Ecological Systems undertakes the installation of small wind turbines. The company is a NABCEP certified installers of wind electric generating systems. According to Ecological Systems, horizontal-axis propeller system works efficiently than vertical-axis systems. A horizontal-axis wind powered electric generator consists of a generator, a rotor, a mainframe and a tail. The kinetic energy of the wind is captured by the rotor and is converted into rotary motion that drives the generator.
The rotor with three blades runs smoothly and also more efficiently. The blades are made from fiberglass or wood. Fiberglass and wood give flexibility and strength to the blades and they also do not interfere with television signals. The generator with permanent magnet alternators is designed for the wind turbine. The mainframe has slip-rings to connect to the electric generators and the wiring of the fixed tower. The tail protects the wind turbine from overspeed and it also helps to align the rotor into the wind path.
A wind turbine can perform efficiently if it is positioned where the wind can get to it. When a 250W wind turbine is installed on a tower with a height from 30 to 50 feet, a 10kW wind turbine can be installed on a tower with a height from 80 to 120 feet. According to Ecological Systems, wind turbines should not be mounted on small buildings where people live in. The wind turbines may cause vibration, and noise problems. The ham radio antenna guyed-lattice tower is the cost effective tower for mounting smaller wind turbines.
