WC-vs-IstaBreezei700

Let's compare the Wind Catcher to an IstaBreeze i700 

Left: Wind Catcher. Right: IstaBreeze

We've chosen IstaBreeze because it's a reputable brand-name turbine.

Power Curve

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 the Wind Catcher is not spinning to protect itself. 

IstaBreeze has more than 3x maximum power output compared to Wind Catcher

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 will you be able to utilize a large power output. 

Daily production 

Looking at the energy production per day for various wind speeds, it's evident that the Wind Catcher produces more energy up till 7 m/s. 

For 4 m/s average wind speed, the Wind Catcher produces almost 3x the of energy! 

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.

In Denmark, where we build the 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 built to have good performance in average conditions - and not just in the most windy days. 

Capacity Factor

How many days a year your turbine will be generating its nameplate capacity is called the capacity factor. 

Wind Catcher has a super high capacity factor due to its very large rotor area

We've used the Istabreeze i700 power curve for the comparative calculations, Weibull wind distribution with a skew factor of k=5.0. - The skew factor is for a 24h period. Verified experimentally at our test-site.
