If installing a small wind turbine for site assessment is what you are intending to do, you will need to keep it up for at least one year, just like an anemometer. In that case, why not just put up an anemometer tower with multiple levels of instrumentation, so you can extrapolate data that can be used for any wind turbine, rather than take the performance inherent in a specific small wind turbine, then try to extrapolate that data to use with anything else?
You neglected to mention if the site was for a single residential installation or a potential multiple turbine, large scale wind farm. If a wind farm, you will need multiple anemometer towers for 2-3, possibly 5 years. A single residential installation, coupled with net metering and some state level grant money (which CA has) would be well served by a professional wind site assessment, not a temporary wind turbine installation. We use the average of four different data sets, coupled with an actual site visit and some wind turbine production modeling. If you have to have actual onsite data, install an anemometer system and leave it up for a year. It will probably be less costly and far more accurate than a tower of the same height with a small turbine on it.

I told him that he needs to move beyond downloading "maps" showing the m/s contours at some altitude (at a fairly coarse scale), and get a small turbine on the actual site and take some actual data (at the appropriate height). I think I read somewhere that there are companies that will provide that service for a fee. They truck the system out to the site, erect it, install the data logging, and come back at some point in time and break down the system and truck it home. They share the data with us and possibly recommend products compatible with the wind data. If this is true, could folks give the contact info for these companies? I would really like to work with an engineering company, which doesn't have an agenda to sell us product, but if that won't wok, I'll settle for "pre-sales technical support". - Peter Peter T.
