I have 30 panels that are ground mount. When it snows, then I go out and scrape the snow off the panels. It is a pain to do, but if I don't do it then power production is zero or close to it until the snow melts. The 12 panels that are on the roof I just leave until the sun does its job. Sometimes it takes days before the panels start to produce again.
I am off grid for 9 months of the year but still have trouble with Nov-Jan. CMP has a good deal going for me now, cross my fingers. They do not charge anything when I am disconnected. Then to reconnect they charge $12 plus a minimum $22 a month plus usage fees. My power bill for Nov-Jan last year was $137. So, I figure that $137 per year for electricity is not that bad.
Without Solar my electric bill would have been around $2400 a year. I think that getting off my but and scraping the panels when it snows is painful but worth it.
I am going to put up another 12 panels this spring or summer to see if I can be totally off grid. I do have a generator, but CMP is cheaper than running it.
