DESCRIPTION
PRAMAC micro wind Turbines are suitable for many applications:

from residential houses to tourist resorts, from
streetlights to agricultural structures and everywhere
they effectively cut down energy costs and reduce
impact on the enviroment, combining efficency and
design.

This is a smart way to convert wind in energy into electricity and satisfy
everyday energy needs through an extremely efficient and, at the
same time, aesthetically appealing and noiseless tool.
PRAMAC WIND GENERATORS ARE VERTICAL AXIS
TURBINES (DARRIEUS H-SHAPE TYPE), SO:
  • Noiseless (unlike the Horizontal Axis Wind Turbines)
  • Very small in size
  • The function is independent from wind direction (unlike the HAWT)
  • This choice gives more freedom to Mr. Starck' design
