A leading VAWT manufacturer!
Our V3/V5 Competitive Strengths
Grand New Energy has designed its proprietary V3/V5 VAWT to effectively harness erratic wind in populated urban or suburban settings. The company has virtually eliminated vibration through customized operating software that also optimizes efficiency, reliability and life expectancy. Grand New Energy’s proprietary inverter and sensor board are engineered with safety and performance enhancing features such as monitoring of vibration, generator and ambient temperatures, over-speed protection, and optimization of aspect and tip speed ratios and power coefficient.
Our V3/V5 VAWT has been specifically designed, tested and certified to effectively capture wind off rooftops, ground-mounted monopoles or integrated into building designs;
Grand New Energy’s VAWTs are simple to install and need not to be raised high above a rooftop to operate effectively; they provide an excellent wind energy solution where there are height restrictions set by local regulations;
Our V3/V5 turbine, generator and inverter have been designed as an integrated system resulting in optimized system performance;
Its elegant design is simple and robust, resulting in long life expectancy and minimal maintenance;
Low nominal RPMs result in lower blade speed ratio and negligible audible noise or vibration;
Our unique sensor board has been integrated into the turbine for data collection and monitoring to control and protect the turbine;
The advanced emergency braking mechanism manages turbine speed and locks down the turbine when wind speeds are excessive;
Our turbine blades are made from gel-coated reinforced fibreglass, which minimizes icing conditions in the winter; and,
We offer offsite monitoring as an option via a web-enabled connection for preventative maintenance.
