Sunlight panel greenhouses are replacements for traditional plastic film and glass greenhouses. They are mostly 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. They are suitable for regions with high winds and rainfall.

Structural Features

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 MaterialsCommon 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 different needs and crops.

Frame MaterialHot-dip galvanized steel pipes or aluminum alloy 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 UtilizationThe interior is free of or has minimal columns, resulting in an open space and a large usable area. This allows growers to arrange plantings and install equipment according to their needs. It is suitable for modern cultivation techniques and equipment such as vertical cultivation and soilless cultivation, increasing land use efficiency and output.

Strong Environmental Control CapabilitiesEquipped with an advanced environmental control system, including ventilation, shading, heating, cooling, and irrigation systems. Through the coordinated operation of these systems, the temperature, humidity, light, and carbon dioxide concentration inside the greenhouse can be precisely regulated, 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 minimize 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 sturdy. 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, better protecting crops and facilities in harsh weather conditions such as typhoons and blizzards.

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 growing environment for flowers, promoting their growth and development, and improving quality and yield. Often used for high-end flowers like roses, lilies, and Phalaenopsis, meeting market demand. It can also be used 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. By adjusting temperature, humidity, and light conditions, fruit growth and ripening are promoted, improving yield and quality, and extending the harvesting 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. This can also drive local tourism development, achieving an organic combination of agriculture and tourism.

Covering Materials

The roof covering uses UV-resistant outer layer and anti-condensation inner layer polycarbonate hollow panels. The surrounding walls are made of polycarbonate hollow panels or glass according to conventional requirements. In colder regions (such as Jilin and Heilongjiang), the north wall may use an insulating composite panel, and sliding windows can be installed to increase greenhouse ventilation.

Technical Parameters

Wind load resistance: 0.6KN/M2, 10 or greater wind speed; snow load resistance: 0.5 KN/M2; greenhouse constant load: 15KG/M2; maximum greenhouse rainfall: 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 have a span of 9.6 meters or 12.8 meters, a bay width of 4 meters, an eave height of 4.2 meters, and a ridge height of 5.2 meters. Span and bay width can be adjusted according to user requirements.

Greenhouse Applications

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