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!
