Question 1

Is wind or solar better for my home?

Accepted Answer

It depends on your location. Solar works best in sunny regions with 4+ peak sun hours per day and available roof space. Wind is better in consistently windy areas (average speeds above 5.5 m/s) with open space for a turbine. Most homeowners in suburban or urban areas benefit more from solar, while rural properties with strong average winds often get better returns from small wind turbines.

Question 2

How much does a solar panel vs wind turbine cost?

Accepted Answer

Residential solar typically costs $2.50 to $3.50 per watt installed, so a 6 kW system averages $15,000–$21,000 before incentives. Small residential wind turbines range from $3,000 to $8,000 per kilowatt, making a 5 kW turbine roughly $30,000–$50,000 installed. Solar is usually cheaper per watt and has lower maintenance costs, while wind turbines can produce more energy per installed watt in very windy locations.

Question 3

Which is more efficient, wind or solar energy?

Accepted Answer

In terms of raw conversion efficiency, wind turbines (35–45% of Betz limit) convert more of the available energy than solar panels (15–22% efficiency). However, what matters for homeowners is capacity factor — how often the system actually produces power. Solar has a higher capacity factor in sunny climates (18–25%), while wind turbines often sit at 25–35% in good wind but drop sharply in calm conditions. The more efficient choice depends on your local weather patterns.

Factor	Solar	Wind
Best location	Sunny, 4+ peak sun hours	Open, windy (5.5+ m/s)
Install cost	$2.50–$3.50 / W	$3,000–$8,000 / kW
Lifespan	25–30 years	20–25 years
Maintenance	Low (no moving parts)	Moderate (mechanical)
Noise	Silent	Audible (varies)
Space needed	Rooftop ok	Usually 1 acre+
Peak production	Midday, summer	Night/storms, winter
