I'll second Jay's remarks. We had a 4 tracker system from 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!

Hi Carl,
On average its around a 15% winter and 40% summer increase in KWH.
That of course depends on how good your sun window is.
These numbers are pretty well published so you should be able to find
them for your area.
Reliability is pretty good, with great customer service if there is a
problem.

Hello Wrencjhes,
Happy Easter. May the Bunny bring you lots of goodies in your basket.
Two questions on the Wattsun AZ-225
1) What is the experience with reliability of these units
2) Any real world data for comparison of increased production from the
tracker versus a fixed ground mount at optimum tilt for the latitude.
Thanks
