, or just plain old fashioned bad businesses trying to sell anything to make a buck? It is really quite simple! First make sure that you always get second or third opinions from reputable dealers who happen to also be NABCEP certified. NABCEP is the North American Board of Certified Electrical Practitioners and when it comes to all of the techno-babble that is floating around out there you need to look for a standard that has been established for your protections just as the NEC is the standard for all electrical contractors nationally.

Quality wind turbine generator systems are listed by your State Dept. of Energy and it is always a good idea to only work with companies who have partnered with the agencies in providing these types of systems and services. A good example would be what we have here in the state of Wisconsin which has an energy department known locally as Focus on Energy. This agency works directly with the Midwest Renewable Energy Association (MREA) and has established a great many programs which encompasses all of the renewable energy trades and personnel to including renewable energy market provider and service provider companies who sell, install and service renewable energy systems.

Customers wishing to learn more about making the move to renewable energy systems on their property are directed to working with them as all renewable energy incentive funds are issued dependent upon their site evaluations, systems specifications and designs, and of course completed installations. The end results of this cooperative working relationship are quality systems sold and installed at fair market values which can generate an acceptable amount or percentage of a given clients power needs. Those who chose not to work within this type of environment are typically those who were trying to save a buck or two and unfortunately found themselves stuck with systems that could not perform as advertised and without any recourse with the manufacture they purchased their systems from they lose far more than that dollar or two they were trying to save.

The moral of the story is that short cuts are NEVER a good idea when it comes to renewable energy systems and your best bet is to use ONLY NABCEP approved systems and personnel.

7 Most Frequently Asked Questions About Small Wind Energy Systems  

Article by yoni levy









7 Most Frequently Asked Questions About Small Wind Energy Systems1. How many turbines are needed to power a household or farm?

For a home or farm, one turbine is normally installed. The turbine’s size is chosen to meet the energy requirements given the available wind resource. Turbines with power ratings from 1 kW to 25 kW are typically used.

For village electrification applications, both single and multiple turbine installations are common, and turbines up to 100 kW in capacity may be used.

2. How much land is needed for a small wind system?

The actual space required for a small wind turbine tower is quite small. It can be as small as one square yard, but as a general rule, at least one-half acre is recommended for a single small turbine installation.

3. What size tower is used for a small-scale wind turbine?Usually a tower between 80 and 120 feet in height is supplied with the windturbine. Towers of this height raise the turbine above turbulence generated byobstacles (such as buildings and trees) on the ground. Also, wind velocity increases with greater altitude, so wind turbine performance improves with height.

How do small turbine costs compare to the costs of other alternatives?

Small wind turbines (ranging in size from 250 watts to 50 kW) are often the leastexpensive source of power for remote sites that are not connected to the utility system.

A study by the Congressional Office of Technology Assessment found wind to becheaper for meeting remote loads than diesel generators, photovoltaics, or utility transmission line extensions. (Micro-hydro also was found to be less expensive in many locations.)

Hybrid systems–wind/photovoltaic, wind/diesel, and other combinations–can often provide the most efficient and cost-effective option for rural electrification. Photovoltaics (PV)– the direct conversion of sunlight into electricity–is often used to supplement wind power since PV tends to operate best in low wind months. Diesel generators or batteries can be used for backup power and to maintain power production during low wind seasons.

One study of an Arctic community with annual average wind speeds of 15 mphcompared the cost of a 500-kW diesel system to that of a 200-kW diesel generator and four mid-sized wind turbines. If found that the wind/diesel combination cost considerably more to install (8,000 versus 5,000), but would deliver fuel savings of ,000 per year, paying for itself in less than three years.

4. Why are small wind turbines better than diesel generators or extension of utility lines in developing countries?

Small wind turbines are better because they are more sustainable and offer a number of other socioeconomic benefits. Wind systems come in smaller sizes than diesel generators and have a shorter construction lead time than extending the utility lines (“grid”). For grid extension distances as short as one kilometer, a wind system can be a lower cost alternative for small loads. While wind turbines cost more initially than diesels, they are often much better from the user’s point of view because of typical foreign aid practices.

