In systems with AGM batteries we like to have close to a 1:1 ratio of solar panel watts to battery bank amp-hours.  Too little solar, and your batteries won’t get up to a full charge as often as needed for healthy operation.  Not enough battery amp-hours, and your charge controller will throttle down the solar input to keep from over charging full batteries which means your panels aren’t fully being utilized.  This Class A motorhome hits the sweet spot with 1280W of solar and 1200Ah of battery capacity.  (This does not apply to lithium batteries, because lithium batteries don’t need a regular charge.  You can install as many amp-hours of lithium batteries as you can afford and it doesn’t matter how much solar you have on your roof.)
