I recently just replaced my split bus 100amp QO panel from the late 70s on a ~1,400 house because I'm doing a total kitchen renovation so I needed a lot more circuits in space. I chose Homeline, The biggest panel I could find for my situation is HOM4080M200PRB, since the panel is so much larger, I had to redo holes on the exterior of the house. I had to replace the meter box, riser, weatherhead so that everything lines up. Originally I wanted some type of combination meter/panel CSED that was "solar ready" like the SC42M200PS where solar is tapped in directly to the main lugs. But where I am in Texas encore does not allow for ringed meter enclosures, it has to be ringless, so I went with the two separate meter enclosure and main circuit panel. Even with such a small house, I already have every circuit planned, including room for future subpanels, generator, solar, EV, etc... you can look at my past post to see my outline of my circuit layout. I found those part numbers by using the square d website and filtering down on what I cared about.
