Dear All,<br>
<br>
Thank you very much. This is all useful stuff. I guess binning isn't
in the engineering culture over here in the UK in the same way it is
in the UK. We tend merely to use hourly weather data to do
simulations and can take design data from CIBSE (most of the time).<br>
<br>
I'll definitely undertake these exercises. In the mean time, I wrote
some very crude vba to step through the weather data and calculate
its effect on battery charge which I'll be happy to share once I've
tidied it up a bit.<br>
<br>
Cheers<br>
<br>

8322 for 95% percentile of 8760 hourly data? Am I missing
something here ? The only wrinkle in respect to wind speeds is
that the hourly values are spot measurements, and not
time-averaged over the hour.

I usually take this kind of data for granted (our industry has
been commoditized so much!).
<br>
<br>
Statistics not being my strong point, does anybody know of any
good web resources for working out percentile data of various
weather characteristics? I have hourly data available and would
like to undertake the task in excel (or openoffice).
<br>
<br>
Thanks
