I tried it but it was not enough to me.
What I need is the average wind speed for long-long from past, time minimum 2 years and more..
Do you have any database?
Thank you: Viktor Solti

Dear Windy, my name is Viktor Solti and I develop, produce and sale middle size wind turbines. I have started in this business 1,5 years ago, my company at this moment is a startup (www.windymove.com).
For any selling I have to know the average wind speed on my client's location. Could you inform me about average wind speed on your website datas continously?
thank you: Viktor Solti
