Winter storm, no solar with panels covered with snow, and PW2 batteries draining down, now at 2 percent, Concerns?

We are experiencing severe winter storm up in Edmonds/Seattle over past 6 days with more snow on the way. I have been unable to charge the PW2 batteries over past three days, with more than 1 foot of snow covering them with temperatures in teens to twentys, and with yet another dumping of snow scheduled this afternoon. I had my PW2 batteries lower limit set at 5 percent in self-powered mode, but they continue to draw down, and are currently showing only 2 percent remaining. I am worried the batteries will drain down to zero, and what that might do to them. Any thoughts. I will be contacting Tesla-Energy to register my concern but thought the PW2 community might have some feedback/thoughts. I sure wish I had a safe and expedient way of getting the snow off the panels, as we do have good sun right now. Thanks for any input.

Maybe turn them off?

yea i would switch them off until you are producing solar again.

this was my biggest concern in the winter. i bought a roof rake (snowbrum and a 27 ft fiberglass extension pole). haven't had to use it yet because we've had an unusual lack of snow this year.

Well things have gotten worse and batteries now at 0 percent. I talked with my PW2 installer, who said I shoulld be OK in backup mode, which I am now. Hopefully I will be able to get some feedback from TeslaEnergy today. This weather system is nothing like I have ever experienced, since moving here in1985, and we are projected to get more snow every day this week.

Thanks @ripatriot, I just ordered from with 30 ft extension pole. Wish I had prepared for this earlier like you had. Still snowing like a banshee, and will take another 3 days before delivery, but I will be prepared next time.

@Tesla-David, I've been reading about your winter weather.
I imagine the roads are horrible and just a slip away from
an accident. Stay safe. Let me know how the snow rake works out.

Here in North TX I finally produced 50kw. 1st time this year.

@nwfan, great to hear from you, and I am completely envious. We are recovering from the worst Winter Snow storm in more than 50 years. I have had zero solar production for last 4 days, with my two PW2 batteries drained to zero, but I have 10 of 55 panels partially cleared today, and will be getting some solar, and the batteries are now charging, so hopefully they weren't damaged by this storm. We have only produced 24 kWh's so far this month, and would normally be averaging 19 kWh/day, so this is extremely unusual. The side streets are impassable and we have hills getting out to major passable streets. Tried to make it to store yesterday in our 85D and it was no go getting up the hills in our MS, so had to turn around and head back home. Will try again today and see if we can make it to the store as supplies getting low. Doubt the snow rake will get here in time to make much of a difference. We have never experienced anything like this and normally don't get much snow in the lowlands, with most snow going to the Cascade Range where it is needed for water supply.
