Solar panel greenhouse

Sunshine greenhouses are mostly Wenluo type (can also be round arched), mostly adopting a span and multiple tops, modern appearance, stable structure, beautiful appearance, smooth visual, good thermal insulation performance, moderate light transmittance, multi-rain trough, large Span, large displacement, strong wind resistance, suitable for areas with high wind and rainfall. Sunlight greenhouse has good transparency and low heat transfer coefficient. Due to the light weight of the solar panel, long life and high tensile strength, it can meet the requirements of wind and snow resistance through simple steel structure, and has a long life and beautiful appearance. Generous, reducing duplication of construction and investment, is currently replacing the original plastic film greenhouse and glass greenhouse products

main structure

The main body of the greenhouse mainly includes columns, rafters, side rails, arches, truss trusses, rain gutters (gutters), connecting parts, aluminum profiles, seals, seals, fasteners, etc.

Covering material

The inner layer is anti-condensed polycarbonate hollow board, and the surrounding wall is made of polycarbonate hollow board or glass according to the conventional requirements. According to the difference of regional climatic conditions, in some cold areas (Jilin, Heilongjiang, etc.), the north wall can be The insulation composite board can also be used to install sliding windows to increase the greenhouse ventilation area.

The sun board has the following characteristics

(1) Transmittance: The transmittance of P C solar panel is as high as 89%, which is comparable to glass. UV-coated panels do not produce yellowing under sunlight, and fogging, poor light transmission, after 10 years, the loss of light transmission is only 10%, the rate of PVC loss is as high as 15%-20%, and the fiberglass is 12 %-20%.

(2) Anti-collision: the impact strength is 250-300 times that of ordinary glass, 30 times of acrylic glass of the same thickness, 2-20 times of tempered glass, and there is no crack when it is dropped by 2 meters below 3kg hammer. The name of “glass” and “sound steel”.

(3) UV protection: The PC board is coextruded with anti-ultraviolet (UV) coating on one side and anti-condensation treatment on the other side. It is resistant to UV, heat and anti-fog. It blocks UV rays and protects valuable artwork and exhibits from UV damage.

(4) Light weight: The specific gravity is only half of the glass, saving the cost of transportation, handling, installation and support frame.

(5) Flame retardant: PC board's own ignition point is 580 °C, self-extinguishing from the fire, no toxic gas will be produced during combustion, and will not promote the spread of fire.

(6) Flexibility: It can be installed in an arched, semi-circular top and window according to the design drawing. The small bending radius is 175 times the thickness of the plate, and it can also be bent.

(7) Sound insulation: P C solar panel sound insulation, better acoustic insulation than glass and acrylic sheets of the same thickness. Under the same thickness, the sound insulation of P C solar panel is 5-9DB higher than that of glass.

(8) Energy-saving: cool in summer, heat in winter, PC solar panel has lower thermal conductivity (K value) than ordinary glass and other plastics, heat insulation effect is 7%-25% higher than equivalent glass, PC sunshine board Insulation to 49%. Therefore, the heat loss is greatly reduced, and the building used for the heating equipment is an environmentally friendly material.

(9) Temperature adaptability: PC board does not appear cold-brittle at -40 °C, does not soften at 125 °C, and its mechanical and mechanical properties do not change significantly in harsh environments.

(10) Weather resistance: P C solar panels can maintain the stability of various physical indexes in the range of -40 ° C to 120 ° C. The artificial climate aging test was 4000 hours, the yellowing degree was 2, and the light transmittance reduction value was only 0.6%.

(11) Anti-condensation: The outdoor temperature is 0 ° C, the indoor temperature is 23 ° C, and the indoor relative humidity is less than 80%, the inner surface of the material does not condense. The dew will flow away from the surface of the board and will not drip.

(12) Simple and convenient, not as bulky as traditional materials, it has been applied to coastal cities in China in recent years.
