Application principles of solar greenhouses

For greenhouse cultivation, covering materials, greenhouse frames, greenhouse accessories, etc. are all important parts. We know that photosynthesis is required during plant growth, so when choosing covering materials, we must not only consider its warmth retention, wind and rain resistance, etc., but also its light transmittance. Sunshine panel greenhouses have appeared in people's sight in recent years, so what are the application principles of sun panel greenhouses?

PC solar panels commonly use a hollow two-layer structure. Compared with the three-layer and four-layer honeycomb rice-shaped structure, there is not much difference in other properties. The only difference is that structures such as four-layer honeycomb are stronger, thicker, and have increased thermal insulation performance per square meter. Well, of course it is stronger and naturally higher than a hollow two-layer structure.

Based on the actual situation of greenhouses in various places, in areas south of the Yangtze River, 8mm double-layer hollow PC solar panels can already meet the insulation requirements of local vegetable greenhouses. In North China, you can also use 8mm solar panels, but the greenhouse must have complete heating facilities. In the Northeast and Northwest regions, if the budget is sufficient, the insulation performance of the greenhouse built using three-layer or four-layer structure solar panels plus insulation facilities will be very good, but it is also possible to use ordinary double-layer solar panels, but in winter Heating equipment at night requires more energy to maintain heat in the greenhouse.

The commonly used thickness of greenhouse solar panels is 6mm-12mm, which is divided into double-layer boards and four-layer boards. The price per square meter of double-layer boards is about 20-44 yuan, and the price per square meter of four-layer boards is about 31-50 yuan.
