How Do Small Wind Turbines Work?
Wind turbines harness the natural kinetic energy that the Earth’s wind provides and convert it into clean electric energy for our homes. As the rotor blades are spun around by the wind, they drive a generator which harnesses the power.
The wind turbine will create energy whenever the wind speed reaches the cut-in speed for the model. For example, a turbine rated with a cut-in speed of 7mph will only start producing electricity when the wind speed reaches this threshold.
The turbine will produce energy anytime the wind blows fast enough. The energy is stored in deep cycle batteries, consumed, or fed back into the grid.
Wind turbine generators can lower electricity bills by up to 90% if employed in the right circumstances. They’re not an ideal fit for most people though. You can find out if they’re right for you in the next section.
There are two kinds of small wind turbine system that are available. Each has their own merits. Let’s take a look at each of them.
- The grid tied system – this system is connected to the national electricity grid. This type of turbine system will help reduce your consumption of utility supplied electricity. If the wind turbine doesn’t deliver enough energy then the grid makes up the difference. If the wind turbine makes too much energy then the excess can be sold to the utility. These systems make sense if your energy supplied by the utility is expensive, and their requirements for connecting your turbine to the grid are not too expensive.
- The stand alone system – this is the off-grid version which interests those who want to become self sufficient and produce clean energy. This version is usually used in conjunction with a solar electric system. In this instance, the wind turbine charges battery packs which store the electricity.
The generator will produce DC electricity in each case. This must be converted to AC electricity before it can be used by appliances in the home, or put back into the grid. This is done using an inverter. Some wind turbines will come as complete kits and include the inverter, but most are sold separately.
What’s Inside a Wind-Electric System?
Let’s break down the wind turbine into its component pieces. This should give a better understanding of how it operates. Knowing some of this terminology will help a lot when choosing the best home wind turbine.
Generator – this is the part that creates the electricity in the system. The motion of the rotors turning spins the generator which changes the kinetic energy into electrical energy. The generator is connected to the center piece of the blades and sits directly behind them.
Brakes – the best wind turbine design will include both manual and automatic braking systems. Automatic brakes can be used in some models for when the battery bank is fully charged. The manual brakes are needed for maintenance or even emergencies.
Batteries – an off-grid system will need a bank of batteries to store the electricity. The turbine will produce electricity whenever it spins above the cut-in speed. So you can stockpile this energy in the batteries for when it is needed. Lead acid batteries (deep-cycle) are the most common kinds to use. They can be wired in series or parallel to make a battery bank.
Controller – the charge controller is basically a safety feature that looks after the battery bank. It monitors the amount of energy stored in the batteries and protects the batteries from overheating when they are fully charged. When the batteries are fully charged the controller diverts the energy to the dump (see next component). We recommend MPPT charge controllers. They are a bit more expensive than PWM controllers, but they are much more efficient.
Dump – when the battery pack is fully charged, the turbine may continue to turn. Without a dump, the energy has nowhere to go and the system will run unloaded. This means it might spin extremely fast and may break. The dump protects the unit when the batteries are fully charged by ensuring there is still enough resistance in the circuit.
Inverter – the electrical energy made by the generator needs to be converted from DC to AC before it can be used.
Should I Get a Small Wind Turbine for My Home?
There are many good reasons to get involved with renewable energy sources like wind. People usually get involved with wind energy for environmental reasons, but other reasons include cheaper energy and a desire to be more independent.
It’s important that people remain realistic with their expectations about wind energy though. Despite being around for a long, long time there are reasons why wind energy is not all that popular. For a start, it is completely dependent on the consistency of wind. If you live in a place where average wind speeds are not high, then installing a wind turbine would be completely impractical and a total waste of money. Actually, that means wind energy is not a feasible energy source for most of us. Take a look at the map below that gives the average wind speeds across the entire country at 80m. If you live in a green area then you should forget about it right now (unless you live higher up). You can get all this information from the NOAA website.
For a home wind turbine kit to run efficiently and supply you with a decent amount of energy, the location is really important. The stronger and more consistent the wind, then the more energy you will have.
Wind turbines are very sensitive to even the slightest changes in wind speed. The amount of wind energy that you can harvest can be calculated very easily if you know the wind speed. The energy harvested by the wind increases with the cube of the wind speed. The relationship can be represented like this:
Energy harvested = (Wind speed) 3
This means that a 10 mph wind will yield 8 times as much power than a 5 mph wind. In fact, a wind speed increase of just 1.3 mph will create double the amount of energy. Furthermore, by choosing a place for your wind turbine that has 10% more wind, you will yield 33% more energy.
This relationship isn’t an exact scientific one, as there other other variables that will affect the amount of energy harvested. But, it gives a great indication of the amount of power you might produce in a given area.
