Wind Turbine Buyer’s Guide
Maintaining a wind generator turbine is not a simple task. For a high performance turbine, expect to dig deeper
into your pockets.
Thus, the key is in design and installation because many variables that determine performance come into
When it comes to the purchase, it’s always good to first get the big picture. However, you have to start with
Most areas require a permit to purchase a wind turbine, so find out if your local regulations stipulate so.
Consider your electricity demands too; is solar power the most suitable make up for any deficit? Then the
location; what is the highest limit for mounting a wind
generator tower in your area? This is important because most domestic installations have lower limits,
given that the higher a turbine is placed, the faster the wind.
Ratings for wind turbines
It is a tricky affair when it comes to rating wind turbines. Whereas rated output for solar and hydro-electric
power systems is a realistic reflection of turbine capacity, the same can not be applied to wind turbines.
This is because turbine output is a factor of the average wind speed and different manufacturers rate output
using different wind speeds. In addition, wind power changes with cube of its wind speed, meaning that small
increments in wind speed cause large increases to rotor power.
For instance, a 10 percent spike in wind speed leads to 33 percent increase in available power. This translates
to a 1000 watt rated turbine at 28mph wind speed producing only 125 watts at 14 mph, half the rated
Selecting a wind turbine
To an ordinary buyer, this may be a little confusing, so the best thing to do is not to consider peak output and
the power curve. Instead, consider the turbine’s energy numbers for a year when estimating for the average wind
speed for your location.
When considering a turbine, energy should be your priority, not peak power. For instance, if you have a value
for the average wind speed of your location,
say 10mph, then you should select a turbine that can predictably generate energy in that speed range. Thus, a
turbine rated 300kwh per month should be able to generate that amount in wind speeds of 10mph.
If a manufacturer can not avail the energy estimates for the turbines, move to the next manufacturer. This is
basic information that they should posses. Basically, source for turbines with a reputable track record and
good warranty offer.
Although 5 years would be ideal, it’s a rarity in the not-so-big wind power industry. It is common knowledge
that a warranty reflects the manufacturer’s ability to stand by their product and the confidence they have in its
It’s also important to look at real world reviews from existing clients because they often carry more weight
than the manufacturer’s warranty. Ask a manufacturer for references or search for them from online resources.
Simply look for that particular model and you should be able to get the scoop on installation, performance,
durability and maintenance issues.
Proper preparation and adequate planning will save you many costs in the long run, which should be your ultimate
goal for acquiring a wind turbine system.
