Frequently Asked Questions.

Wind turbines use either the lift principle (like airplane wings) or the drag principle (wind pushing against a surface). Lift-based systems are highly efficient but require steady, high-altitude wind. Drag-based systems work better in turbulent, near-ground environments but traditionally have lower efficiency. novventos combines both principles—achieving higher performance in real-world, decentralized settings.

Vertical wind turbines perform better in turbulent, near-ground wind conditions common in urban and rooftop environments. Unlike horizontal systems, they don’t rely on tall towers or laminar airflow. The novventos naca.boost is specifically engineered for decentralized installations—making it ideal for businesses, communities, and off-grid applications seeking reliable, local power generation.

There are two primary vertical-axis designs:

Darrieus rotors, which use lift and require higher wind speeds, and

Savonius rotors, which use drag and perform well in turbulent, low-altitude wind.

novventos enhances the Savonius concept with airfoil-shaped elements, combining lift and drag for improved efficiency and broader operational range.

The naca.boost combines hybrid lift-and-drag aerodynamics, wind-accelerating housing, integrated solar panels, and intelligent software control. This enables high uptime, quiet operation (just 10 dB at 10 meters), and efficient energy harvesting even in turbulent conditions. It’s compact, visually unobtrusive, and engineered specifically for decentralized energy independence.

Wind and solar complement each other. When wind speeds drop, sunlight is often available—and vice versa. By integrating solar panels directly into the housing, nacaboost maximizes surface efficiency and increases annual energy yield. This hybrid system significantly improves uptime and reduces reliance on battery storage.

The key variable is the average wind speed at your site. In high-wind locations — coastal areas or exposed hilltops — a naca.boost vertical wind turbine will typically match or outperform rooftop solar in terms of annual yield and return on investment. In lower-wind areas, solar tends to deliver a stronger ROI on its own, which is where our sky.boost solar panels as stand-alone installations come into play. What makes the novventos approach compelling is that wind and solar naturally complement each other: when wind is low, sunlight is often available, and vice versa. The hybrid system provides a more consistent, year-round energy source than either technology alone.

The naca.boost StaticWings 3126 can generate up to 10 MWh annually per unit, depending on average wind conditions at the installation site. This output supports meaningful energy independence for commercial buildings, communities, or off-grid applications. A location-based wind assessment determines the precise expected yield.

Thanks to its hybrid wind-plus-solar design, naca.boost delivers highly consistent energy generation. Throughout the year, there are very few hours without either wind or sunlight. Intelligent load management optimizes performance across changing conditions, ensuring stable annual output and high operational uptime.

naca.boost wind turbines begins harvesting energy at a cut-in wind speed of just 3 m/s — a gentle breeze that many conventional turbines would overlook entirely. From there, output scales continuously with wind speed, reaching its rated peak at the optimal operating point of 13 m/s. At wind speeds above 15 m/s, the rotor management system automatically engages to reduce rotational speed, protecting the turbine's structural integrity while maintaining safe, uninterrupted operation. This wide operational window — from calm urban rooftops to exposed industrial sites — is one of the defining advantages of VAWT technology. 

Two variables drive the lion's share of your potential yield: local wind speed and solar irradiance. Of these, average wind speed has a particularly strong effect, since wind power scales with the cube of velocity — small differences in wind resource translate into significant differences in annual output.

As a general rule, sites with average wind speeds above 4–5 m/s and good southern exposure will see the strongest returns from a hybrid naca.boost system.

Peak output refers to the maximum power a system can generate under ideal conditions. However, real-world energy production depends on annual wind patterns and uptime. For decentralized systems, annual yield and consistency matter more than peak ratings—areas where naca.boost’s hybrid design provides a strong advantage.

The novventos battery.boost energy management system includes integrated storage starting from 15 kWh, expandable in 15 kWh increments to match your consumption profile. Whether you need a compact buffer for overnight use or a larger reserve for extended off-grid autonomy, the modular storage architecture scales to your requirements.

The best sites combine high average wind speeds and strong solar irradiance. Before installation, novventos recommends assessing your location using the Global Wind Atlas (GWA) for wind potential and the Global Solar Atlas for solar irradiance data. Together, these tools provide a reliable basis for estimating annual energy yield and return on investment at your specific site.

naca.boost is suitable for rooftop installations, ground-level sites, and even mobile container-based systems. Its compact design integrates easily into existing structures and landscapes. The unobtrusive form factor often simplifies permitting compared to large-scale turbines.

Off-grid installations can typically be completed in less than a day. The naca.boost system is designed with logistics in mind — its modular architecture is optimized for ISO container shipping, making transport straightforward even to remote sites. On-grid installations depend on local grid connection requirements and must be assessed individually. Please contact us for a site-specific evaluation and installation planning.

Yes — naca.boost wind turbines are compatible with both off-grid and on-grid configurations. There are no fundamental differences in the system hardware between the two setups; the main distinction lies in grid connection procedures, which vary by location for on-grid installations. Our team can advise on the right configuration for your site and energy needs.

Yes. The novventos system is built on a modular platform, allowing you to add capacity or move the installation as your needs evolve. Whether you're scaling up production or relocating to a new site, the system design supports flexible adaptation without requiring a full reinstallation.

Permitting requirements vary by country, region, and municipality. As a general rule, off-grid installations tend to face fewer regulatory hurdles than grid-connected systems. Since naca.boost is a close-to-ground installation — compact in footprint and visually unobtrusive — it often qualifies for simplified permitting compared to conventional wind turbines. We recommend contacting your local municipality to understand the specific requirements for small wind turbines and solar panels in your area. novventos can support you in preparing the relevant technical documentation.

The vertical-axis design already reduces wildlife risk compared to large horizontal turbines. Additionally, an optional protective rotor enclosure further minimizes bird strike potential. Its compact size and low-speed operation make it a responsible solution for urban and decentralized energy environments.

novventos wind turbines are exceptionally quiet — measuring just 10 dB at 10 meters distance, which is below the ambient noise level of most environments. All novventos products are fully compliant with European safety regulations for small wind turbines, covering structural integrity, electrical safety, and operational standards.
