Sunlight panels greenhouses are products that replace the original plastic film greenhouses and glass greenhouses. They are mostly of the Venlo type (arch shapes can also be adopted), mostly using multi-span structures. They feature a modern appearance, stable structure, beautiful and generous form, smooth visuals, excellent insulation performance, moderate light transmittance, multiple rain gutters, large spans, large drainage capacity, and strong wind resistance, suitable for areas with relatively high wind and rainfall.

Structural Features

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

Covering MaterialsCommon covering materials include glass, polycarbonate panels, and plastic films. Glass offers good light transmittance and is aesthetically pleasing and durable; polycarbonate panels have strong insulation and high impact resistance; plastic films are lower in cost and easy to install, allowing for choices based on different needs and crops.

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

Performance Advantages

High Space Utilization RateThe interior has no or few columns, providing an open space with a large usable area. This allows growers to arrange planting and equipment installation 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 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 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 often employed to reduce heat loss and improve insulation. In winter, energy consumption and heating costs are effectively reduced. In summer, shading and ventilation measures provide effective cooling, maintaining the greenhouse temperature within a range suitable for crop growth.

Strong Disaster ResistanceThe overall structure is sturdy, and compared to single greenhouses, multi-span greenhouses offer stronger wind and snow resistance. The frame structure is carefully designed and calculated to withstand significant external loads, providing better protection for crops and facilities in severe weather conditions such as typhoons and blizzards.

Applications

Vegetable PlantingSuitable for growing various vegetables such as tomatoes, cucumbers, and peppers. Precise environmental control allows for 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 growth and development, improving flower quality and yield. Commonly used for growing high-end flowers such as roses, lilies, and Phalaenopsis, meeting the needs of the flower market, and also applicable for flower research and seedling cultivation.

Fruit PlantingSome 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 aesthetically pleasing 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. This also drives the development of local tourism, achieving an organic combination of agriculture and tourism.

Covering Materials

The top cover uses UV-resistant outer and anti-condensation inner layers of polycarbonate hollow panels. The surrounding walls are made of polycarbonate hollow panels or glass according to conventional requirements. Depending on regional climatic conditions, in some cold 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 higher wind speeds; Snow load resistance: 0.5 KN/M2; Greenhouse constant load: 15KG/M2; Maximum rainfall: 140MM/h.

Main Configurations

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

Greenhouse Specifications

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

Applications

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