Silentwind Small Wind Turbines

Silentwind is a Portuguese company with German management that was established in 1993. They have 30 years experience in the field, and their first work focused on creating low noise rotor blades. If you’ve heard of people happily replacing their OEM or other noisy blades, they probably bought Air-X blades from Silentwind.

Because of Silentwind’s success with their quiet wind rotors, they decided to manufacture their own wind generators. They introduced their first model in 2010. Silentwind offers three models: Silentwind Windgenerator 12V, Silentwind Windgenerator 24V, and Silentwind Windgenerator 48V.

All three models have basically the same specifications. The Windgenerator 12V has a rated voltage of 12V, the 24V has a rated voltage of 24V – you get the idea. The generators come with what Silentwind describes as an external hybrid controller for wind- and solar-energy with multi-function display and integrated electronic/manual stop switch.

Some more specs:

• permanent magnet-generator with 420 watts output
• very good start-up performance due to low cogging torque at 2,2m/s wind speed
• universal application for low, middle and high wind

The part that stands out with these generators is the blades: Silentwind create their blades differently than other manufacturers. Most blades are made using methods that minimize production time, usually involving injection molding. The problem is that low quality blades will degrade under UV exposure, which makes them even noisier than they were when they were brand new, as well as introducing the risk of fracture.

You definitely don’t want a fractured blade on your wind generator. Silentwind blades are handmade using high tensile carbon – they are hand laminated, UV-resistant, and low weight, all of results in a high-quality, long-life blade.

These generators are a low noise, durable, low maintenance products. For more information see the Silentwind website, or talk to your local dealer.
