Netherlands-based startup Airturb has developed a 500W hybrid wind-solar power system that can be used in residential or off-grid applications. The system consists of a vertical axis wind turbine with a modified helical Savonius shape and a base with four monocrystalline photovoltaic panels. The roof load is 131 kg/m².
The solar base consists of a structure made of galvanized steel and rubber, measures 1.14m x 1.14m x 20mm and weighs 35kg. It can take on four solar panels, each with a power output of 30 watts. Each panel weighs 1.5kg and measures 1.5m x 0.7m x 1.5mm. The small wind turbine measures 1.8m x 1.14m x 1.14m and weighs 70kg.
The wind power system also includes a 300W axial flux PMS alternator (PMSA), which converts mechanical energy into three-phase alternating current. The hybrid system uses a dual-voltage hybrid inverter with an output of 500 W.
The complete package, including the solar mount and DuoVolt wind inverter, costs 4,235 euros ($4,626), excluding installation costs, according to the company's website. The system was designed, engineered and developed in the Netherlands, manufactured in Turkey and assembled in the Netherlands.
