True Energy Transition:
Storm-Tested Small Wind Turbines & Photovoltaics
Efficient wind turbines from 300W to 100kW, PV trackers, and IoT off-grid systems for households, agriculture, and businesses. Maximum reliability in any weather.
From Hard Testing on the North Sea Coast to Compromise-Free Professional Systems
When we planned a heat pump for our house right behind the North Sea dike a few years ago, it quickly became clear: the electricity demand is enormous. So why not make sensible use of the coastal wind that is available around the clock?*1
As an engineer and hobby pilot, I am well versed in mechanical engineering, electrics, and aerodynamics. However, our two-year test phase with countless models on the market quickly revealed a massive industry problem:
Our Consequence: We sat down with a former Danish quality manufacturer whose measurements were honest. When a severe autumn storm with hurricane-force gusts over 150 km/h tore our test system apart, we seized the opportunity: we meticulously analyzed the weak points and decisively reinforced the entire mechanics of the series.
The result is extremely resilient systems that are proven to withstand wind forces over 12. We provide you with seamless facts: exact Rayleigh yield forecasts, transparent noise curves, and free structural calculations for foundations.
Secure true independence – all the way to well-thought-out systems for crisis-proof emergency power supply.
