Fluctuating wind power generation due to wind, so the output is 13 ~ 25V AC change, subject to the charger rectifier, battery charger store again, so that electricity generated by small wind turbines into chemical energy. Then protect the inverter circuit, the battery inside the AC 220V chemical energy into electricity, can guarantee the stability of use.

Usually people think that wind generators solely by the decision, always wanted to buy a bigger wind turbine, which is not correct. The current to the battery charging wind turbines only, the energy stored by the battery up, people eventually use electric power, size and battery size more closely. Power depends on the size of even the size of wind, not just the size of the power head. On the mainland, a small wind turbine will be more appropriate than large. Because it is easier to drive and a small amount of wind power generator, continuous small wind, strong wind better than the moment a large supply of energy. When no wind it can also be caused by normal use of wind power, that is a 300W wind turbine can also be a large battery and inverter with the use, access to 500W or 1000W power out even more.

Use of wind generators, wind energy is pouring into our family used to the standard electricity, the savings level is obvious, a family only 20 yuan a year of electricity cost of battery fluid. Now the wind turbine performance than a few years ago a great improvement, previously used only in a few remote areas, wind generators connected directly to power a 15W light bulb, one out of a dark and often damage the bulb. Now, advances in technology, advanced chargers, inverters, wind power as certain scientific and technological content of the small systems, and can under certain conditions, instead of the normal electricity. Mountain to the system can not be a perennial money-lights; highway signs used it to do the night lights; mountain children can study up under fluorescent lights; urban high-rise rooftop wind turbine can also be used, which not only save but also real Green Power. Domestic wind generators, not only to prevent blackouts, but also increase the zest for life. In the tourism area, border, school, military and even behind the mountain, wind turbine generator procurement is becoming a hot one. Radio fans could use their own technology in wind power for the mountain people service, people watch TV and lighting synchronized with the city, but also make their own enrichment work.

The report, published on Thursday (click for PDF), found that sales of small wind turbines smaller than 100 kilowatts grew 78 percent last year, even though there was a sharp drop-off at the end of last year and beginning of this year.

The actual number of small turbines installed, though, is very small at over 10,000 units last year, comprising 17.3 megawatts of added capacity.

The stimulus act passed earlier this year gives people who buy a small wind turbine a 30 percent tax credit on the installation, which addresses the challenge of the upfront costs, which can be several thousand dollars to install.

Apart from policies, the other important factor to making a small wind turbine economical is siting. A study done that analyzed small wind installations in Massachusetts and one looking at roof-mounted turbines in the U.K.found that the machines underperformed manufacturers’ claims.

The best location for small wind turbines, most of which are mounted on poles, is an area with an average wind speed of about 12 miles per hour, said Ron Stimmel, the small wind advocate at AWEA.

“It all depends on your wind resource to get a decent payback,” he said. “You About Small Wind Turbine?Is Wind Right for Me need a little bit of land so you’re not talking cities, but mostly suburban and rural locations.”

Many municipalities have height small wind turbine is its use on monitoring sites limitations on structures but turbines generally perform well when they are 30 feet above any structures in a 500-foot radius, he said.

“If you find the wind annoying or have trouble keeping things on your porch, then you probably have enough,” Stimmel said.

Unlike large turbines, you don’t need to put up a tower to get data on wind speed but customers should look at wind maps and rely on installers to assess the resource, he added.

The dominant small wind turbine design is essentially a smaller version of the three-blade horizontal axis large turbines used in wind farms. But there are now hundreds of different small turbines, some of which are designed for homes or structures such as streetlamps.

Small wind turbine power generation cost per unit of electricity (KWH) of about 0.3-0.6 million, which can be seen this value than that of the Municipal electricity tariff is also low! Electricity than the island on a lot of low! Lower than the oil-generated electricity more!

For example: general fuel generators (medium) direct fuel cost of about 1.05 yuan / kWh, plus the loss of units, conversion efficiency, small load loss and so on, electricity costs at least 1.60-2.00 yuan / degree.

Small wind generator fuel cost of power generation units even higher, and with the resources to reduce the one day is bound to a variety of fuel prices rising day by day. This shows that the use of small wind turbines are the most practical, most economical and the most cost-effective and save money the best option.

The small wind turbine’s main technical features (refer to website www.allwindenergy.com )
