With the increasing support for agricultural transformation, more and more farmers have begun to get involved in the greenhouse industry, or grow high-value vegetables and fruits, or do agricultural picking, ecological restaurants and so on. Traditional film greenhouses are gradually abandoned, and PC solar panels are increasingly used in greenhouses. So, why should the greenhouse be covered with PC sun panels?
In fact, in the selection of greenhouse covering materials, it is mainly based on the following irreplaceable advantages of solar panels:
First, good light transmission
PC panel greenhouse is a lighting building, so the construction of PC panel greenhouse needs to have good light transmission*, light transmittance is a basic indicator to evaluate the light transmittance of the greenhouse. Light transmittance refers to the percentage of light penetrating into the greenhouse to the amount of outdoor light. The light transmittance of the greenhouse is affected by the light transmittance of the greenhouse light transmission covering material and the shadow rate of the greenhouse skeleton, and the light transmittance of the greenhouse changes at any time with the different solar radiation angles in different seasons.
The level of greenhouse transmittance has become a direct factor in crop growth and the selection of crop varieties, and the light transmittance of PC solar panels can be comparable to glass, * the light transmittance of solar panels can reach more than 85%.
Second, good thermal insulation performance
Sunshine panel greenhouse should pay attention to thermal insulation performance, improve the thermal insulation performance of the greenhouse, reduce energy consumption, is a more direct means to improve the efficiency of greenhouse production. The insulation ratio of the greenhouse is a basic indicator to measure the insulation performance of the greenhouse. The greenhouse insulation ratio refers to the ratio of the coverage area of greenhouse light transmission materials with small thermal resistance to the sum of the area covered by the greenhouse envelope with large thermal resistance. The larger the insulation ratio, the better the insulation performance of the greenhouse. Due to its special hollow structure, PC hollow solar panel has superior thermal insulation performance and is more practical in greenhouse projects.
Third, good durability
PC sun panel greenhouse construction must consider its durability, the traditional film greenhouse may have to be replaced a year, but PC sun panel quality warranty up to ten years, more than ten years is not a problem, greatly help customers save the time and labor of replacing covering materials.
