Frequently Asked Questions About EPE Solar Encapsulant Film

What is the difference between EPE and EVA solar film?

EPE film has better low-temperature resistance and flexibility compared to traditional EVA film. While EVA film is suitable for conventional crystalline silicon modules, EPE film maintains excellent elasticity and adhesion even at -40°C, making it ideal for flexible solar modules, thin-film panels and applications in cold climates.

Can EPE solar film be used with flexible substrates?

Yes, that's one of the main advantages of EPE solar film. It has excellent flexibility and adhesion to various flexible substrates such as PET, ETFE and thin metal foils. It can be bent and folded repeatedly without cracking, making it perfect for flexible photovoltaic modules and portable solar products.

What is the minimum order quantity for custom EPE film?

For standard specification products, our MOQ is 3000 square meters. For customized products, the MOQ depends on your specific requirements, generally 10,000 square meters. We can also accommodate small trial orders for new customers to test our product quality.

How long is the service life of EPE solar film?

Our EPE solar encapsulant film is designed for a service life of 25+ years in outdoor environments. It has excellent UV resistance, weather stability and anti-aging properties, ensuring long-term reliable performance even in harsh climate conditions.

Do you provide technical support for lamination process?
