What is a Yin-Yang solar greenhouse?

The yin and sun type solar greenhouse is to borrow (or reuse) the back wall of the traditional solar greenhouse on the north side of the traditional solar greenhouse, and add a slope greenhouse of the same length but with the lighting side facing north.

A greenhouse with lighting facing the sun is called a sun shed, and a greenhouse with lighting facing away from the sun is called a shade shed.

The shade shed of this type of greenhouse takes advantage of the open space that must be left in the general layout of the traditional solar greenhouse to ensure the lighting of the solar greenhouse behind it, thus improving the land utilization rate.
