I’ve actually been shocked by how little production drops during winter. For example, we Feb & March, our coldest months this year, we produced 1.75 MWh/month, which actually beats every summer month before it, and is only beaten by this August, which was our highest producing month ever at 2.04MWh. Most summer months before that were closer to 1.5. Only thing I need to do is clear the panels after it snows.
I think that if you’re comfortable doing it, go for it. If you didn’t have any experience, and are lucky enough to live near an avian vet, maybe it’d be good to have them do it once while you observe and can ask questions, but it sounds like you’d do fine as is.
