The e220 design minimises start-up torque, which means energy is generated in low wind speeds. The passive pitch control system and power output at low wind speeds increases the energy harvest on an annualised basis, increasing returns to the owner. The standard finish of an etching marine primer, an intermediate protective coat and a polyurethane two pack finishing coat ensures protection from the elements. With a diameter of 2.2m the e220 is discreet in all installations and is suitable for urban environments
