Planning and Zoning Commission <br />Minutes <br />January 8, 2019 <br />22 <br /> <br />Because of the visible observations I made, literally today as I drove around, that is what I was <br />looking for. <br />Mr. Corley said if that observation point was listed as not visible, it is safe to assume there would <br />not have been a glare issue to begin with. <br />Mr. Wingo said that is correct. I will point out, though, if you look at the study, even if you <br />removed all of the trees and you looked at just the actual glare analysis itself, none of the glare <br />identified in the report is substantial enough to provide damage to the eye or significant after- <br />vision effects. If there were no trees at all, as far as the health and safety of the public goes, you <br />would still have a safe installation. <br />MR. CORLEY: Thank you. <br />Mr. Benshoff: Is it true there is a supplement to the glare report where the observation points <br />from which glare was reported were field checked and that showed no glare from those OPs? <br />Mr. Wingo: I do not know when that --I would have to look and see when that was performed, <br />based on the current observations I made today. <br />Mr. Benshoff: It was performed in the fall. <br />Mr. Wingo: It was a revision to this report and added as a supplement. Yes, that is correct. Okay. <br />Yes, that is true. <br />Mr. Litaker understands that the solar panels absorb light. What are the surfaces made out of? I <br />know it is not like chrome, it would not be very reflective. <br />Mr. Wingo: It is a form of glass, depending on the maker, three to five levels of coatings that go <br />on top of that to prevent reflection. The whole intent is to absorb as much as possible, so you are <br />trying to prevent the amount of solar energy that is reflective off the panel. <br />Mr. Litaker said when you say coating, is it like window tinting type coating. <br />Mr. Wingo said no, it is more chemical type coating. He is not an expert in that, but based on the <br />literature and the research for this particular topic, that is what they base their software on, the <br />Sandia National Lab software on, which now owned by FORGE. <br /> Mr. Pinto asked if there are any panels that move. <br />Mr. Wingo: There are, I would have to look to make sure, but I am pretty sure there are two of <br />them that are single tilt. When you have single tilts, you do not have any glare. So if they are <br />tilting --so you have three and one of them are tracking.
