What are the benefits of using solar panels as covering materials in greenhouses

 What are the obvious applications of solar panels in vegetable production? First of all, it can increase the output value and achieve the effect of increasing production and income. For the planting of high value-added economic crops such as Chinese herbal medicine, it has an excellent protective effect from seedling cultivation to large-scale production. The reasonable matching of auxiliary greenhouse facilities can achieve twice the result with half the effort. Secondly, because the thermal insulation effect of solar panels is much higher than that of other materials such as glass, it can reduce the energy consumption of greenhouses and at the same time enable crops to grow in a more suitable environment and improve the quality and nutritional content of crops. Focus on greenhouse engineering technology and serve modern agriculture. The article was published by Manager Zhang of Guangyuan Greenhouse. If you are dedicated, please keep the source.

Type: Sunshine panels are divided into rectangular panels, rice-shaped panels, honeycomb panels, lock panels, etc. in terms of structure. From the board type, it is divided into double-layer board and multi-layer board. Double-layer rectangular sun panels are commonly used in general lighting and shading fields. Among them, the greenhouse covering material mainly adopts 4~12mm transparent sunlight board, which has the characteristics of high light transmittance, good thermal insulation performance, light specific gravity, and high cost performance. Multi-layer panels are mainly used in large-scale stadiums, railway stations and other heavy steel structures, which are characterized by large specific gravity and good structural mechanics design bearing performance. According to the number of years, it is divided into 3-year boards and 5-year boards. The quality assurance of high-quality sun board manufacturers can reach 10 years. The current production process of solar panels is very mature, and the production technology and quality control are becoming more and more standardized. The current production process is mainly based on the extrusion process, and the main production equipment used is divided into two types: imported and domestic.

Transparent roof sheet Advantages: The light transmittance of the solar panel can reach up to 89%, which is comparable to that of glass. UV-coated boards will not produce yellowing, fogging, and poor light transmission when exposed to sunlight. After 10 years, the light transmission loss is only 6%, while the light transmission loss rate of polyvinyl chloride (PVC) boards is as high as 15%. ~20%, glass fiber is 12%~20% PC board impact strength is 250~300 times that of ordinary glass, 30 times that of acrylic board of the same thickness, 2~20 times that of tempered glass, has "unbreakable glass" and The reputation of "sound steel". At the same time, the specific gravity is only half of that of glass, which saves the cost of transportation, handling, installation and support frame. Therefore, PC boards are mainly used in fields that have high requirements for both light transmittance and impact, such as greenhouses, outdoor light boxes, shields, etc.

One side of the sunshine board is coated with anti-ultraviolet (UV) coating, and the other side is treated with anti-condensation. It integrates anti-ultraviolet, heat insulation and anti-drip functions, and can block ultraviolet rays from passing through. It is suitable for protecting precious artworks and exhibits from Damaged by ultraviolet rays: There are also PC boards made of double-sided UV special technology, which are suitable for special flower planting and environments with higher requirements for UV protection. Confirmed by the national standard GB50222-95, the sun panel is the first class of flame retardant, that is, B1 class. The ignition point of the PC board itself is 580°C, and it will self-extinguish after leaving the fire. It will not produce toxic gas when burning, and will not promote the spread of the fire.

FRP Panel manufacturers have gradually become one of the main fireproof materials for large daylighting buildings. And according to the design drawing, the cold bending method can be used on the construction site to install arched, semicircular roofs and windows. The minimum bending radius is 175 times the thickness of the plate used, and it can also be hot bent. In the fields of greenhouses with radian design and architectural decoration, the strong plasticity of PC boards has been widely used.

The sound insulation effect of the sun board is obvious, and it has better sound insulation than the glass and acrylic board of the same thickness. Under the same thickness, the sound insulation of the sun board is 34dB higher than that of the glass, and it is the first choice for international highway noise barriers. Keep cool in summer and keep warm in winter. PC board has lower thermal conductivity (K value) than ordinary glass and other plastics. The heat insulation effect is 7%~25% higher than that of glass of the same thickness. The heat insulation of PC board is up to 49%. . As a result, the heat loss is greatly reduced, and it is an environmentally friendly material used in buildings with heating equipment.

FRP lighting tile can maintain the stability of various physical indicators in the range of -40~120°C. It does not become cold and brittle at -40°C, does not soften at 125°C, and has no significant changes in its mechanical and mechanical properties in harsh environments. After 4000 hours of artificial weathering test, the degree of yellowing is 2, and the decrease of light transmittance is only 0.6%. When the outdoor temperature is 0°C, the indoor temperature is 23°C, and the indoor relative humidity is lower than 80%, the inner surface of the material will not condense.
