Solar comparison
Home Solar vs Small Wind Turbine: Which Renewable Energy Source Fits Your Property?
Compare residential solar panels and small wind turbines by energy output, cost, site requirements, maintenance, and which renewable source fits different properties.
Quick answer
What this comparison means
Solar panels are the better choice for 95%+ of US residential properties: they work in all 50 states, require minimal maintenance, have no moving parts, produce predictably, and cost less per kWh. Small wind turbines need consistent 10+ mph average wind speeds, 1+ acre of open land, tall towers (80–120 ft), and tolerance for ongoing maintenance. Only rural properties with verified wind resources should consider wind over solar.
Comparison table
| Factor | Option A | Option B | Why it matters |
|---|---|---|---|
| Site requirement | Any roof with south/east/west exposure (3+ hours sun) | 1+ acre open land, 80–120 ft tower, 10+ mph avg wind speed, no nearby obstructions | Solar works almost anywhere. Wind is extremely site-dependent. Most suburban lots fail wind requirements. |
| Energy output (5 kW rated) | ~6,500–7,500 kWh/yr (avg US) | ~5,000–18,000 kWh/yr (highly variable by wind resource) | Wind output varies 3–4x based on location. Solar is more predictable. |
| Upfront installed cost | $11,000–15,000 (5 kW solar, $2.20–3.00/W) | $25,000–50,000 (5 kW turbine + tower + foundation + electrical) | Wind costs 2–4x more upfront for the same rated capacity. |
| Cost per kWh (lifetime) | $0.06–0.10/kWh | $0.10–0.30/kWh (depends heavily on wind resource) | Solar's per-kWh cost is more predictable and usually lower. |
| Maintenance | Minimal — wash panels annually, inverter replacement after 10–15 years | Annual — blade inspection, bearing lubrication, guy wire tension; potential gearbox/alternator repair | Wind turbines have moving parts. Budget $500–1,000/yr for maintenance. |
| Permitting | Standard building permit; HOA solar access laws protect in most states | Zoning variance often required; height restrictions; neighbor objections common (noise, views) | Wind turbines face much stricter local zoning. Many municipalities ban or severely restrict them. |
| Best for | Any homeowner in any state — the default renewable choice | Rural properties with verified wind resource (10+ mph avg), 1+ acre, and tolerance for maintenance | For 95%+ of US homes, solar is the clear winner. Wind is for specific rural situations. |
Data Sources
This comparison uses state electricity-rate ranges, local incentive context, net-metering rules, and solar production assumptions informed by NREL PVWatts-style modeling. Final quotes, utility tariffs, and interconnection rules can materially change the economics.
Assumptions
Payback and ROI are directional estimates, not financial advice. They assume typical residential roof conditions, stable household usage, currently available incentives, and separate treatment of battery backup value, financing costs, and installer-specific add-ons.
