What Matters in Solar Panel Manufacturing?
Weather Resistance
Solar module sealing materials should be evaluated for long-term exposure to sunlight, rain, moisture, ozone and outdoor environmental conditions.
Thermal Cycling
Flexible sealing materials should accommodate repeated expansion and contraction caused by temperature changes.
Moisture Protection
Sealing and potting can help protect module interfaces and electrical components against moisture ingress and contamination.
Electrical Protection
Potting and encapsulation materials can provide insulation and environmental protection for selected electrical assemblies.
Selecting the Right Material for Solar Module Assembly
A correct adhesive or sealant selection starts with the component, substrate and manufacturing process rather than the product name alone.
