Hi all,
The snow around here has piled up enough that a strong blowing from the south drifted snow against the bottom 20% of my array. This happens maybe once or twice a year and I trudge out into the field and move the snow. I didn't have the time this week to deal with it and because it was super sunny I thought there was no rush. Then last night I found my bank SOC was sitting at 57%. Obviously not happy about that!
I checked my Outback controller and it said that for last week I only got under 20AH. After clearing the snow away the next morning I got 334AH, which has got to be a record for me as I've never let the banks get drained down so low
I don't understand the physics of why ~20% reduction in capacity resulted in 10 fold decrease in collection. Can someone help me understand what happened? Obviously I'm not going to blow off cleaning the panels the next time this happens.
Thanks,
Steve
