The front slope is covered with heat insulation at night, and the single-slope plastic greenhouse, which is surrounded by walls, east, west and north, is collectively referred to as solar greenhouse. The prototype is a single-slope glass greenhouse, the front slope of light-covered material with plastic film instead of glass that evolved into the early solar greenhouse. Sunlight greenhouse is characterized by good insulation, low investment, energy conservation, very suitable for China's underdeveloped rural use.

Solar greenhouse performance

Energy-saving solar greenhouse light transmission rate is generally 60% to 80% or more, indoor and outdoor air temperature difference can be maintained at 21 to 25 degrees Celsius.

1. Daylight greenhouse lighting

On the one hand, solar radiation is the most important source of energy to maintain daylight greenhouse temperatures or maintain heat balance; on the other hand, solar radiation is the only source of photosynthesis for crops.

2. Sunlight greenhouse insulation

Sunlight greenhouse insulation by the insulation structure and the activities of insulation is composed of two parts. The front slope of the insulation material should be flexible materials to easy to sunrise after the put away at sunset.

The development and development of new front roof insulation materials mainly focus on the requirements of mechanized operation, cheap price, light weight, anti-aging and waterproofing.

The solar greenhouse is mainly composed of three parts: the wall, the rear roof and the front roof. It is the "three elements" of the solar greenhouse. The front roof is the whole surface of the greenhouse. During the daytime, the roof is covered with plastic film. When the light is weakened, the plastic film is covered with the activity insulation to strengthen the greenhouse insulation.

Sunlight greenhouse can also be configured top window system, roll film system
