25kw solar output

[point1st]

I would consider a good design something that meets or exceeds what the customer asked for to begin with, not a series of excuses why it hasn't or doesn't. As I said, from the systems I looked at, from the links supplied, they had no problem in reaching 90-92% on a sunny day in March not May. Maybe May would bring higher results then? When a customer asks for a Mercedes and you bring him a Chevy it would be logical that he might be upset. I'm using 4kwh a month minimum in winter months.

The intent of optimal AC(inverter) to DC (panels) ratio is to optimize cost, not to be able to squeeze out every single KWh during some hours when panels produce more power, i.e. mid May afternoon.
Most PV designers use 1.25 ratio.

That might be the case. What is to be optimimized is for the designer
to decide. The real world situation might be more concerned with existing
equipment and contract limitations, clouds, carbon footprint, and entirely
avoiding initial and ongoing hookup to fossil fuel suppliers. Ground or roof
mount will make it more complicated. A DC:AC ratio of over 2 has been
very successful here for many years. Bruce Roe

Yeah I agree with you.

BTW my PV system has 72 panels; 52 LG Neon 2 330 and 20 Suniva 260 panels with Enphase IQ7 microinverters. Public view of the system with ability to see historical data: https://enlighten.enphaseenergy.com/...87477/overview
My DC nominal rating is 22.4KW and AC is 17.04KW.

I am sorry I am not here to spam I'm genuinely here to join the forum since I live in a house that is 100% powered by Solar energy. Sometimes I need help with solar panels and batteries that's why I join here, I apologize and I will make sure to keep in mind to not post unnecessarily!

Instead show us pictures and figures of how you manage 100% powered
by Solar. The hardest part here is doing HVAC by solar, I manage it by the
brute force method of a big solar array. Bruce Roe

Welcome to the forum, no need to apologize. Spammers often do this to "get their foot in the door" and then edit them later to include advertising links. Since you made several of them, that's what I thought was happening.

.. . . I will have to install another Sol-Ark12k in parallel . . .

I very much doubt that that will change anything.

I have a 9880 watt (STC DC) system. I have a 5200 and 3500 watt inverter; total 8700 watts. I have seen them maxed out exactly twice in the past 11 years, and both times it was right after it rained (panels clean/cool) and when the sun came through a hole in the clouds (cloud lensing.) It did not last long - as soon as the panels warmed up it dropped off to about 8000 watts.

The rest of the time they peak around 7500 watts. That means I regularly see a peak of 76% performance from panels to AC. In your case that would be about 19kw - which is exactly what you are seeing.

I have already proven my point. The company informed me that a sol-ark 12k will do 9k to grid/ house and 3k to the batteries. For 2 in parallel that would be 18k to the grid/ house and 6k to batteries if they need to be charged. I ran my batteries down overnight a few times and the arrays are putting out between 22k and 24k when it is also charging the batteries at same time. It is possible that if the inverters would allow higher that the arrays would do more. Now I need to get the installer to replace my undersized inverters with 2 that will allow the arrays to reach their potential. I have included a screenshot so that you can see with your eyes.Screenshot_20220414-141548_PV Pro.jpg
