Photovoltaic Backplane
Photovoltaic backplane sheet - made by hot pressing composite of multi-layer glass fiber reinforced PP prepreg tape. In order to improve the appearance quality and certain functional layers, functional materials can be composite on the upper and lower surfaces (such as coating process, adhesive composite process, or hot pressed composite functional film). The unit area mass of continuous fiberglass impregnated reinforced PP unidirectional tape is 245-450g/㎡, with a glass fiber content of 60-70%. The specific structure and unit area mass can be designed according to the requirements of the photovoltaic panel.
PRODUCT CHARACTERISTICS
Lightweight and high-strength：Replacing traditional glass with continuous glass fiber reinforced PP sheets for laminated packaging can achieve the characteristics of "softness, thinness, and beauty". The thickness of the 0.45mm sheet is only 750gsm per unit area.
Cost reduction：The material cost is relatively lower compared to PET materials or fiberglass fabric materials, and it compresses the costs of purchasing, handling, packaging, and transportation of metals and glass in photovoltaic systems.
The basic performance fully meets the requirements：The product design can meet the requirements of component waterproofness, UV resistance, waterproofness, UV resistance, and heat oxidative aging resistance: the tensile strength retention rate of 160 ℃ -30 days is ≥ 50%. Compared to other materials, continuous fiber thermoplastic composites have good toughness while also possessing a certain degree of rigidity.
Easy to install：Unlike traditional photovoltaic modules that require piercing the connection between the roof and purlins during installation, the use of thermoplastic backboards for component adhesive installation can achieve a rootless and zero penetration installation effect. This not only saves a lot of labor costs and 40% of engineering time, but also does not affect the waterproof function of the roof due to penetration.
