(Author here) My roof is full on both sides. There simply isn't any more room.

I do say:

> As solar panels increase in efficiency, it might be more sensible to replace the panels on my roof, or add some onto a shed.

Even in the darkest days of winter, they still generate something (unless they're physically covered in snow) - but they'd need to be 20x as efficient to power my typical winter usage.

Solar panels are already at least 20% efficient (most are better than that). I don't think they'll improve much beyond 30% within the next 20 years. Your 20x aspiration is of course technically impossible.

Did you DIY? Our installer basically only put panels on the sunniest sides of our home. I'm surprised you went with panels on all sides.

We didn't DIY. Our installer was happy to put the panels wherever we wanted.

Our roof is an even East/West split. So one side powers our morning and the other side our afternoon.

		It's really interesting that you still get a smooth production graph with east/west, I wasn't sure what that would look like. We have east and south and our peak production is when the sun is at the south-east, in the middle of the two faces. The east face production drops off from there on out until it's a fraction of what the south face is generating.
