In the end, I did not go ahead with this as I felt our site was ok and did not justify the cost and time involved. This seems to have been validated as our 10 kW Bergey generated 13.5 mW in the first 12 months of operation, which was about 15% less than our 'best estimate' prior to install. Our 'best' week (to date) was actually w/c 6 Jan 08, when we generated 478kWh.
Info on the Annometer received from James Jarvis in 2006.
Attached are two photos of the solar powered self-contained data logger. The only things not shown are the anemometer and the cord between the PV panel and the yellow box.
In the waterproof case there is a solar charge controller, 7 amp/hour AGM battery, and all associated fuses and connectors. All you will need to do is mount the solar panel and anemometer and turn it on. Unless the panel gets covered in snow it should have enough power to run "forever." The battery will wear out after about three years, but only costs about $18 USD and is very common.
The price for this setup is as follows:
$225 Data Logger w/temperature sensor
$18 128 megabyte SD card
$15 USB SD card reader
$330 solar powered self contained (includes all hardware described above)
We'll include whatever length anemometer cable you need for free. If you need a lock for the case, solar panel mount, or weather proof enclosure mounting hardware we can provide that for a nominal fee.
The weight of this package is approximately 16 lbs. Global Express Mail shipping is $75.60. FedEx international priority (48 hours) is $161. We currently have the package in stock and can ship on Monday.
Let me know if there is more information I can provide or if you would like to proceed.
Thanks and have a great weekend,
