Wind turbine technology
What type of turbines are these?
Why VAWT instead of traditional turbines?
VAWTs work better in low and turbulent winds, are quieter, safer, and more suitable for cities.
What capacities are available?
From 100W up to 5kW per turbine.
How much power will it generate?
Generation depends on wind speed. On average, it can cover 20–60% of a home’s energy
needs depending on location.
What is the minimum wind speed required?
Typically around 2–3 m/s.
What is cut-in wind speed?
The speed at which the turbine starts generating power—very low compared to conventional
turbines.
Can it handle high wind speeds?
Yes, turbines are designed with safety braking and protection systems.
Does it work in low-wind areas?
Yes, VAWTs are designed for low and variable wind conditions.
Is it suitable for Indian climate?
Yes—designed for heat, dust, rain, and monsoon conditions.
Can it work during monsoon?
Yes, monsoon winds actually improve performance.
RESIDENTIAL & SITE QUESTIONS
Can it be installed on a house?
Yes, on terraces, rooftops, or ground-mounted setups.
Is it suitable for apartments?
Yes, subject to space availability and society permissions.
How much space is needed?
Very little—much less than solar panels of similar capacity.
Does it need open land?
No, it can work in urban environments.
Can it work near buildings?
Yes, VAWTs perform well in turbulent wind.
Is it safe for homes?
Yes, safety is a core design feature.
Will it damage my building?
No, vibration and load are minimal when installed correctly
Is it safe for children and pets?
Yes, slow rotation and enclosed designs make it safe.
Does it require fencing?
Not usually for rooftop installations.
Can it be installed in cities?
Yes, many installations are urban.
NOISE, SAFETY & DESIGN
Is the turbine noisy?
No, it is very quiet—suitable for residential areas.Noise Level is less than 40DB
How loud is it?
Typically below ambient city noise levels.
Can it be used near hospitals or schools?
Yes.
Is it bird-friendly?
Yes, slow-moving blades reduce bird impact.
Does it spin very fast?
No, it rotates at safe, controlled speeds.
Does it look bulky?
No, designs are compact and modern.
Do you have aesthetic models?
Yes, including flower-shaped urban turbines.
Can the color be customized?
In some cases, yes.
Does it cause shadow flicker?
No, this issue is common only with large horizontal turbines.
Is it suitable for public places?
Yes, parks, campuses, and resorts use them widely.
ELECTRICAL & SYSTEM QUESTIONS
Is it grid-connected or off-grid?
Both options are possible.
Can it charge batteries?
Yes.
Can it work with solar panels?
Yes, it is ideal for hybrid solar + wind systems.
What inverter is required?
It depends on the individual. A suitable wind or hybrid inverter.
Do you supply controllers?
Yes.
Does it look bulky?
No, designs are compact and modern.
Do you have aesthetic models?
Yes, including flower-shaped urban turbines.
Can excess power go to the grid?
Yes, with net-metering approval.
What happens in very high winds?
The system automatically protects itself.
Is lightning protection included?
Yes, grounding and protection systems are recommended.
Can it power EV chargers?
Yes, as part of a hybrid or storage system.
Can it provide backup power?
Yes, with batteries.
PERFORMANCE & EXPECTATIONS
Will it reduce my electricity bill?
Yes, significantly over time.
How long does ROI take?
Typically 4–7 years depending on usage and wind conditions.
What is the lifespan?
20+ years with proper maintenance.
Does it work at night?
Yes—this is a major advantage over solar.
Does it work in rain?
Yes.
Can it run ACs and pumps?
Yes, with correct sizing and inverter.
How do I choose the right size?
Based on your energy consumption and site wind profile.
Can one turbine power a full home?
Usually combined with solar or grid for best results.
Does it generate power daily?
Yes, whenever wind is available.
Is wind reliable?
When combined with solar, it is highly reliable.
PRICING, SUBSIDY & ROI