Donor agencies, for example, typically supply diesels at no cost, but leave operational costs (fuel, maintenance and replacement) to be supplied by the local people. These expenses (in particular, fuel and parts) require scare hard currency. This usually leads to limited utilization and a shortened diesel lifetime due to inadequate maintenance.

Many countries must also import their fossil fuels, further magnifying the burden imposed by diesels.

5. How do small wind turbines compare with other renewable energy technologies suitable for decentralized rural electrification?

Wind power is very competitive with photovoltaics (solar), biomass, and dieselgenerators, but is usually more expensive than micro-hydro. Wind is also very attractive for the ease with which the technology can be transferred to developing countries.

Generally speaking, wind power complements these other power sources by providing a least cost approach under certain conditions. This expands the range of potential projects, pointing to the day when decentralized electrification projects will be implemented on the same scale as current utility line extension projects. In many situations, the lowest-cost centralized system will be a hybrid system that combines wind, photovoltaics and diesel.

6. Aren’t wind turbines too “high-tech” for rural people?

The high technology of a wind turbine is in just a few manufactured components such as the blades. A wind turbine can actually be much simpler than a diesel engine, and also require substantially less attention and maintenance. Some types of small turbines can operate for extended periods, five years or more, without any attention. With training and spare parts, local users can support the wind turbine equipment they use.

7. What companies make small wind electric systems?

The following AWEA members manufacture small wind electric systems:

*Atlantic Orient Corp.*Bergey Windpower Co.*Northern Power Systems*Southwest Wind Power Co.*Synergy Power Corp. (Hong Kong)*Wind Turbine Industries Corp.What companies make water pumping wind turbines?The following AWEA members manufacture water pumping wind turbines:*Bergey Windpower Co.*Southwest Wind Power Co.*Synergy Power Corp.

Windmills may be an environmentally friendly alternative energy source but they also cause debilitating health problems, say people who live near them. Wind turbines are popping up in rural communities around the world, including Canada, in the hope that they will reduce reliance on coal and other sources for power. Currently, there are about 1500 turbines across Canada and there are plans to build another 1000 to 1500 in the next year. But some residents who live near wind farms complain the turbines cause a number of adverse health effects, such as crippling headaches, nose bleeds and a constant ringing in the ears. Helen and Bill Fraser initially supported the nearby wind farm in Melancthon, Ont. One turbine sat close to the Fraser’s kitchen window. “We thought, more green energy, this is great,” Helen told CTV News.However, Helen says she developed headaches, body aches and she had trouble sleeping. The dog began wetting the floor at night. www.windaction.org

How to make a wind turbine generator  

Article by Mateusz Markowski









I used to ask this question whenever I received an electricity bill from the power station. But after a while I usually thought that I can’t afford to have my own wind turbine. I was sure it’s really expensive. A few weeks later I came across a very interesting DIY guide which in simple steps described the process of making a wind turbine. The author claimed that you can build your own wind turbine generator for less than 0, what seemed to be a scam. However, I trusted this guy and bought his e-book.

I was really surprised with the content of the guide. Everything was written very professionally but with no technical jargon, so you don’t have to be an engineer to understand it. What’s more the handbook included diagrams which were irreplaceable when assembling all the parts. I must say, it was a pleasure to me, although I had never done anything like this before. To be honest it reminded me of my childhood when I used to play with Lego. Yes, it was as simple as that!

But the best comes at the end of a month, when you get your electricity bill. I was completely suprised with what I saw, I managed to lower the bill by 60% in the first month using the wind turbine generator I built. Now, I can honestly tell you that I no more take energy from a power station, because I’m able to produce enough energy to satiate my family’s needs. Next amazing thing which you don’t realize at the beginning is that your wind turbine generator is a huge relief for the natural environment. You may not know this, but conventional sources of power severely harm the planet and give a significant contribution to the global warming.

Please, visit this site, it will help you choose the right DIY guide about building your wind turbine generator and cut down on your bills quickly!
