<font size="+1"><font face="Arial">I too have some experience with
Array Technology (Wattsun) trackers (customer systems and 3 here at
home). In the early days there were lots of problems with sensors aging
and causing the array to not track properly. Customer service was
always (and still is) exceptional. <br>
<br>
Those early problems have been resolved and now the product is robust.
My only minor issue is in low light conditions (like in the winter) the
rack will go clear back flat. The work around for here in snow country
is that I always add a toggle switch to the vertical actuator. I have
the customer shut the power off to the vertical actuator in the winter
at a steep angle to keep the snow sliding. Pole mounts work really well
in deep snow country and if the site specifics allow, I'll suggest a
tracker.<br>

P.S. Make sure you remind your customer to grease them at least once a
year.<br>

Y2K, that while troublesome, fully demo'd Wattsun's committment to
customer service. A year ago we installed 1 of the new and improved
design, and it has been flawless. Be sure to get the manual switch for
making tracking adjustments and so it can be set flat for
windstorms--just for hurricane insurance here in the east.

We continue to spec them for those sites with good E to W solar window.
With time of use net metering, they really make sense---so long as the
durability holds up!
