The fall-off from August to December is remarkable - but the total output is still a meaningful amount of power considering we just had the winter solstice in the Northern Hemisphere.
Reading through your post again it sounds like your goal is to be 100% self-sufficient even in the winter months. It looks like the cost per watt has sort of leveled off over the past six months. Is that what you are seeing when pricing the next array?
Sure is... I was expecting some but not this much.
I would like that, but at night I would need a massive battery bank to make that a reality. But during the day the plan is to have 100% solar providing power.
