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, aesthetically pleasing 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 Features

Connection MethodMultiple individual greenhouses are connected via gutters and other components to form a continuous large-scale 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 relatively low-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 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, improving 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 within the greenhouse, creating suitable conditions for crop growth, enabling year-round production and high-quality yields.

Good Insulation PerformanceDouble or multiple layers of covering materials and effective 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 measures provide good cooling, keeping the greenhouse temperature within a range suitable for crop growth.

Strong Disaster ResistanceThe overall structure is robust, and compared to 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. In severe weather conditions, such as typhoons and blizzards, it better protects crops and facilities.

Applications

Vegetable CultivationSuitable for cultivating various vegetables such as tomatoes, cucumbers, and peppers. Precise environmental control enables counter-seasonal 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. Commonly used for cultivating high-end flowers such as roses, lilies, and Phalaenopsis, meeting market demand and also suitable for flower research and seedling cultivation.

Fruit CultivationSome fruits with high environmental requirements, such as strawberries and blueberries, can also be grown in multi-span greenhouses. By adjusting temperature, humidity, and light conditions within the greenhouse, fruit growth and maturation are promoted, improving yield and quality, and extending the harvesting period.

Agricultural TourismWith its attractive appearance and rich 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, while also driving the development of local tourism and achieving an organic combination of agriculture and tourism.

Covering Material

The roof covering uses a UV-resistant outer layer and a dew-proof inner layer of polycarbonate hollow panels. The surrounding walls are made of polycarbonate hollow panels or glass according to conventional requirements. In some colder regions (Jilin, Heilongjiang, etc.), the north wall can use insulated composite panels, and sliding windows can be installed to increase the greenhouse ventilation area.

Technical Parameters

Wind load resistance: 0.6KN/M2, 10 or greater wind speeds; snow load resistance: 0.5 KN/M2; greenhouse constant load: 15KG/M2; maximum greenhouse drainage: 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 system, infrared heating system, etc.

Greenhouse Specification

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. Span and width can be adjusted according to user requirements.

Greenhouse Applications

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