Dutch startup Airturb has developed a 500 W hybrid wind-solar power system featuring a vertical axis wind turbine and a solar base hosting four 30 W solar panels. The system can be used for rooftop or off-grid applications.
Netherlands-based startup Airturb has developed a 500 W hybrid wind-solar power system that can be used for 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 panels,” CEO Serkan Kilic said.”It has a roof load of 131 kg/m2.”
The solar base consists of a structure made of galvanized steel and rubber. It measures 1.14 m x 1.14 m x 20 mm and weighs 35 kg. It can host four solar panels with power outputs of 30 W each. It includes four Eco Line ES30M36 modules from Germany-based Enjoy Solar.
“The base can also host other types of solar panels,” said Kilic. The small wind turbine measures 1.8 m x 1.14 m x 1.14 m and weighs 70 kg. It has a ballast weight ranging from 70 kg to 100 kg and can operate with a temperature ranging from -25 C to 60 C. Every panel is made with glass fiber reinforced polyester, weighs 1.5 kg, and measures 1.5 m x 0.7 m x 1.5 mm.
The wind power system also includes a 300 W axial flux PMS alternator (PMSA) that converts the mechanical energy into electrical energy characterized as a three-phase alternating current. The hybrid system features a DualVolt Hybrid Inverter with an output of 500 W.