The map above gives a great indication of general areas that receive a good amount of wind, but the immediate surroundings are vitally important too. A wind turbine must be able to function unimpeded from trees, hills, buildings or anything else that might affect the wind. Good sites for wind turbines would be hilltops, plains, fields, and ocean fronts. Anything close to a forest, city, or valley would run the risk of not getting a strong enough wind.
The easiest way to know for sure if your local weather is ideal for a turbine would be to measure it yourself. A digital handheld wind meter can be purchased on Amazon. To really get meaningful results you would have to monitor the wind speed regularly over a long period of time. Otherwise, information might be available from local meteorological sites. This data wouldn’t be as accurate as collecting your own “on-site” data, but would give a good indication. They might even keep historical wind speed data which would be a really useful resource.
If after all your research, you find that you live in an area with above average wind speed then you can start thinking about wind turbines. They are a great solution to off-grid energy headaches. Generally speaking, they work well in combination with solar panels, but can make sense on their own if your electricity rate is currently very high. Hot, sunny days don’t tend to be very windy, while those cloudy, sunless days are often much more windy. Wind turbines produce most of their energy in the winter, while solar panels do most of their work in the summer. A combination of the two is a great energy providing relationship for the environmentally conscious.

Installation & Maintenance
Installation Guide – Some things to consider before you install a wind turbine.
- Make sure you know the installation site inside out. Besides keeping the wind turbine clear of any physical wind obstructions like trees and buildings, make sure you know about the prevailing wind directions. The wind turbine needs to be situated upwind of any obstructions. It should be at least 30 feet higher than any obstacle within 300 feet.
- Plan for maintenance checks. Your wind turbine should last for at least 20 years, but it will require maintenance checks over the course of its life. Make sure that it can be easily lowered or reached for maintenance.
- Consider the amount of wiring used. Quite a lot of electricity can be lost due to the resistance of wire. Try and plan the installation site to keep the length of wire between turbine and batteries to a minimum. If you have to use a large length of wire then try to invert DC (direct current) to AC (alternating current) as the losses will be less.
- How will the turbine be supported? – Most manufacturers don’t supply a pole to attach the wind turbine to. You will either have to buy one, make one, or attach it to a roof or other surface.
- Ensure the whole set-up matches. If you choose a 12V wind turbine then make sure you also choose a 12V inverter and controller to match it. Likewise, if you choose a 24V or 48V system make sure they are all the same voltage. The dump load must be exactly the same as the power rating of the turbine too. If you have 400W rated turbine, then the dump load must match it.
Before installing a grid-tied system you will of course have to get permission from your utility company.
An off-grid system will also require batteries to store the electricity. They use deep cycle batteries, which are typically lithium-ion or lead acid. Most small wind turbines will require 12V batteries. These can be combined to make battery banks. These offer more energy storage space.
Both styles will require an inverter to change the current from AC to DC before it can be used.
Wind turbines have many moving parts and have maintenance checks performed on them every 6 months. With proper maintenance and care, a wind turbine should last 20 years or even longer.
A general maintenance check should include:
- Check the blades and nose cone for any superficial damage.
- Damaged blades decrease efficiency and can be dangerous.
- Check the blades nose cone are balanced and secured tightly.
- Check the nuts and bolts.
- Clean any dirt or residue from the blades and cone.
- Check that the electrical connections are secure and corrosion free.
- Check the condition of the battery bank.
- Use a multimeter to test the batteries.
- Clean and inspect the connections.
Before You Buy: Checklist
- Perform a local wind survey. This is an essential step, and will show whether a turbine is a feasible prospect or not. You can do this yourself using a wind meter. You would need to measure the wind at the prospective installation site on a daily basis for a long period of time (+1 year) to get worthwhile data. The other option is to use public information collected by meteorological agencies.
- Estimate the energy output of a wind turbine. We mentioned a simple equation earlier that can give a rough idea of how much energy that can be produced. This equation is helpful at the early decision making stage, but if you are truly serious about getting a wind turbine then there is a more accurate way of estimating the performance of particular turbines. This equation will allow you to see if it is a viable proposition. The equation is:
AEO= 0.01328 D2 V3
AEO = The annual energy output of a turbine (kilowatt-hours/year)
D = The blade/rotor diameter in feet
V = Annual average wind speed, in miles per hour (mph)
- Know the cut-in speed of the wind turbine. The cut-in speed is the minimum wind speed that is needed for the turbine to start producing electricity. If the wind speed is below the cut-in speed then the turbine will not produce any energy. It’s no good getting a model with a 9mph cut-in speed if your average wind speed is 8 mph.
