Three basic tower types are used for residential wind-electric systems.
Freestanding towers are the most expensive, but can be installed in very close quarters, and are perhaps the safest to install and maintain.
Tilt-up towers allow all maintenance and repair to be done on the ground, but require a large open area for installation and use.
Fixed-guyed towers include lattice and pole styles that do not tilt, and must be climbed for installation and service. These are typically the least costly, and need a moderate area for installation.
