Solar Back Sheet Performance Testing Solutions

Product catalog summary

Introduction to Solar Back Sheet
Solar back sheets are the outermost layer of photovoltaic (PV) modules, designed to protect the inner components, such as photovoltaic cells and electrical parts, from external stresses. They also serve as electrical insulators. Typically, these back sheets are robust three-layer laminates with high dielectric properties.

Key Properties of Solar Back Sheets

UV resistance
Moisture barrier
Mechanical properties
Strength and durability
Resistance to weathering
Electrical insulation
UL recognition

Moisture Barrier Property
The moisture barrier property of solar back sheets, which are made from fluoride and polyester films, is crucial. Labthink uses international standards like ISO 15106, ASTM F1249, and ASTM E96 to determine the water vapor transmission rate. Labthink's testing systems, including the W3/060 Water Vapor Permeability Tester, are designed for high accuracy and automation in gravimetric testing.

Mechanical Properties
Proper thickness and tensile strength are essential for solar back sheets. Labthink's CHY-CA Thickness Tester provides precise measurements with 0.1 micron accuracy and features an auto-feeding function for enhanced automation.

Strength and Durability
Labthink focuses on testing machines for flexible packaging, unlike most manufacturers who focus on rigid materials. Their tensile testers are specifically designed for plastic and laminated films, offering a test range up to 500N with high accuracy.

Solar Back Sheet Performance Testing Solutions-1

Labthink’s Customer Solutions for Solar Back Sheet Solar energy is inexhaustible and the cleanest source on earth. In one hour the sun delivers as much energy to the earth's surface as mankind consumes in one year. Solar energy is clean, sustainable, globally available, and does not harm the environment. What is Solar Back Sheet (PV Back Sheet)? The solar cell back sheet is the outermost layer of the PV module. The PV back sheet is designed to protect the inner components of the module, specifically the photovoltaic cells and electrical components from external stresses as well as act as an electric insulator. In order to accomplish this, the solar back sheet must be a robust construction, typically a three layer laminate, and have high dielectric properties. Properties of Solar Back Sheet UV resistance Moisture barrier Mechanical properties Strength and durability Resistance to weathering Electrical insulation UL recognized Labthink Customer Solutions for Solar Back Sheet Moisture Barrier Property Basically, solar back sheet is an encapsulate material which consists of fluoride and polyester film. How to determine the Moisture Barrier property of this kind of laminated films? ISO 15106 Plastics – Film and Sheeting – Determination of Water Vapour Transmission Rate, ASTM F1249 Water Vapor Transmission Rate Through Plastic Film and Sheeting Using a Modulated Infrared Sensor and ASTM E96 Water Vapor Transmission of materials by Cupping Method. Based on these international standards, Labthink designed the water vapor transmission rate testing systems based on different testing method, cup method, infrared Detection Method and Electronic Detection method. Labthink Instruments Company is professional in testing instruments of plastic film and laminated films with wide testing range and high testing accuracy.
