snow on air-x blades

I have had my air-x land 12volt up since just before Christmas. I have seen snow sticking to the blades twice now. The first time it didn't last. At that time the blades were not turning. It seemed to melt off. Now the snow is staying on the blades and the wind is approx 15 to 20 mph.
Gusts are higher. The blades are moving slowly. I am not seeing the red light on the bottom of the turbine. Questions please. Is the snow going harm the blades? Warp or bend them? How bad of a factor will the snow play on the turbine output?
In northern new york, I'm expecting a lot more snow.
Appreciate any and all info.

  hi ray,

  sounds like you have some good wind resources there. i've had that same concern and found that armor all seems to help with those black plastic blades and car wax works well with aluminum blades.

 don't think the snow should harm them or warp them.

good luck, dave

Re: snow on air-x blades

My prior employer built windmills for severe climates (Alaska). They used a fairly expensive hydrophobic coating on their composite blades. Unfortunately I dont know what brand it was but you may want to try to search for it.

Re: snow on air-x blades

Hi Roy G.  I have had icing of my turbine (whisper 200) blades several times, without any damaging consequence, and did not find it necessary to shut down the turbines, since the ice took care of that task, and slows the turbine down to a crawl. I observed no imbalancing, mistracking, or vibration effects since the ice seems to distribute itself evenly on all blades at the same time.  The ice will evaporate directly without going to the water stage in a couple of days and more quickly when exposed to sunlight, as the blades are black in color and absorb some solar heat. Its just a nuisance effect from living in this colder climate. Wink (I do like the suggestions about hydrophobic and armorall coatings and will try this in the future. I tried paste wax on the blades with little or no effect.  Thanks all Smiley )

Re: snow on air-x blades

thank you, I will try the armor all on one blade. A friend suggested Rain-x. the stuff people put on car windshields. I will try that on number two blade.
I'll try different things just so i dont have to get up there and keep cleaning the blades. I dont want to ruin them. Any other suggestions?
