[RE-wrenches] Wattsun AZ-225 reliability and Production

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!
