Let's compare Wind Catcher to an IstaBreeze i700
Left: Wind Catcher. Right: IstaBreeze
We've choosen IstaBreeze because it's a reputable brand-name turbine.
IstaBreeze has a larger peak power output, however, it's at very high wind speeds. So high wind speeds in fact, that we've actually made sure that Wind Catcher is not spinning to protect itself.
IstaBreeze has more than 3x maximum power output compared to Wind Catcher. It's clear that only if you're in the windiest of places you'll be able to utilize a large power output.
Looking at the energy production per day for various wind speeds, it's evident that Wind Catcher produces more energy up till 7 m/s.
For 4 m/s average wind speed, Wind Catcher produces almost 3x the of energy!
In Denmark were we build Wind Catcher the average wind speed is ~5m/s (12mph). Denmark is a windy place, but you'll often not be camping in the most extreme wind conditions - that's why Wind Catcher is build to have good performance in average conditions - and not just in the most windy days.
How many days a year your turbine will be generating its nameplate capacity is called the capacity factor.
