Sunlight greenhouse.

The structure of the solar greenhouse is mainly composed of three parts: wall, rear roof and front roof.

1. The wall is divided into a back wall and two gables. The back wall refers to the wall parallel to the ridge of the solar greenhouse and located on the north side of the vegetable greenhouse. Gable refers to the walls on both sides perpendicular to the ridge of the solar greenhouse. The wall has three main functions: one is heat preservation, the other is heat storage, and the third is to support the rear roof and the front roof.

2. The rear roof mainly refers to the slope between the rear wall and the roof ridge, also known as the rear slope. It is made of materials with better thermal insulation properties. The main function of the rear roof is heat preservation.

3. The front roof mainly refers to the daylighting roof from the ridge to the greenhouse, also known as the daylighting roof. It is mainly composed of a skeleton, a transparent covering and an opaque covering. The skeleton mainly plays a supporting role, the transparent cover is mainly used for lighting, and the opaque cover is mainly used to maintain a reasonable temperature and humidity in the shed at night.
