I Screwed up (Vent Post) (System Size Post)

I got and installed 2700w of panels and a 20kwh battery - I live in WA

Honestly, I thought that it would generate a ton more than it is.

I was always surprised with my 600w array on top of my camper how many watts I'd pull in on a given day, even when it was cloudy out. Usually 200-300w.

But on cloudy days, I'm only pulling in like 300w or so with this big array!

Could I use more panels? Yeah, I could fit 2 or 3 more panels in making it 3600w, but that doesn't solve the whole issue - Plus I can't seem to find the same panels anywhere - It seems that they got replaced with a different model. If I add panels of a different voltage rating, won't that throw things off pretty badly? (Existing, 6x Canadian solar 450w)

Was it a whole waste of time? No, Not really. It was fun to install and I learned a lot, and I am offsetting... some... energy.
