Wind report for your location

The report is a quick, affordable first assessment before buying a turbine. It combines climate data, weather station observations and turbine power curves to help you compare options. It does not replace on-site measurements or engineering design.

Treat the figures as estimates based on the stated data and assumptions, not a promise of production. Local buildings, trees, terrain, turbulence, mounting height and equipment condition can change actual performance. A promising result is a reason to investigate further, not a guarantee of a successful investment.

The predefined groups include Ista Breeze, Ecorote vertical-axis turbines, Feng-Teng 2–20 kW and Feng-Teng 30–100 kW. After logging in, you can also use your own set of turbine power curves.

Yes. Open My power curves after logging in. Save one active set of up to 6 turbines, entering power in kW at 1 m/s intervals from 0 to 15 m/s. The server checks required values, zero power at 0 m/s, non-negative values, large drops before peak power and a maximum 10-to-1 ratio between peak powers. You can edit or delete the set and select My turbine set when generating a report.

No account is required to buy a single report or use a valid promo code. An account provides report history, report credits and custom turbine power curves.

Turbine power curves, climate-based wind speed distribution, annual energy estimates at selected hub heights, station-based hourly analysis and seasonal production, a wind rose, site and station maps, explanations of local obstacles and adjustments, and data sources and limitations.

A single report costs PLN 15.99 including tax. Enter your email, select the location and turbine group, and accept the required terms and immediate-delivery consent. Choose Order and pay to proceed to Stripe. Alternatively, enter a valid promo code and choose Order with code. Codes are subject to their expiry dates and usage limits.

Generation begins automatically after payment or acceptance of a valid code. Paid reports can be viewed in the browser and downloaded as a PDF. Promo-code reports are sent as PDFs by email only; check your spam or promotions folder as well. Account reports can be downloaded, emailed and accessed later in report history.

Climate data describe longer-term wind potential. Station-based results use hourly observations from the surrounding area, generally referring to about 10 m above ground, with an allowance for wind variability and gustiness. These sources use different assumptions and may represent different conditions. Stations can be far from your site. The station scenario is not a guaranteed lower bound, a formal P90 estimate or an on-site measurement.

A power curve shows instantaneous turbine power in kW at different wind speeds in m/s. Annual energy depends on how often those speeds occur at the site. Rated power alone does not tell you how much energy a turbine will produce.

The speed distribution shows how often different wind speeds occur. Combining it with a power curve gives an energy estimate. The wind rose shows how frequently wind comes from different directions. This helps you consider obstacles upwind of the turbine, but does not model turbulence around individual buildings or trees.

No. It is an informational and analytical report, not a technical design, bank-grade audit, guarantee of yield or standalone basis for an investment decision. Assess local obstacles and consider on-site measurements before committing to an installation.

Create an account and use report credits. Packages contain 1 report for PLN 15.99, 5 reports for PLN 59 or 10 reports for PLN 99, including tax. They are useful for installers, consultants, farms and businesses screening multiple locations.
