—90-day modelled production—Specific productionIllustrative reference system, not a recommendation.
Modelled solar irradiation is not actual usable or exportable electricity. Shading, roof geometry, orientation, tilt, equipment losses, temperature, dirt, snow, downtime and inverter/system limits can affect production. Grid availability, export restrictions and curtailment can affect use/export without changing incoming irradiation.
Average wind at 10 m
—at 10 mWind ≥ 2.5 m/s
——GreenPie uses ≥2.5 m/s here as a preliminary screening threshold, not as a universal turbine operating threshold.
Indicative modelled estimate, not an onsite measurement. Actual turbine production can be materially affected by buildings, trees, terrain, obstacles, turbulence, hub height and mounting position, installation quality and other local conditions GreenPie cannot fully model. Consider a professional site-specific assessment before installation.

Detailed analysis
Choose a 2, 5, or 10-year detailed Wind or Solar analysis. Neither path models turbine energy, cost, payback, or recommends a turbine.
Long-term analysis uses ERA5 historical reanalysis for a consistent multi-year comparison.

Residential small wind
A cautious screen for the residential 1–6 kW class. It does not choose a turbine and does not estimate energy, savings, or payback.
Turbine simulation
Choose a documented turbine and hub height. Results use hourly ERA5 wind and the published curve; this is not a recommendation.

Long-term solar analysis
Run a separate historical solar-resource and modelled PV-production analysis for the selected location and configuration. The preliminary 90-day preview above is unchanged and is not annualized.
The selected horizon is shared by Wind and Solar. Longer horizons are not claimed to be proportionally more accurate.
Modelled solar irradiation is not actual usable or exportable electricity. Shading, roof geometry, orientation, tilt, equipment losses, temperature, dirt, snow, downtime and inverter/system limits can affect production. Grid availability, export restrictions and curtailment can affect use/export without changing incoming irradiation.

Your household
Compare a repeating 12-month household load with modelled monthly solar production over the same 24-month resource window.
Values are monthly kWh from the observed 24-month resource pattern, averaged into one representative year.

Wind is shown as a resource in metres per second. Converting wind to household energy would require a specific turbine power curve, which is not modelled in this phase.
Solar and Wind resource context
This compares monthly wind with normalized solar yield over the same 24-month window. It is a resource relationship, not your energy use.
Each series is scaled to its own maximum (100%). These percentages are not energy or wind-speed percentages.

A ~24-month monthly correlation is descriptive only; seasonal structure dominates and correlation is not causation.
Turbine data foundation
Technical documentation varies by model. Inclusion here does not qualify a turbine for GreenPie energy calculations and is not a recommendation.
No annual energy, cost, payback, or turbine recommendation is shown here.
