Consumer Grid Technical challenge
• Charging capacity • SOC calculations • Round trip efficiency • The wind turbines did not produce any eletricity • PV works perfect
The perfect wind turbine for villages • 25-200 kW • “Normal design” • Tilt-up tower • Max. 800 kg. piece (helicopter sling). • Site for Wind class III (Design for high survival wind speed) Wind turbine test center in Sisimiut
Lesson learned Wind turbines for towns Nanortalik 2x800 kW
