Bad days for Solar Production.

[Nobodybusiness]

15.8kWh today.

This is what kills me. If I could just average better I would be fine but when it’s crappy it’s really crappy.
Not just cloudy but rain.
We got like 2 inches of rain yesterday and today.

Sunny and cold are fine. Rainy and cloudy are crap.

predicted to be somewhat sunny today, I was at least expecting to see it. Nope just solid clouds all day. at least it wasn't raining.
We had to use the honda 2200 last night for the first time this year...

we managed 1.87KWH!!!!

Yea. Weather prediction is like voodoo.

Another day of "supposed to be full sun was a bust full clouds. Only 23.7kwh from 57kw of pv. Battery is down to 34% tonight. Full sun forecasted for tomorrow......

Hopefully the sun happens for ya.

I at 68% so am in the same boat.

How does the rain get mud on panels on your roof!?!?!?!

They get dust an other small debris on them, then the drizzle mixed with it and it flowed a little way down the panel slope into a brown paste. I didn't take pics this time, but I think I have one from spring.

Here is before a rinse.

And then after.

It helps a bit. I get 5 to 10% power back when I hose them off.

 

[Reed Cole]

Most would classify that as grime rather than mud.

40kWh today. Lots of sun, batteries full.

There's hope!

You have seriously dirty air if that’s the type of natural accumulation you get in your panels-yikes!

had a minor earthquake (2.8) centered about 2 miles away yesterday
I guess it shook the clouds loose because today the sun came out for the first time this month

The world of dusty climates, no everywhere is green and rainy like the PNW.

Yes we do.

The climate here is very dry and warm. Any loose dust is easily blown around and can stay airborne for a long time without moisture to weigh it down. We also have a bunch of construction going on so we have more of the light grey dust from concrete as well. Then add in all the dying vegetation and it makes a nasty soup. I am just a few miles from the edge of the Mojave desert. Last year we also had a couple small brush fires, so there was ash in the mix as well.

Holy crap dude, my eyes, what is that thing???

 

[timselectric]

I can see it here, too.
It could be a great day.

You've got 2 suns... that's just greedy - send one of them over to the UK

 

[42OhmsPA]

I was cutting between buildings at work, not a cloud in the sky.
Sadly I haven't gotten the NE panels on the ground mount yet and my 5490w off poorly angle roof arrays are only producing 2480w 15 minutes before noon.
I'm missing out on some serious production, now I'm motivated to work in the cold after work ?

Here in dust-pit city, ... It's really wonderful. Your car gets polka-dot's when you get a light sprinkle, which is too often what we get. It leaves little dirt craters all over the panels. Figuring that must be awful, I clean my panels. I do not see over a 5% improvement, which I find really odd.

SUN! 180.4kwh today. I have 9 inverters of solar growatt 5000es, but I don't have all inverters installed, so have 6 inverters over paneled till I get more installed. Most of the day I had 500 amps of power going into the batteries.

Wow
I didn't realize how similar our systems were.

Uh, Oh, I feel a bragging rights competition is coming ?! Gonna motivate Tim to get all those panels up!

 

[timselectric]

I definitely need motivation.

Well, how about that, it just so happens they are my weather channel too

 

[B-Mod]

I am glad to see and follow another person with 5000ES 's. My 9 inverters will be all powered by 7s,2p 400 watt Bifacial panels. 6 inverters in one system and 5 more will be in another system but all sharing the eventually over 200kwh battery bank. Full electric house and shop, and 2 ev's.

We think alike, both sparky's too.

Exactly the same plan here, almost.
Planning on 6 and 2. Which should be enough, hopefully.
