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 boast a modern appearance, stable structure, attractive and generous design, smooth visual lines, excellent insulation, moderate light transmission, multiple gutters, large spans, high drainage capacity, and strong wind resistance, making them suitable for areas with high wind and rainfall.

Structural Characteristics

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

Covering MaterialCommon covering materials include glass, polycarbonate panels, and plastic film. Glass offers good light transmission and is aesthetically pleasing and durable; polycarbonate panels provide strong insulation and high impact resistance; plastic film is lower in cost and easy to install, allowing for selection based on 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 a large usable area. This allows growers to arrange planting and install equipment as needed. It is suitable for modern planting technologies and equipment, such as vertical cultivation and soilless cultivation, increasing land utilization and output.

Strong Environmental Control CapabilitiesEquipped 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 temperature, humidity, light, and carbon dioxide concentration, creating suitable conditions for crop growth, enabling year-round production and high-quality yields.

Good Insulation PerformanceDouble or multiple layers of covering material and good sealing measures are used to reduce heat loss and improve insulation. In winter, energy consumption and heating costs are effectively reduced; 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. Compared with single-span greenhouses, multi-span greenhouses have stronger wind and snow resistance. The frame structure is carefully designed and calculated to withstand significant external loads, offering better protection of crops and facilities in severe weather conditions such as typhoons and heavy snow.

Applications

Vegetable CultivationSuitable for cultivating various vegetables, such as tomatoes, cucumbers, and peppers. Precise environmental control enables out-of-season production and year-round supply, improving vegetable yield and quality to meet market demand.

Flower CultivationProvides a suitable growth environment for flowers, promoting their growth and development and improving quality and yield. It is often used for high-end flowers such as roses, lilies, and Phalaenopsis orchids, meeting market demand and also applicable to flower research and seedling cultivation.

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

Agricultural TourismWith its attractive appearance and diverse planting options, 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 experience the fun of agricultural production, driving local tourism development, and achieving organic integration of agriculture and tourism.

Covering Material

The top covering uses UV-resistant outer and anti-condensation inner layers of polycarbonate hollow panels. The surrounding walls use polycarbonate hollow panels or glass as per standard requirements. In some colder regions (Jilin, Heilongjiang, etc.), the north wall can use an insulating composite panel, and sliding windows can be installed to increase ventilation.

Technical Parameters

Wind load resistance: 0.6 KN/M2, 10 or greater wind speeds; snow load resistance: 0.5 KN/M2; greenhouse constant load: 15 KG/M2; maximum greenhouse rainfall: 140 MM/h.

Main Configurations

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

Greenhouse Specifications

Standard greenhouse specifications are 9.6 meters or 12.8 meters in span, 4 meters in width, 4.2 meters in eave height, and 5.2 meters in ridge height. The span and width can be adjusted according to user requirements.

Greenhouse Applications

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