Just realized my off-grid system in rural Oregon has a major flaw no one talks about

I've been running 400 watts of solar for 2 years now, but last month's winter storm taught me something. The panels stay covered in snow for days and my battery bank drained to 40% before I could clear them. Is it better to mount them steeper at 60 degrees and lose summer output, or stick with 30 degrees and deal with winter losses?

I angled mine steeper after the first winter and it helped a ton.

Heard a contractor say angle makes or breaks it with snow load.

Yeah, steeper angle makes a huge difference in snow country.
