Technical specifications

 

 
 
Type
Darrieus- Vertical Axis  (VAWT)
  
 

Rated power

Is the power output of the turbine as measured at a wind speed of 11m/s (24.6mph) using the IEC 61400-12-1 power performance standards.
Rated power
1.7 kW
  
 
 
Swept Area
78.5 ft²
  
 

Total Height

Total height of the system, measured from the foundation to the highest point of the system
Total Height
26ft / 41ft / 61ft
  
 
 
Cut in Wind Speed
3.9 m/s – 8.7 mph
  
 

Survival Wind Speed

The maximum wind speed at which the wind energy system should continue operating.
Survival Wind Speed
53.6 m/s – 120 mph
  
 
 
Rotor Width
8.9 feet
  
 

Rotor Height

The distance between the base and the top of the blades
Rotor Height
8.9 feet
  
 
 
Weight
297 lb – 135 kg
  
 

Grid Connection

Being interconnected to the grid is important as it will allow you to sell your excess electricity to the utility and to have access to financial incentives.
Grid Connection
230V-250V
  
 
 
Expected Lifetime
20 Years
  
 

Braking System

Ensures safe operation of the turbine when an unusual situation or excessive wind speeds are detected.
Braking System
Electric
  
 
 
Annual Energy Production
2000-4000 kWh/year
  
 

Self Supporting Monopole Options

This type of tower offers a less intrusive solution to guyed-wire towers. The different tower height options facilitate the process of obtaining a building permit as they can be used following the height restrictions. The availability of higher towers will allow the system to reach higher wind speeds and generate more power.
Self Supporting Monopole Options
15ft / 30ft / 50ft
  
 
 
Inverter Certification
UL1741,CE
  
 

Certifications

UrWind is currently working towards obtaining the respected SWCC (Small Wind Certification Council) certification
Certifications
SWCC Application Pending
  
 
 
Warranty
3 Years
  
 

Extended Warranty

UrWind offers an extended 5 year warranty at an additional price.
Extended Warranty

Type

VAWT are turbines that have a vertical axis of rotation. Darrieus turbines use a lift-based design like traditional horizontal axis wind turbines.

Rated power

Is the power output of the turbine as measured at a wind speed of 11m/s (24.6mph) using the IEC 61400-12-1 power performance standards.

Swept Area

Refers to the area delineated by the wind turbine’s rotating blades. In general terms, the higher the swept area, the greater the electricity production capacity and the greater the turbine’s size.

Total Height

Total height of the system, measured from the foundation to the highest point of the system.

Cut in Wind Speed

The wind speed at which the UrWind O2 will start generating electricity and powering your building with green energy.

Survival Wind Speed

The maximum wind speed at which the wind energy system should continue operating.

Rotor Width

Refers to the diameter of the cylinder traced by the rotation of the blades.

Rotor Height

The distance between the base and the top of the blades.

Weight

The weight of the standing wind energy system excluding the foundation and the tower.

Grid Connection

Being interconnected to the grid is important as it will allow you to sell your excess electricity to the utility and to have access to financial incentives.

Expected Lifetime

The designed lifetime of the turbine per IEC 61400-2 ed.2 standards.

Braking System

Ensures safe operation of the turbine when an unusual situation or excessive wind speeds are detected.

Annual Energy Production

The energy of the UrWind O2 will be vary depending on the wind resources at the installation site.

Self Supporting Monopole Options

This type of tower offers a less intrusive solution compared to guyed-wire towers. The different tower height options facilitate the process of obtaining a building permit as they can be used following the height restrictions. The availability of higher towers will allow the system to reach higher wind speeds and generate more power.

Inverter Certification

The UrWind O2 inverters comply with North American UL1741 standards. The UL 1741 certification is necessary for a grid connection.

Certifications

UrWind is currently working towards obtaining the respected SWCC (Small Wind Certification Council) certification and is listed as having an "Application Pending".

Warranty

A 3-year warranty is included with the UrWind O2

Extended Warranty

UrWind offers an extended 5 year warranty at an additional price.
