The very simple answer is you must have a battery system to complement the solar system or you're just losing power again when a cloud comes and decimates your household production. The electrical inertia must be held at a nice constant.

Thanks, that makes a lot of sense too. I didn't have a sense for how much power would fluctuate, but it makes sense that it would almost _need_ to fluctuate well below capacity. If it didn't, it would mean that in full sun you'd have built your solar array well _over_ capacity, which would be inefficient in a different direction.
