The sunlight greenhouse is referred as the energy-saving sunlight greenhouse and is also called as the warm shed. It mainly consists of the fence wall, back-roof and front-roof which are referred as "three elements" of sunlight greenhouse. The front-roof is completely the lighting surface of greenhouse and is only covered by the plastic film for daylighting in daytime. When the outdoor lighting weakens, promptly cover the plastic film with the activity heat preservation quilt in order to enhance the heat preservation of greenhouse. 

The sunlight greenhouse is a kind of greenhouse without heating indoors, which achieves the heat accumulation and release by absorbing the solar energy through back-wall to maintain certain temperature indoors and meet the growth demand of vegetable crops. 

The sunlight greenhouse is used for the overwintering cultivation in cold region with simpler facilities by fully utilizing the solar energy, while the sunlight greenhouse of cultivation facilities where the fresh vegetables are produced owns the distinct Chinese characteristics. 

The sunlight greenhouse is characterized by good thermal insulation, low investment and energy-saving, which is very suitable for the usage in China's underdeveloped villages. 

Performance 

The light transmittance of sunlight greenhouse is over 60%~80% in general, and the indoor and outdoor air temperature difference could keep about 21~25 ℃. Daylighting of sunlight greenhouse 

On the one hand, the solar radiation is the most important energy source of maintaining the sunlight greenhouse temperature or keeping the heat balance; 

On the other hand, the solar radiation is also the unique light source for photosynthesis of crop. 

The sunlight greenhouse takes the hot galvanizing thin-wall steel pipe as the arch materials, with the following advantages: high strength, strong wind and snow-resistance ability, good rust resistance, high light transmittance and convenient operation management, with service life reaching 10-15 years. It is an ideal selection for wide farmers due to low income and high income. Qingzhou Haoyang Greenhouse Engineering Co., Ltd. provides each user with high-quality product and high-efficiency service.
