There are many aspects to Consider When Choosing a wind turbine. Here we will go in a little deeper at what makes the work effectively. We Will Also show how to calculate a wind turbine power and how it can moonrise go wrong.
How do I choose a wind turbine That suits me?
It Can Be Difficult But the first thing to look at is what you're after and how much of Their annual consumption you want to produce. And most want to have a piece That covers Their annual consumption, and it turns out When You count on the Merit That It provides a good return. However, One Should Keep in Mind That in this state can afford the little luxuries That Previously you had Because of the cost of electricity. Maybe you want to heat your garage with a heat exchanger or electric heater? You May Want to cool your Bedroom During the hottest days of summer? Or, you May have plans to install underfloor heating in the basement?The above parameters Affect the size of your work so you would be wise to think about your Estimated future consumption Because your investment will keep for 20 years.
Find a provider That you believe in.
It May seem strange That we Sunshinepro talk about how to find a good supplier. The reason for this Is that we'll get many calls about people who have acted turbines for big money the belief That They Should do themeselves and the Environment a favor, unfortunately, it turns out not always be so simple. There is no difference in this industry against other industries and there are plenty of adventurers and unscrupulous traders. Of course you can never be surethat the provider you choose is right and will be set up in all the years as a wind turbine to work, you May Try to avoid them less serious. We now have a good media for this and That Is The Internet search for "wind power failure" and other similar keywords to bring out what people write, search, of course, on the Intended traders / manufacturers name, you can always learn how Their customers react and how They believe That They have been treated. Of course, you will only find grievances and it is Because a satisfied customer does not make itself heard. Wind turbines are so complex That it would be strange if They did not go down sometimes but it's just When They go down as one Usually notice the difference between a serious supplier Responsible or rogues who do not want to know of the problems. It is a big investment so it is worth spending a few hours to find the right supplier.
How much power delivers a work?
This is a tricky question That is not easy to answer. The only completely reliable way to see what the work will generate is to set it up and measure! It is very Difficult to guess what effect your wind turbines will deliver. To make it even more Difficult, as all the wind power suppliers own opinion on how These values Should be used. One can, however, using a break party wind measurement and a constant wind / effect table from the manufacturer to make a pretty good assessment of what the work will deliver in a year, You should note count values Exceeding nominal wind as 100% given that there are few manufacturers who are able to deliver 100% in the winds over the nominal wind.There is an undeniable general rule That Applies to all wind turbines; • The larger the rotor, the better the effect in relation to the wind velocity. Example 1: If you compare two plants and one plant is 10kW, and the second is the 20kW and bothering have equal rotors AS These will deliver exactly the same amount of energy Until the wind comes up in the little plant's nominal power (eg, 10m / s). Thereafter 20kW to pass the Power When The Wind Increases Further. One can quite quickly Realize That the great work of These two will not be able to deliver twice as much energy as the small do, at least not in our climate.Thus, appearances can be deceiving. Just because the plant has a high peak power so it does not deliver more power. Example 2: We have two plants and These Are the same nominal power. One flat has a rotor on 6m and the other has to 8m. Now, if the manufacturer Claims That These will deliver as much as it is a very vague indeed. If now work with 8m rotor Reaches its peak power at 10m / s, so it comes with 6m rotor to reach its peak power at 12m / s, and then you can pretty quickly figure out That the work of 8m rotor is Significantly more efficient.
What is the average wind?
Suppliers thwart have lists Which sets out what the plant produces in different wind speeds. As a consumer, it is handy That You should compare them with the average wind you have where the work Should be friendlyness to get the annual production. This is true not so good with reality (can be a target, but not more). Here we will show why it is unreasonable. The scenario Is that you put up an anemometer at two different locations. One place has a fairly steady wind and in the second place, it is quite diverse with high winds and sometimes almost no winds in between. Both locations have an average wind speed of 7 m / s. Ex 1 365dagar in a year •182 Days of 4m / s (10 kW work Provides about 4000kwt on these days together) • 183 days with 10m / s (10 kW work Provides about 45000kwt on these days together) This gives an average of 7 m / s in one year in this case, a 10kW works to generate 49000kWt in a year. Ex 2 365dagar of one year • 182 days with 6m / s (10 kW Provides about 9500kwt one Those Days) • 183 days with 8m / s (10 kW Provides about 22500kwt one Those days) , this gives an average of 7 m / s in a year in this case, a 10kW works to generate 32000kWt in a year. As you can see the different 17000kWt on These examples, although Both locations have the same average annual wind. tryHappy to count themselves once you find a wind / kW table of any manufacturer. The tables Sunshinepro provides professional are calculated on a constant wind. So it is obviously not the reality, but it still gives a theoretical value. If you have a good wind measurement basis of 1year you can with this table produce a very good basis for future production. One Should keep in mind That the Winds are disturbed by the surroundings in the form of houses and forests can be so turbulent production That Could case by half in extreme cases. Do you think you will get 25000kWt from a machine That is probably closer to the truth 15000kWt, and do you think you will get out 18000kWt it is probably closer to the truth 8000kwt. Turbulens do more damage to production than what you might think.
What we have tried to say With These examples?
Well, what we want to say Is that all values and tables are to be Regarded As guidelines and You should not expect That These matches are fully in reality. This Should of course take into account when comparing different wind turbines and effects. You have to walk a bit on "gut instinct" and try to compare data sheet and dimensions. Now, if a manufacturer Claims That Their Work produces 30 000kWt and Their rotor is 6.5m and the other manufacturer Says That Their Work produces 20 000kWt with a rotor of 7.5m then it's pretty obvious That some of them are wrong! Of course, the efficiency of wings and resistance in the gearbox / drive play a role, but it is very small marginal differences in total.
