The one thing that's inevitable when using PVC or fiberglass wind generator blades is that they're going to break at one time or another. If you're looking for solutions that are long term aluminum wind generator blades might just be the thing you're looking for.

Of course there are more reasons that aluminum wind generator blades are better, but we'll focus on durability for now.

Being made from aluminum these blades are not very prone to 'flapping'. If you have PVC blades or fiberglass blades on your wind generator right now you know what I'm talking about. Flapping is the blades moving back and forth while they're spinning around. This puts quite a bit of stress on the blades especially at higher wind speeds. This is one of the main reason why PVC and fiberglass blades fail.

With aluminum blades though, these problems simply do not appear. Aluminum is many times stronger and stiffer than either PVC or fiberglass. The other upside of aluminum blades is that they simply won't rust. This was something I was pretty worried about when I first learned that there were blades made out of metal.

The other thing I worried about was efficiency. These blades weight so much more than their PVC and fiberglass counterparts. The interesting thing about these types of blades is that they are quite a bit wider simply because the material is stronger. As we know, the amount of wind that the blades can grab directly affects their efficiency.

The two companies I've seen that sell aluminum blades: TLG windpower and windy nation both claim that their blades start up in as little as 2MPH winds.

While that's a bold claim, during my research I did find videos that support this. Due to the larger blade width these blades can start up in much slower winds. What does this mean for you? Well, it means you'll be generating power over a much broader spectrum of wind speeds.

So, why would you want to get a set of aluminum blades? Well, in the long run you'll save money because these blades are never going to break. They're more efficient than PVC or fiberglass blades, plus they have a start up speed of 2 - 3MPH. You'll save money in the long run and generate more power with less.
