Small wind turbines, referred to as "Little Fan", is rated at less than 100 kW wind turbines. Small fan can be off-grid applications, grid can also be applied. This article aims to explore the U.S. and the UK small wind turbine market situation, prospects, technology trends and certification in the hope for Chinese companies to enter the European market, small fan to provide reference.
The U.S. market for small wind turbines
According to the U.S. Wind Energy Association survey, the U.S. total of nearly 70 small fan manufacturers, accounting for the global small-fan 34% of the number of production enterprises. 21 enterprises in the United States in the production of the vertical axis small fan. At least 10 U.S. companies in the manufacture or plan to manufacture and installation of the small fan in the building. U.S. manufacturers in 2008 accounted for the global small fan Pin 49% of sales, exports accounted for U.S. manufacturers sold 28%. The United States in 2008, sales of small fans, 94% of the U.S. manufacturer. U.S. sales in 2008, 50-100kW in a quarter of the small fan is used to wind and diesel hybrid power generation, mainly for remote areas. U.S. small fan (capacity of 100kW or less) market in 2008, an increase of 78%. This increase was mainly due to private capital investment in manufacturing capability allows the United States greatly increased the industry predict a small fan next five years, the market will increase 30 times, the end of 2013 to reach 1,700 MW, of which most of the growth was helped by the U.S. Congress in 2008 Through eight years of the 30% federal investment tax credit.
UK market for small wind turbines
According to the British Wind Energy Association estimates that the United Kingdom in 2008, a small fan installed capacity of 7.24 megawatts, if the policy properly installed capacity by 2020 will reach 1,300 MW, in 2008 the UK electricity industry, a small fan to the 24.5GWh, obstacles can be overcome if growth by 2020, the UK electricity industry, a small fan to reach 1,700 GWh. By 2020 the number of British small fan installed more than 600,000 units.
The United Kingdom in 2008, the production of small fans, 50% exported to more than 100 countries, the main export model for the 0-20kW fan. By 2020, the United Kingdom small fan industry employment is expected to reach 5,800 people, market size more than 750 million pounds.
Small fan manufacturing trends Small fan manufacturing trends in the following areas:
Efficiency improvement L leaf: the efficiency of nearly 32% from 42-45% to
L alternator: the efficiency from 65-80% to 90-92%
L Inverter : Inverter efficiency gains not much room.
Design L continue to increase the swept area in order to capture more wind energy. This includes the use of new composite materials and molding process.
L to reduce system component count.
L Research and lightning, corrosion, Bearing Lubrication, generator insulation and electronic components associated reliability problems.
