Wind Generator Tower Basics
Wind generated electricity contributes 2.5 percent of the total power used worldwide. During the past 5 years,
new wind power installations have averaged around 27.6 percent.
Some countries have already achieved high penetration levels, mainly through large scale wind farms. Clearly,
there’s an upward trend for wind power usage, and predictions have shown that it can only get better.
Wind system components
A typical wind electric system consists of the following components: wind generator, tower and kits, inverters,
earth anchors, charge controllers, power controllers and storage batteries. The batteries and controllers are
optional, depending of type of installation. A wind tower forms one of the three basic components of a wind turbine
Wind tower installation basics
When considering investing in homemade wind
power, its important that you learn about the different tower installation options. Basically, for home
installations, you can either buy a ready built tower, which will set you back as much as the wind generator, you
can build one, or use one that comes in incline (tilt-up) and free standing design.
The wind tower alone could make up almost half the total costs for the whole wind power system. There are three
main types of wind towers used at a home setup level: lattice towers, tubular steel towers and fixed, guyed
Fixed, guyed towers are the least costly to install, if the set up for the guyed pole was correct. It is more
suited to the micro-turbine type generator, best for homes or smaller commercial class turbines.
Guyed towers are cheap but you have to contend with the multitude of cables running down to the ground
supporting the tower. It can be very inconvenient if there are residential properties around. The kits for these
towers usually contain no poles as they are locally available at even cheaper prices.
Lattice towers consist of angle wire metal pipes welded on three standing poles. They are strong and can reach
heights way higher than guyed towers. Their draw back is the costs for set up due to the sheer amount of materials,
shipping and construction.
Lattice towers are extremely strong as they allow wind to go through them, reducing the pressure exerted on the
tower. However, lattice towers are not a favorite for new, modern tower designs, and they are increasingly being
replaced by tubular towers.
Tubular steel towers are currently the most popular among new power installations worldwide. Although they are
far more expensive than lattice towers, they have a number of advantages over them too.
As such these towers are out of reach for majority of average home owners due to high costs. The towers are
strong, with a larger base and a smaller top. Larger towers are easier to maintain as they contain a ladder inside
for easy access to the generator without bringing the tower down.
The type of anchor required for a tower varies with location, thus, this is an important consideration too when
purchasing a wind generator tower.
Those are some of the tower basics to consider before deciding on an installation. However, there are many other
variables that come into play and may alter the original design. The best thing is to work with a professional wind
