>> the WallMill™ product compared to rest?
WallMill™ specs are same as the other 1.4kW kits it's just that the WallMill™ mounts to the wall. The WallMill™ has some more flexibility to have a taller mast. Wallmill™ is usually used on prefab concrete buildings, like strip mall, or warehouse construction.
A RoofMill™ is still better for most residential sites that do not have enough acreage for a tower. Also for sites that do not have ideal facing roofs AND no acreage. The RoofMill™ is our best selling system and is preferred for most farm or residential sites.
In an ideal site the RoofMill™, peak ridge of the roof should go perpendicular, or at a right angle, to the predominant wind direction of a site. Thus on most days the wind will come in from the broad side of the roof, using it as a wind concentrator.
Thanks, Samuel H
