Probably true but nobody that sells them commercially has published a dba level (that I could find). Also, the so called "almost silent" ones I looked at were in the $1500-$2,000 range -------- for 400 watts max @ winds around 30 mph.
How much "solar" can one buy for $1500-$2000 with 200 watt panels selling for ~150-$170 today.
