Hmm not sure exactly. I just calculate my monthly earnings from the miners. I cannot export in array c as it's completely off grid. Also exporting in VA is not really worth it.

Yeah the snow sticks. I have to go outside with a broom to clear it off. Luckily the panels for array c are bifacial. So they pull in a little energy from the back. So I can still pull in a few hundred watts even with snow covered panels.
