Solar greenhouse is very popular in agriculture today

In the modern times, people prefer to eat off-season vegetables and fruits around the year. A series of solar greenhouse production systems are in place to ensure continuous production of fresh vegetables year round today. In China, solar greenhouses are widely used in the regions north of Huai River, such as Shandong, Liaoning, Hebei, and Gansu provinces, and the Beijing area. Furthermore, today, the world is facing an energy crisis and “global warming,” and using solar greenhouses can help curb these problems.

In a traditional solar greenhouse, greenhouse frames can be made from bamboo, steel, or a mixture of both. The structural alterations include changing the angle of elevation of the back roof and the light-harvesting angle of the transparent front roof, and increasing the wall thickness of the side and back walls, as well as the horizontal shade length of the back roof. All of these measures improve light collection and insulation efficiency of the greenhouses. The space inside the greenhouse becomes much more open. These design changes result in energy savings and increased productivity. This style of greenhouse is very popular in the northern China today.

In the world, glass greenhouse becomes very popular in farming for a long time, in which steel frames and pillars were installed to support the structure. Glass is the major covering on the roof and the light-harvesting roof had a curved surface. The insulation consisted of non-transparent materials such as straw blankets or bulrush mats. The inner space of the greenhouse was small, and the roof was low. The light-harvesting surface area on the front roof was smaller than modern solar greenhouses, and the small angle of elevation of the back roof resulted in absorption of a very limited amount of solar radiation during the winter. The wall and the back roof had a very low capacity for insulating and thermo-protecting. These first greenhouses still needed to be heated by traditional methods to produce warm-season vegetables during the winter. These structures were generally used for early spring production or for the preparation of seedlings on a very small scale.

In the modern agriculture greenhouses, solar greenhouse is an important innovation in protected cultivation history, especially in this low carbon production era, which has many advantages in that they save energy, reduce pollution, and improve economic and social development. However, solar energy can be adversely affected by weather conditions. During the winter, the less solar radiation and the lower temperature will have significantly negative impact on the warm-season vegetable productivity in greenhouses. In that regard, innovation and optimization of the solar greenhouse structure needs improving in the long run.
