More data provide a broader comparison, not a guarantee of greater accuracy. Both reports are estimates: they cannot fully represent local obstacles and turbulence, and do not replace on-site measurements.
Take a look inside the extended report
See what the full analysis includes: turbine comparisons, climate data,
station observations and wind adjustments in one PDF. No purchase is needed to view the sample.
The report gives you an initial, data-based estimate of wind potential at a specific location. It helps you look beyond manufacturers' headline figures.
No. Both reports provide estimates for initial site screening. Neither replaces on-site measurements or engineering design. Buildings, trees, turbulence and installation conditions can affect actual energy production.
The free report uses long-term climate averages from the Global Wind Atlas (GWA) to estimate wind potential and energy production. The paid, extended report also includes hourly weather station data, seasonal production, a wind rose and adjustments for wind direction variability and gustiness. Station data are an additional comparison, not measurements taken on your site.
A valid promo code gives you the same full report at no charge. Select "I have a promo code", complete the form and enter your code in the last step. We will email you the PDF.
No. The free report requires email confirmation, not an account or a payment card. One free report is available per verified email address, and marketing consent is optional. You can also buy an extended report without registering. An account is useful for multiple locations and report history.
For the free report, first confirm your email using the link we send. We then generate the PDF and send it as an email attachment. Paid reports are generated after payment and can be viewed in your browser, downloaded and delivered by email. Extended reports ordered with a promo code are delivered as PDFs by email only.
