The polycarbonate panel (PC panel, PC sheet) greenhouse is a kind of greenhouse with polycarbonate (PC) panels as the main covering material. Polycarbonate panels are engineering plastics with excellent comprehensive properties, having many advantages such as good light transmittance and impact resistance, and are widely used in the field of greenhouse construction.

Frame Structure:

The frames of PC panel greenhouses are generally made of hot-dip galvanized light steel or aluminum alloy. The hot-dip galvanized light steel frames are sturdy and durable, with good load-bearing capacity, capable of supporting the weight of the PC panels and the internal facilities of the greenhouse. Aluminum alloy frames, on the other hand, are lightweight, aesthetically pleasing, and corrosion-resistant, which are convenient for installation and disassembly and have a relatively long service life.

The design of the frames usually takes into account the local climate conditions and the functions of the greenhouse. For example, in regions with heavy snow and strong winds, the spacing between the frames will be appropriately reduced to enhance the overall wind and snow resistance of the greenhouse.

Covering Materials:

The thickness of PC panels generally ranges from 4 to 16 mm, with 8 mm and 10 mm being common. It has a hollow structure, which endows the PC panels with good thermal insulation properties. For instance, its heat insulation effect is better than that of ordinary glass greenhouses, effectively reducing heat transfer and minimizing heat loss in the greenhouse at night.

PC panels have a high light transmittance, reaching around 80% - 90%, which is similar to that of glass. Moreover, they have a relatively low ultraviolet transmittance, which helps protect the indoor plants from excessive ultraviolet damage. At the same time, PC panels also have impact resistance, which is 250 - 300 times that of ordinary glass, making them less likely to be damaged by external forces such as hail.

Temperature Regulation:

PC panel greenhouses can effectively maintain the indoor temperature. During the day, sunlight penetrates the PC panels into the greenhouse, raising the indoor temperature. At night, its good thermal insulation performance can reduce heat dissipation, thus creating a relatively stable temperature environment. For example, in the northern winter, with appropriate auxiliary heating equipment, PC panel greenhouses can provide a suitable growth temperature for plants.

Lighting Environment:

Thanks to its high light transmittance, it can provide sufficient light for plants, ensuring the normal progress of photosynthesis. In addition, its light-scattering effect is better than that of glass, which makes the indoor light distribution more uniform, reduces the shaded areas during plant growth, and is conducive to the even growth of plants.

Resistance to Natural Disasters:

Due to the good impact resistance of PC panels, the risk of damage to the greenhouse is relatively low when facing natural disasters such as hail and strong winds. For example, in areas frequently hit by hail, PC panel greenhouses can effectively protect the internal plants from damage.

I. Agricultural Cultivation Field

Vegetable Cultivation:
PC panel greenhouses provide a suitable growth environment for vegetables. Many vegetable varieties, such as tomatoes, cucumbers, and lettuce, have strict requirements for temperature, light, and humidity. In PC panel greenhouses, these environmental factors can be precisely controlled by adjusting systems such as ventilation, shading, and irrigation.

Flower Cultivation:
Flowers have even more stringent requirements for the growth environment. PC panel greenhouses can create a suitable microclimate according to the needs of different flower varieties. For light-loving flowers like roses, they can receive sufficient and uniform light in PC panel greenhouses, optimizing the color and petal texture of the flowers.

Seedling Raising:
During the seedling stage, seedlings are very sensitive to environmental changes. PC panel greenhouses can provide stable temperature and light conditions, which are conducive to the germination of seeds and the healthy growth of seedlings.

II. Leisure Agriculture Field

Eco-restaurants:
The eco-restaurants built with PC panel greenhouses combine natural landscapes with the dining environment. Their good light transmittance makes the interior of the restaurant bright and airy. Customers can enjoy delicious food while admiring the surrounding green plant landscapes.

Tourist Greenhouses:
As tourist greenhouses, PC panel greenhouses can display various rare plants, tropical plants, or characteristic agricultural planting patterns. Tourists can stroll inside the greenhouse, observe the growth forms of plants up close, and learn about agricultural knowledge.
