I do not see how reflection from a solar array could be a "menace" to your neighbors, unless they are flying around in a helicopter.

The reflection from a solar array cannot not be any more menacing then windows. If they do have issues, it is other issues, Envy, TechnophobiaMetathesiophobia. What ever it is, it is their issue, I would not make it my issue by taking ownership of it.

Agreed, my guess is Envy.  We're all familiar with the old term "keeping up with the Joneses", and of course if you can't afford to, then you try to hold the Joneses (or whomever) back.  

Maybe they're just Republicans, they're afraid of everything.

Like trying to get ahead, not by improving oneself but, by knocking everybody around them down.  AKA obstruction.

Just give a look at the news. Kindly also read this article.

With a high pitched roof and an even higher sun, it is possible, however I doubt that it's nearly as bad as they claim, and planting some fast growing shrubs should fix the glare issue (it looks like that's already being done). 

Bear in mind the sun MOVES, and is only in the same place twice a year.  So it's only going to happen for a few minutes a day for a few days a year when the sun is in JUST the right place. Also, most solar panels do have a textured surface which will diffuse reflected light reducing it's intensity. 

Of course some folks will complain about anything, and I still think it's a matter of the "Joneses" and maybe a hungry lawyer (that's a pretty fancy house in the picture). Next thing they'll be complaining about the reflection off the windshield of his Mercedes.

I've had solar panels on MY roof for 8 years now and never a complaint from my neighbors, and they're a whole lot closer than the ones in the article.

Coating the cells to absorb more/reflect less light is good, but the glass needs to be coated as well. I understand some manufacturers do this.

I remember when Ted Kennedy and others were objecting to the placement of a wind farm off Cape Cod, because he claimed they would "spoil the view".  https://en.wikipedia.org/wiki/Cape_Wind

All they have are complaints, no facts established.

It is like a rerun of the Tweety killer argument against wind power. The argument was irrational and fell apart when the facts where examined.

Well, both of you can be right. But I have started this thread to know how much is reflected and how much is absorbed and radiated as heat. So far, there is no clear conclusion on this matter.

Only to you.

There is a conclusion, but it WILL vary accordingly to the panel in question, temperature, and its angle to incoming light. It would be easy enough to determine the light striking the panel, and the light reflected. The amount converted to electricity can also be determined. The balance is absorbed, and will ultimately be radiated/conducted/convected away (pick one or more).

Glass reflects ABOUT 10%. PV panels today are up to ABOUT 20% efficient. That leaves ABOUT 70% which is absorbed and then dissipated one way or another.

I say ABOUT. If you want a hard and fast number under test conditions, contact a manufacturer. I dare say each one will give you different numbers.

So, yes, the conclusion is not "clear". It depends on conditions.

I dare him to quantify "clear" [biggrin]
