    Did they do the Glint Avoidance study ?

    Put a row of those in, and you could burn the whiny neighbors house down, and sterilize the lawn, getting rid of all that noxious green stuff !

    Every HOA I've ever run into was all about conformity on "little houses made of ticky tacky and they all look just the same" ( Pete Seegar )

    Just today I felt a Martian Heat Ray from reflected sunlight off of a large tinted window. It's intensity stopped everyone who wandered through it. The location was smack in the middle of an area normally occupied by a children's swimming pool, but the pool had been drained and a skating rink temporarily installed on the same spot. The distance from window to focal point was about 50 feet, but it was very warm.

    Let's hope they got that right! That is about $275,000 in Chevy Volts sitting there.

    It's a single axis tracker, I believe, rotating about the z axis. Look at the pole just below the array at the mechanism. It would just about have to operate with a horizontal planar rotation to have cars parked under it. Assuming that it's in Michigan somewhere, its tilt is much less than latitude.

    I would be curious as to how they came up with projections of its output. You can run single axis tracking at X degree tilt through PVWatts, but that assumes that the axis of rotation is in the plane of the array*, and this one clearly operates differently. It seems to me that using numbers from a PVWatts run at 10 or 15 degrees tilt with single axis tracking would predict a much greater increase in output as a result of the tracking than will be realized with this setup. I hope they did their homework correctly.

    * you can prove this to yourself very easily. Do a PVWatts run at zero degree tilt, fixed, and then do one at zero degrees tilt, single axis tracking. If it rotated about the z axis there would be no difference in output.

    About the HOA's. I seem to have read they have no say over Federal laws about renewable energy.Our HOA said no outside clothes lines untill they were supplied with federal laws stating they could not interfere with any renewable energy production unless they could PROVE it would cause physical harm or health issues.

    what federal law states that?

    I dont' think this is true as
    federal law also protects free speech, but HOA's prevent free speech all the time, no big USA flags, no signs, etc.

    Property law is generally done at the state level. I know that CA and AZ have laws you describe.
