Sunlight panel greenhouses are a replacement for traditional plastic film and glass greenhouses. They are mostly of the Venlo type (arch type is also available), mostly using multi-span roofs. They have a modern appearance, stable structure, beautiful and generous form, smooth visual effect, excellent heat preservation performance, moderate light transmittance, multiple rain gutters, large span, large drainage capacity, and strong wind resistance, suitable for areas with relatively large 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 internal space of the greenhouse more spacious and open, facilitating large-scale agricultural production and mechanized operations.

Covering MaterialsCommonly used covering materials include glass, polycarbonate panels, and plastic films. Glass has good light transmission and is beautiful and durable; polycarbonate panels have strong heat insulation and high impact resistance; plastic films are relatively low in cost and easy to install, and can be selected according to different needs and crops.

Frame MaterialsHot-dip galvanized steel pipes or aluminum alloys are mostly used, which have good strength and corrosion resistance, can withstand large wind and snow loads, and ensure the stability and safety of the greenhouse structure.

Performance Advantages

High Space Utilization RateThere are no or few internal columns, resulting in an open space with a large usable area. This allows growers to arrange planting and equipment installation according to their needs. It is suitable for using modern planting technologies and equipment such as three-dimensional 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. Through the coordinated work of these systems, the temperature, humidity, light, and carbon dioxide concentration inside the greenhouse can be precisely adjusted, creating suitable conditions for crop growth, and achieving year-round production and high-quality output.

Good Heat Preservation PerformanceDouble or multi-layer covering materials and good sealing measures are used to reduce heat loss and improve heat preservation. In winter, it can effectively reduce energy consumption and heating costs; in summer, through shading and ventilation measures, it also has a good cooling effect, keeping the greenhouse temperature within a range suitable for crop growth.

Strong Disaster ResistanceThe overall structure is strong, and compared to single greenhouses, multi-span greenhouses have stronger wind and snow resistance. Its framework structure has been carefully designed and calculated to withstand large external loads. Under harsh weather conditions such as typhoons and blizzards, it can better protect crops and facilities.

Applications

Vegetable PlantingIt can be used to grow various vegetables, such as tomatoes, cucumbers, and peppers. Through precise environmental control, it achieves the off-season production and year-round supply of vegetables, improves vegetable yield and quality, and meets market demand.

Flower CultivationProvides a suitable growth environment for flowers, which is beneficial to the growth and development of flowers, improving flower quality and yield. It is often used to grow high-end flowers such as roses, lilies, and Phalaenopsis, meeting the needs of the flower market, and can also be used 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 the temperature, humidity, and light conditions in the greenhouse, it promotes the growth and maturation of fruits, improves fruit yield and quality, and can extend the picking period.

Agricultural TourismWith its beautiful appearance and rich planting content, multi-span greenhouses are often used in agricultural tourism projects. They can be built into agricultural tourism parks, ecological restaurants, science education bases, etc., attracting tourists to visit and experience the fun of agricultural production. At the same time, it can drive the development of the local tourism industry and achieve an organic combination of agriculture and tourism.

Covering Materials

The top 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. According to the differences in regional climate conditions, in some cold areas (Jilin, Heilongjiang, etc.), the north wall can use insulated composite panels, and sliding windows can also be installed to increase the ventilation area of the greenhouse.

Technical Parameters

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

Main Configurations

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

Greenhouse Specification

The conventional specification of the greenhouse is 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. The span and bay width can be adjusted and designed according to user requirements.

Greenhouse Applications

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