Saharan Dust

Post by EA6LE-ONE »

Yesterday afternoon we've been hit by the Saharan dust and everything is hazy today. The solar output is lower right now and I will try to post in the next days a shot of the power generation for general info.


This is picture of the sun this morning:

Found a similar issue with the bushfires in Australia in December, at least a 50% drop in solar output due to smoke.

Two years ago, Kilauea volcano erupted and we had 100 straight days of fine particulate matter in the air. Solar harvest was attenuated 35% overall, with some days as much as 90%.

The fire in the Columbia Gorge a few years back was terrible. It was started by a kid who threw a smoke bomb down a draw on a hiking trail. In the end huge amounts of forest land was torched in OR and WA (crossed the Columbia), many homes lost and a few lives as well. Many days the sun was blocked out like in your picture. It stunk, literally. Solar was way reduced like rayson mentioned during that eruption. Our livestock suffered. To blow your nose was scary. Fire fighting resources were stressed for anything else.

Anyway I hope your thing blows by soon. Doesn't it suck to wear a mask at home?

The air quality is not bad. The sand is more at the high altitude, some coming down and we have low visibility at about 1/2 mile. The solar production is kinda OK, maybe about 10% off. I think there is some indirect sunlight reflected by the dust that hits the panels as well. Don't see any deposit of dust on the panels yet. I will report in the next days with the experience.

That Saharan dust plume isn't projected to get this far west. But I have seen reduced output, maybe 10% or so, because of smoke from wildfires. Several are burning in Arizona as I write. Recently saw a forecast from NWS that uses one of their new updated icon set. We've dealt with wildfires before, but this is the first time I've seen "areas smoke" in our forecast!

We were in the SAZ (Smoke Affected Zone) for ten days of the Bush Fire (190,000 acres and almost out) that was about 20 miles downwind of us. Visibility in the afternoon was typically 1/2 mile. Solar output was reduced ~10-15%.
