Some of our blades also feature a gull-wing-style tip. This helps increase stability and decrease the operating noise of the turbine.

Yes. In severe weather, high winds can create dangerous situations where turbines become unstable. With a residential turbine, the smaller size means less risk, but it can still be dangerous to let a small turbine spin out of control. A small wind turbine should be kept under a load or lowered to prevent items from striking the unit.

Here are the top-ranked hydraulic seal companies as of January, 2025: 1.Performance Sealing, Inc., 2.Hallite Seals International Limited, 3.HydraPak Seals, Inc..

Put simply: more blades are better for low winds, while fewer blades means more efficiency. For residential wind turbines, these differences are minor. Industrial wind turbines are almost always three blades to balance these concerns.

The simplest answer only asks further questions: it depends. Much of the information you’ll find online is focused on the benefits of the traditional three-blade turbine, but there’s a catch for residential wind power users.

We spend a lot of time crafting and optimizing the pitch of our turbines to sit in the sweet spot: just enough to perform in lower-wind condition.

Constructed from flexible materials like elastomers or plastics, hydraulic seals are essential in various machinery parts, including cylinders, valves, and pumps. They help maintain the necessary pressure differential within the system components, ensuring no internal fluid escapes. Common types of hydraulic seals include oil seals, O-rings, U-seals, and V-rings.

In contrast, a 7, 9, or 11 blade turbine may be better suited to areas where wind is harder to come by. Of course, they’re not magic—consult our guide to make sure your area has enough wind in the first place to make wind power a sensible choice.

A hydraulic seal is a critical component designed to contain fluids and prevent leaks in machinery and equipment, typically where oil is the working medium. It serves a dual purpose: it keeps fluids under high pressure contained within the system and prevents contamination by external particles. This dual functionality enhances machinery efficiency, ensures reliability, and reduces fluid waste.

We know that a few of the concerns that limit commercial turbines to three blades are not a concern for residential turbines.

This guide is meant to help you see the benefits of different materials, shapes, and configurations and help take you from overwhelmed to empowered.

Since the air coming off the blade is moving a bit faster than the air flowing into the blade, each blade is able to generate RPMs and power in its turn.

Fortunately, we have a good deal of experience using with residential wind turbines—farmers in the rural west have been using wind as their primary energy source for nearly a century.

Pretty much all residential wind turbines commercially available have a similar profile—for good reason. Following the same principle as aircraft (and bird) wings, the blade design is designed to sculpt the airflow over the blade.

There’s a lot of information out there when it comes industrial-scale wind turbines, but a lack of corresponding science for residential wind turbines.

The pitch of your turbine blades—the angle of the blade’s windward edge—is a key factor in maximizing your turbine’s efficiency, especially at low windspeeds.

A turbine blade’s pitch is the angle of said blade’s windward edge. The degree of pitch can affect the turbine’s performance by either not generating flow over the blade (too narrow) or creating too much drag (too wide).

If you live in an area that’s prone to severe storms and unpredictably high wind, it may make more sense for you to install a 3 or 5 blade turbine or simply shortening the tower height.

Aluminum or carbon-fiber? Three blades or eleven? And what difference does that zinc plating make? The possible configurations can feel a bit overwhelming.

The other major concern for large turbines is drag. Some drag can help keep the commercial turbine stable and safe, but too much drag harms the turbine’s overall efficiency.

Hallite Seals International Limited, established in 1903 and headquartered in Middlesex, England, is a manufacturer of premium seals, wipers, and bearings for the fluid power industry. The company’s products include rod seals, single and double-acting piston seals, and static seals. Its rod seals prevent leakage from hydraulic cylinders, and single and double-acting piston seals are designed to maintain fluid pressure within cylinders. The company provides sealing technologies for construction, mining, and industrial machinery industries. Its materials range from armorlene PTFE to elastomers, and it also provides CAD, design information, and fluid compatibility guidance services.

These differences are small, but generally speaking, the more blades you have, the more stable your wind turbine is. On the other hand, a turbine with fewer blades will be more efficient when it comes to actually generating power.

Hi-Tech Seals Inc. is a manufacturer of sealing and gasket components established in 1990 and headquartered in Edmonton, Alberta, Canada. The company’s products include a wide selection of o-rings, seal kits, and gaskets. It offers products fabricated from BoKure urethane, KasPex PEEK, and RyFlor compounds. The company primarily serves clients in the oil and gas, water treatment, and aerospace sectors. It also offers custom molding services, in-house rapid prototyping, and optical measurement inspections.

Again, at the scale we’re talking about, these are not make-or-break variations. But if you’re having a hard time choosing between one model or the other, you can use these marginal differences to help you decide.

When the sun comes out, carbon fiber still has an important advantage. Namely, that carbon fiber is resistant to damage from UV rays, even over the course of decades.

Too low of a pitch and the narrow blades won’t turn in normal wind, too high and the effects of drag are maximized, severely curtailing efficiency.

Plus, since drag is partly a function of size, the impact of adding more blades to a turbine is not an issue (up to a point).

We believe that the most important choice is switching to wind power in the first place. The type of turbine you get, the number of blades, all of these other things do make a difference in helping you maximize your system.

Residential turbines are smaller and lighter than commercial ones, which means that the cost difference of shipping a three or eleven blade turbine is negligible.

Carbon fiber is ultra-strong and lightweight, making the wind turbine blades better able to withstand damage from storms and debris. If you live in an area where a storm can arise quickly, you know how quickly things can get bad.

Our team has decades of experience experimenting with, designing, and testing all sorts of blade types for your wind turbine. We want to bring that knowledge to bear to help you become an informed wind power customer.

First and foremost among those is shipping weight. If you’ve ever seen a train rolling past with multiple cars loaded with individual turbine blades, you can imagine how inefficient the logistics of larger, more complex turbines would be.

Sometimes getting the most out of your wind turbine can come down to the finer details. Gains or losses in efficiency at the margins can add up, even for something as basic as the blade type for your wind turbine.
