Hybrid stand-alone photovoltaic power supply system DALI POWER TOWER

wind energy

Dali PowerTower is a hybrid wind-solar energy solution designed to maximise the efficiency of local power generation. It is installed on a design- and patent-protected 12 metre Dali XII wooden tower. The Dali PowerTower is suitable for a variety of applications. It can provide electricity for a summer cottage, a house, provide heating for hot water, power lights and electronic equipment - either connected to the grid or in remote locations, e.g., replacing a diesel generator (with a suitable battery backup). The Dali PowerTower Performance wind turbine has a permanent magnet generator with a great number of poles to reduce the rated speed to 250 rpm. This decreased rotation speed considerably reduces materials wear and noise. A low cut-in speed enables it to work with 3m/s wind speeds. Equipped with the passive centrifugal variable pitch system with shock absorber for power control and electric brake system. The blades are manufactured using RTM Light (Resin Transfer Moulding) technology based on the use of polyester resin with fibreglass. This results in lightweight components with greater mechanical resistance. Using this manufacturing process based on the most advanced technology used in utility scale wind turbines, the weight obtained is less than half of common blades, providing enhanced mechanical resistance.
