December PV starting off crappy again.

[Nobodybusiness]

Well, with a 30kw array received 10kw yesterday and about same today.

Not quite enough.

Sincerely hope this December is not like last year.

My 13.6 kWp array saw 4.4 yesterday and 3.9 so far today. Not good indeed, but better than nothing, some “free” power is better than none.

Rained there all day too huh?

Rained most of the solar day yesterday, did let up after 4pm or so and the evening was hit or miss and just overcast. Today is just overcast so far. Rain forecast for tomorrow again…

Last 2 days with the next 9 days showing 90% overcast or rain.

It's not about the kW's you receive it's about how many hours you receive them

True it’s free but about 70kw less than what I need per day.

It's not about the kW's you receive it's for how many hours you received them

Panel voltage is almost max as soon as the sun comes up at 7 ish.

On clear sunny day I get power from 9-3.
Before and after almost nothing.

The amps really start peaking between 10-2.

 

[SeaGal]

I was just joking about how many hours you got 10kW for

I know. ?
Was just trying to give some insight into production at this site.
See if others had similar production.

Isn’t that the truth!!

You and me both.

Rain and/or clouds the past 3 days here. Good thing we aren't off grid.

I was hoping to get the posts for our pergola/solar panel mount put up this past week. I picked up the lumber last week, and it is now sitting under a tarp in the rain. I won't be able to get back to it for at least 6 - 8 weeks.

Agreed! With a 14.5kw array, have dropped from 40kwh/day during November to 9.5, 8.0, and 3.7kwh today... December is usually the very worst for my location.


Deep clouds, rain!


and there's no end in sight....


AGH!!!!!!!!!!

 

[timselectric]

Yup
December sucks. Not looking forward to January, either.
I'm going to throw a bunch of panels on the ground, in the back yard.
What the hell, it can't get worse.

I’ve got 1 more MPPT Channel I can put 12 more panels on but I would have to do what you said.
Just lay them on the ground.

I doubled the amount of panels I had and still sucks!!

Looks like the same forecast as my house.

Just frustrating..?

I'm just going to parallel more strings onto the existing MPPT's.
Overpaneling, to infinity and beyond.

That’s a good point.

I have 10 455w Solarever panels sitting in my shop.
Need 14 to max out the channel.

Doubt they would let me order 5 not to mention might get damaged with that few.
