Since you showed me your curve, I was going to show you mine but is it not as pretty. Cloudy days have been killing my production and this last month will dig into my credit with the power company, taking 30-40% of what I built up over the summer. But when the sun is shining, we are getting as much as a good summer's day. (fixed ground mount) The cool air helps a lot.

In a Rorschach sort of way, yesterday was a Seattle Skyline kind of day here, 16 kWh on 7.8kW array:

Feast your eyes on this curve:

Not bad for a 4.5kW array in February. Still able to charge my Tesla in winter. Gotta love solar power :)

How do we make that peak flatten out and last about 5 hours? ;)

Gosh, here I was thinking we will have pictures of Funky & Outrageous Solar Panel installations of or Nekkid Inverters (SUBS) having it out with Controllers (DOMS).

Naked, no cloths on,
Nekkid, no cloths on and up to something...

This caught my eye because my wife call this stuff 'Jeep Porn', 'Car Porn' or 'Charging Porn' when I stare intently on the screen...
She says it's cheaper than meth, but after the last couple months I'm not so sure anymore! ;)

Wait till you get one of these...

This is what happens when you get "clipped". It's pretty rare, but it happens.

I want enough panels the profile looks like I need roller lifters to say on the 'Cam' lobe!
I get this next bunch of panels bought & installed, the new (to me) batteries installed, I think the next car will be an EV.
No sense in not taking advantage of the racking & wiring infrastructure that's already here with some updated panels and use the crap out of it...

250w panels going in where 60 & 100w is now should make a big difference...
 
SMH ......

I'm with you, I don't see the 'Manhood' part, must be the Asperger's...

But I would like to have a nice flat peak at 100% production from 8AM to 4PM,
And enough charge controller & battery there wasn't any need for 'Clipping'.
Plug in EVs to absorb the production, not have to watch consumption at the shop, have 100% of what we needed in the winter

With the BYD batteries, I'm seriously considering the electric tractor this year.
Batteries were my problem the first time around.
Application bit me in the butt...

When spring breaks, you only have so many days to get crops in,
And between gear reduction to make torque, and the wrong battery it just wouldn't do the job.
One full sun day charging, then 3/4 of a days work, then another full day charging I lost 1-1/4 days for every 3/4 day of work.
(Nobody wants to swap a 1,600 pound battery in the middle of the day even if you have a spare, which I didn't)

Now I have enough battery!
When they aren't in the garden, they power the house and other stuff, but can be racked in the tractor during 3 seasons.
Winterizing an electric tractor would be taking the LFP battery pack where it can't freeze!
I'm good with that.

Picking up a tractor trailer load of panels next week, that will solve a crap load of issues I have in the winter, and FINALLY solve the winter low production issues in winter.

I'd like to have Will's curve, but at about 13kW peak...!

My goodness! I cannot wait to see some of the projects you accomplish with THAT!
 
And here I thought I would see pictures of the new Tesla Hedgehog system... 9.75 kWh of sweaty power.
