This is somewhat out of my specific experience, but when we get snow, there a many things that *have* to get cleared, as our snow is usually very wet and heavy and often rained on while falling!

I'll back the not climbing on the roof part - but maybe long term planning could involve installing a platform so that you can safely access the panels for cleaning? A concept for everyone contemplating roof panels to consider?
"Can't reach" can mean many things. My first idea reading this, is that possibly when the snow is light, you could stand on a ladder and point a leaf blower at the panels? If you don't have a leaf blower, I would suggest you find one you could borrow for the first try?
I've successfully sprayed off the snow using a garden hose, but this is cumbersome and, depending on the depth of snow on the panels, can take up to an hour to complete.
We have a power washer. That may or may not work faster than the hose. However, power washers have to be stored where they won't freeze, so that needs to be kept in mind. Again, if you don't have one, I'd try to borrow one for a trial.
I've also thought of placing something like pipe heating tape below the panels, but I don't want to introduce thermal stress and cause the panels to crack.
I don't know the difference between pipe heating tape, and the specific roof/eves trough heating tape that my parents had. They had a section of north facing roof where some of the snow would melt and back up under the shingles because ice would form in the eves trough and not melt fast enough. Personally, I still would hesitate using it on solar panels without discussing it with the manufacturer.
It might help if you could attach a few photos, and certainly help if we had more of an idea of the closest distance you can get to the panels. As Hubby got older, he found accessing the chimney for sweeping harder and harder. He decided to splurge on scaffolding that is now permanently installed beside the chimney. Luckily it's mostly out of sight.
