// Product Advantages
1. Permanent magnet direct drive technology drives efficient power generation
Using three-phase AC permanent magnet synchronous generator, eliminating the traditional gear transmission loss, power generation efficiency increased by 15%-20%, failure rate reduced. With large-diameter reinforced glass steel blades, 2m/s ultra-low starting wind speed can generate electricity, in the average annual wind speed 6-8m/s area, the annual electricity generation can reach 52,000 degrees, meet the annual electricity demand of 40 households, and the power generation efficiency is 30% higher than that of the same power segment models.
2. Intelligent control to achieve full scene self-adaptation
Support automatic wind + variable speed regulation, real-time optimization of wind energy capture efficiency. Built-in 12 safety protection mechanisms (overvoltage/undervoltage/lightning protection, etc.), automatic yaw unloading under extreme wind speed (≤50m/s), with -40 ℃~70℃ wide temperature design, stable operation in plateau, coastal salt spray and other harsh environment, annual failure downtime < 2 hours.
3. Modular design reduces operation and maintenance costs
Full maintenance-free structure: gearless design reduces mechanical maintenance points by 90%, the generator adopts aerospace grade sealed bearings, with a life of up to 20 years; The surface of the blade is coated with nano-corrosion resistant coating, and the weather resistance is increased by 3 times. The whole machine is modular assembly, and the tower installation time is 40% shorter than that of traditional models.
4. Deep adaptation of wind-wind complementary systems
The unique dual energy coupling technology can seamlessly dock solar panels to form a wind-solar complementary system, and achieve dynamic power balance through intelligent switching modules. When the light is insufficient, the wind power replenishment efficiency is increased by 30%, providing stable power for remote base stations, island electricity, agricultural irrigation and other scenarios, and the comprehensive power supply reliability of the system is 99.8%.
5. Low carbon environmental protection and cost-effective
A single unit annual emission reduction of about 32 tons of CO₂, equivalent planting 1700 fir, design life of 20 years. Compared with traditional fuel power generation, the 10-year operation period can save fuel cost 800,000 yuan, the investment payback period is shortened to 3.5 years, and the whole life cycle electricity cost is as low as 0.35 yuan, which is far more cost-effective than similar products.

// The following are common application scenarios of GWS-20KW horizontal axis wind turbines:
1. Remote areas and off-grid power supply：
In remote mountainous areas, islands and nomadic areas, traditional power supply methods are difficult to reach because they are far from the grid. The 20KW horizontal axis wind turbine is ideal for off-grid power supply. Taking remote villages as an example, due to geographical constraints, large power grid access costs are high. A wind turbine with energy storage equipment can stably supply power to about 30 households, meet the daily electricity demand such as lighting and home appliance operation, and completely solve the electricity problem. This not only gets rid of the dependence on traditional fuel generators, but also significantly reduces the cost of power generation, achieving a win-win situation for economy and environmental protection.
2. Agricultural irrigation and farm electricity:
In agricultural production, large-scale farmland irrigation requires continuous and stable power supply. The 20KW wind generator can directly drive the irrigation pump, which can meet the irrigation electricity demand of hundreds of acres of farmland when there is wind. For the farm, whether it is the ventilation and temperature control equipment of the livestock house, or the feed processing machinery, the wind turbine can provide sufficient electricity to ensure the breeding environment is suitable and improve the breeding efficiency. With a green and low-cost operation model, it injects new impetus into agricultural production.
3. Power supply for small industrial and commercial facilities:
Small industrial sites such as small processing plants, mines and construction sites, as well as commercial facilities such as gas stations, small tourist resorts and communication base stations in remote areas, have large power demand and high stability requirements. The 20KW horizontal axis wind turbine can be used as the main power supply or backup power supply to ensure that production and business activities are not affected by power outages. For example, small processing plants use it to drive production equipment and reduce electricity costs; Communication base stations rely on its power supply to ensure stable signal coverage, improve the quality of communication services, and effectively support the normal operation of various small industrial and commercial activities.
4. Wind-solar complementary distributed energy system：
The 20KW horizontal axis wind turbine is combined with solar panels to build a wind-solar complementary distributed energy system, which is widely used in urban fringe areas and ecological parks. During the day when the light is sufficient, the solar panel gives priority to power generation; At night or when the wind is strong on cloudy days, the wind generator will work by relay. This complementary model greatly improves energy utilization efficiency, provides clean and reliable power for residential communities and public facilities in the region, effectively promotes the development of distributed energy, helps achieve energy conservation and emission reduction goals, and promotes the wide application of green energy.
// FAQ
Q: What are the specific site requirements for installing wind turbines?
A: It is necessary to select an area with an annual average wind speed ≥4m/s, and there are no high obstacles within 3 times the tower height of the surrounding radius to ensure the effective capture of wind energy. The ground of the site should be solid, able to bear the concrete foundation, the foundation bearing capacity ≥80 tons.
Q: What is the power of this wind turbine at different wind speeds?
A: The starting wind speed is 2m/s, and power generation begins at this time, but the power is low. When the rated wind speed is 10m/s, the rated power can reach 20KW. When the wind speed is in the range of 3-10m /s, the generating power gradually increases with the increase of wind speed. When the wind speed exceeds 13m/s, the variable pitch system and intelligent control can keep the power stable and avoid equipment damage due to high wind speed.
