When I first started looking into home renewable energy for clients—mostly property owners trying to cut their power bills—I assumed solar was the obvious answer for everyone. Panels are sleek, quiet, and there’s a rebate for them everywhere. Why would anyone mess with a wind turbine?

Three projects and one very expensive mistake later, I learned that a home wind turbine can actually outperform solar panels in the right conditions… and in the wrong ones, it’s a complete money pit.

Here’s the thing: there’s no one-size-fits-all answer. Your decision depends entirely on three factors: your average wind speed, your property’s setbacks, and your energy consumption pattern. Let me walk you through the scenarios so you can figure out which camp you’re in.

Scenario A: The Grid-Tied Home (Most Common)

If you’re already connected to the grid and just want to offset your power bill, solar is almost always the better bet—unless you live in a consistently windy area.

The solar case: Solar works reliably from 8–10 AM to 4–6 PM, depending on the season. You can size a system to cover 80-100% of your annual usage with net metering. A typical 6.6 kW system in a place like Perth (where I’ve sourced inverters for clients) costs roughly $6,000–$8,000 installed, including a goodwe inverter, and pays itself back in 4–7 years.

The wind case: A small residential turbine (1–5 kW) costs $4,000–$15,000 installed, but it only makes sense if your average wind speed is consistently above 10–12 mph (about 16–19 km/h) at hub height. That’s rarer than most people think. In suburban areas, trees and buildings typically drop wind speeds below that threshold.

“In my role coordinating energy solutions for homeowners, I’ve seen a lot of people spend $12,000 on a turbine only to discover their average wind speed is 8 mph. That system will never pay itself back.”

My advice for Scenario A: Go solar unless you have documented wind data showing 12+ mph averages and a clear, unobstructed site. A goodwe inverter on a PV system is a proven, low-maintenance solution. Wind adds complexity and moving parts that require more maintenance.

Scenario B: Off-Grid or Remote Property

This is where wind actually wins—or at least, where solar and wind work best together.

Off-grid systems rely on batteries. Solar alone has a problem: in winter (especially in northern latitudes), you get maybe 4 hours of solid sun. Your battery can only store so much, and if you have several cloudy days in a row, you’re running a generator.

Wind doesn’t care about clouds. If you’re in a windy corridor (coastal ridge, mountain pass, open plain), a small turbine can keep your batteries topped off overnight and during storms. I had one client in rural Missouri who used an ESS-Missouri-portal-approved setup: a 3 kW turbine paired with a cheap solar inverter (a powland unit, actually) and a battery bank. It kept his cabin running year-round, even through December.

The catch: You need space. Most turbines need a tower at least 30–50 feet high (clear of tree line), and your property lines likely have setback requirements. Tower+mounting can double your total cost.

“One of my biggest regrets: recommending a standalone turbine for an off-grid cabin without factoring in the cost of the tower. The client ended up spending $18,000 instead of the $13,000 I'd quoted. Should have included the 40-foot tower in my initial estimate.”

My advice for Scenario B: A hybrid system—solar panels (with a goodwe inverter) for daytime charging and a small wind turbine for night/winter backup—is the gold standard. Budget $10,000–$20,000 depending on your location. And get a tower quote before you commit.

Scenario C: High Energy Consumption (EVs, Heat Pumps, Workshops)

If your household uses 30+ kWh per day (think: two EVs, a heat pump, or a home workshop with tools running), neither solar nor wind alone will cover you without a massive installation.

Here’s where my thinking shifted: I initially assumed you just need more solar panels. More panels = more power, right? But the problem is physical space. A 10 kW solar system needs about 500–600 square feet of unshaded roof. Not everyone has that.

Wind has a better power density per square foot of land—provided you have the space for the tower and the wind resource. A 5 kW turbine in a good wind site can produce 15–20 kWh/day on average (more in winter). That’s roughly equivalent to 25 solar panels, but in a footprint about 20 feet wide.

“In March 2024, I consulted for a homeowner who had already maxed out his roof with 6 kW of panels but still needed another 10 kWh/day for his workshop. A 3 kW turbine on a 35-foot tower added that capacity without sacrificing any more roof space. Total cost: $9,500. Solar alternative: $12,000 for a ground mount (plus trenching).”

My advice for Scenario C: Start with a solar system sized to your roof space. If you still have a gap, and your property allows it, add a turbine. Don’t try to replace solar with wind for high consumption—it’s too variable. Use one to complement the other.

How to Figure Out Which Scenario You’re In

  1. Check your average wind speed – Use the National Renewable Energy Laboratory (NREL) wind resource maps. If you’re not in a “good” or “excellent” zone, wind is probably a bad primary source.
  2. Calculate your roof space – How many square feet of south-facing (north-facing in Australia) roof do you have? Divide by 15 (typical panel size in sq ft) = max panel count.
  3. Check your budget – Solar is cheaper per kWh produced in most locations. Wind makes sense only if solar is physically constrained, or if you’re off-grid and need seasonal balancing.
  4. Check your property lines – A wind turbine needs setbacks. Many towns require 1.5x tower height from property lines. A 50-foot tower needs 75 feet of clearance on all sides.

If you’re in Scenario A, get a goodwe inverter quote from a local solar installer. If you’re in B or C, have a conversation about wind. But don’t assume one is better than the other until your property tells you otherwise.
