How to design a single slope shed for good lighting

Single-faced greenhouses have good daylighting, which not only increases daytime daylight, but also provides a source of heat for night-time greenhouse temperatures. In order to make the daylight in a single-faced shed, the following points must be made in the design: (1) The orientation to the shed must be oriented toward the south, and if it is east or west, it should not exceed 15. (2) Shed film: Choose a plastic film with good light transmission and good insulation, such as polyvinyl chloride film without drip, long life without drip film, etc. (3) Front slope width: Face width: The horizontal projection width of the front slope surface preferably accounts for more than 2/3 of the total width of the greenhouse, is too narrow, has less light during the day, is too wide, and has much heat dissipation at night. (4) Shelter angle: The front slope should have a reasonable shed angle, which is generally 23 to 25 in Shandong, Hebei and other provinces. Shed surface is designed to be arched. (5) Skeleton: The shading of the skeleton should be reduced as much as possible. For this purpose, the framework is preferably replaced with a steel truss or a suspended beam instead of a multi-column bamboo-wood skeleton. (6) Shed distance; Before and after the two rows of greenhouses should be kept a large distance, so as not to shade. The spacing is generally not less than 6-8 meters.
