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 play.

When it comes to the purchase, it’s always good to first get the big picture. However, you have to start with the basics.

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 speed.

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 features.

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.
