The Zefr wind turbine is designed for the low wind regimes present in most urban and suburban environments. Depending on the annual average wind speed at your location, it could be configured as a three-, five or seven-blade module. The turbines can be mounted in a variety of ways (roof, parapet or wall) which makes them very adaptable to residential settings.
The company offers the ability to add a sail to each turbine which will increase their efficiency by 20%. You can also replace the sail with solar panels to build a hybrid system of wind and solar renewable energy.
