Sunlight panel greenhouses are a replacement for traditional plastic film and glass greenhouses. They are mostly of the Venlo type (arch shapes are also available), often featuring multiple spans and ridges. They have a modern appearance, stable structure, and aesthetically pleasing design with a smooth visual flow. They boast excellent insulation, moderate light transmission, multiple gutters, large spans, high drainage capacity, and strong wind resistance, making them suitable for areas with high winds and rainfall.

Structural Features

Connection MethodMultiple individual greenhouses are connected by gutters and other components to form a continuous large greenhouse structure. This connection method provides a more spacious and open internal area, facilitating large-scale agricultural production and mechanized operations.

Covering MaterialCommon covering materials include glass, sunlight panels, and plastic film. Glass offers good light transmission and is aesthetically pleasing and durable; sunlight panels provide strong insulation and high impact resistance; plastic film is lower in cost and easy to install, allowing for selection based on different needs and crops.

Frame MaterialHot-dip galvanized steel pipes or aluminum alloys are commonly used, offering good strength and corrosion resistance. They can withstand significant wind and snow loads, ensuring the stability and safety of the greenhouse structure.

Performance Advantages

High Space Utilization RateThe interior is free of or has few pillars, resulting in an open space and large usable area. This allows growers to arrange planting and equipment as needed. It is suitable for modern planting techniques and equipment, such as vertical cultivation and soilless cultivation, improving land utilization and output.

Strong Environmental Control CapabilityEquipped with an advanced environmental control system, including ventilation, shading, heating, cooling, and irrigation systems. The coordinated operation of these systems allows for precise adjustment of environmental parameters such as temperature, humidity, light, and carbon dioxide concentration within the greenhouse, creating suitable conditions for crop growth, enabling year-round production and high yields.

Good Insulation PerformanceDouble or multi-layer covering materials and effective sealing measures are used to reduce heat loss and improve insulation. In winter, this effectively reduces energy consumption and heating costs; in summer, shading and ventilation provide effective cooling, keeping the greenhouse temperature within a range suitable for crop growth.

Strong Disaster ResistanceThe overall structure is sturdy, and compared to single-span greenhouses, multi-span greenhouses have stronger wind and snow resistance. The framework is carefully designed and calculated to withstand significant external loads, better protecting crops and facilities during severe weather conditions such as typhoons and blizzards.

Applications

Vegetable CultivationCan be used to cultivate various vegetables such as tomatoes, cucumbers, and peppers. Precise environmental control enables counter-seasonal and year-round production, improving vegetable yield and quality to meet market demand.

Flower CultivationProvides a suitable growth environment for flowers, benefiting their growth and development, improving quality and yield. Often used for high-end flowers such as roses, lilies, and Phalaenopsis, meeting market demands, and also suitable for flower research and seedling cultivation.

Fruit CultivationSome fruits with higher environmental requirements, such as strawberries and blueberries, can also be grown in multi-span greenhouses. Adjusting temperature, humidity, and light conditions promotes fruit growth and maturation, improving yield and quality, and extending the harvest period.

Agricultural TourismWith its attractive appearance and diverse planting content, multi-span greenhouses are often used in agricultural tourism projects. They can be developed into agricultural sightseeing parks, ecological restaurants, and science education bases, attracting tourists to visit and experience the fun of agricultural production, stimulating local tourism and integrating agriculture and tourism.

Covering Material

The top covering uses a UV-resistant outer layer and a dew-proof inner layer of polycarbonate hollow panels. The surrounding walls are typically made of polycarbonate hollow panels or glass. Depending on the regional climate, in colder areas (such as Jilin and Heilongjiang), the north wall may use an insulated composite panel, and sliding windows can be installed to increase ventilation.

Technical Parameters

Wind load resistance: 0.6KN/M2, 10-level wind resistance; snow load resistance: 0.5 KN/M2; greenhouse permanent load: 15KG/M2; maximum rainfall capacity: 140MM/h.

Main Configurations

Computer monitoring system, automatic control system, internal and external shading systems, roof and side window systems, evaporative cooling pad and fan systems, infrared heating systems, etc.

Greenhouse Specification

Standard greenhouse specifications have a span of 9.6 meters or 12.8 meters, a width of 4 meters, an eave height of 4.2 meters, and a ridge height of 5.2 meters. Span and width can be customized.

Greenhouse Applications

This greenhouse is mainly used for ecological restaurants, display and sightseeing, scientific research experiments, demonstration and promotion, high-efficiency planting (fruits, vegetables, flowers, trees, Chinese herbal medicine, etc.), agricultural product sales, and high-efficiency breeding (aquaculture, livestock, insects, etc.), and integrated industrial cycles.
