Products Description
Using the world's leading mechanical centrifugal variable pitch technology, the average annual power generation is 30% more.
(1) Large initial blade angle (+9 ), excellent acceleration performance, start at low wind speed of 2.5m/s;
(2) Below the rated wind speed, the wind turbine outputs efficiently;
(3) Above the rated wind speed, adjust the pitch angle so that the rotor speed is maintained near the rated speed and the power output is stable.
Project case
On-grid Systems in Other Countries
The systems were also installed in countries, like India, the Phillipines, Ireland, Colombia,France, Brazil, Swiss and Hungary.
