Let’s go on exploring more fun in the lamination process of encapsulating solar PV modules. The 5th-lite Generation silicone rubber sheet comes up.

Silicone Rubber Membrane (5th-lite Gen)

Deer Hunter, a prominent innovator in the field of silicone rubber products making, is specialized in the production of ultra EVA resistant diaphrams for the lamination of solar photovoltaic panels. In direct response to the particular needs of the solar industry, we developed the 5th-lite Generation silicone rubber membranes for solar laminators. Due to the fluorine laminated layer and additional fabric reinforcement in the middle, it has good Eva resistant ability. As one of premier silicone membrane suppliers in China, our expertise in high temperature silicone sheets makes us an invaluable partner for solar panel industry, forging lasting connections with them.

Product Overview

Deer Hunter is making efforts to enhance and improve the production technology of solar panels around the world. With the 5th-lite Gen, they have crafted a highly effective solution for resistance against EVA-outgassing deterioration that has been utilized by top makers of both thin films and crystalline solar panels. Proud of our achievements thus far, we are dedicated to further exploring our potential capabilities to create superior silicone rubber sheets for photovoltaic modules encapsulation and bring more innovation into solar panel industry.

Structure

The 5th-lite Gen silicone sheet is an extraordinary type of rubber sheets, specially developed rubber membrane consisting of a silicone backing material and a unique covering layer. Look at the right image to get a clear view of its structure.

The black covering layer combined with the gray silicone ensures good eva resistant ability and good life cycle performance even in the most critical applications.

Solar Silicone Membrane FAQs

Before sending an official inquiry to us, you may have some doubts about silicone sheet for solar PV panels laminating machine. Here we list the most common RFQ for you.

1. Is your silicone sheet with or without a splice?

In our factory our super-wide calandars ensure that you can install our silicone membranes with no seam marks visible on the back sheet to produce solar PV panels. More and more customers are placing our membrane sheet in the process of solar photovoltaic modules lamination.

2. Is the membrane’s surface finish smooth/smooth or smooth/textured?

We find the question of surface finishes interesting – but in conclusion, we see no evidence that one option is better than another. Common sense says that a fabric impression will provide a natural venting path to aid release, especially in hot/sticky conditions. Most of our customers do prefer fabric impression 1 side and smooth 1 side. The physical properties of the material will be exactly the same irrespective of colour or surface finish – these do not change.

3. What can we do to extend the life of our sheet?

What we can do to extend the life of our sheet? A layer of PTFE coated fiberglass faric sheet resistant to high temperatures between the pv panels and the membrane is often suggested, Usually, the thickness can be 0.25mm or 0.35mm.

4. What’s the best rubber sheeting for solar photovoltaic modules lamination?

This is really a vital question and can be best discussed together face-to-face. There is no one answer that is right for everybody. There are many determining factors that can affect the choice of silicone diaphragm for example type of encapsulant, the composition of the modules, size of the modules, the brand of laminator, and budget constraints, etc. Our products enjoy strong customer loyalty thanks to their first-rate value. Customers are delighted by the very competitive pricing that allows them to get more for their money.

5. How long should a membrane sheet last?

Commonly our data shows that The 2nd Gen upto 4,000cycles and The 5th Gen upto 10,000 cycles. Good life cycle performance under controlled environments, such as humans, temperature, laminating machine, etc. As there are a number of variables beyond our direct control, it is very difficult to “guarantee” an exact cycle life.

6. What is your standard package?

For 1-5 pcs, standard package is woven bags. When quantity is over 5pcs, they will be rolled inside a cardboard tube and then put onto pallets or into wooden cases. We will listen to our customers carefully. When you get the cargo, please unfold it to check if there is any damage on the surface.

7. Does color have any impact on membrane performance?

Based on feedback from customers worldwide, we can see no advantage or disadvantage of different colors. Actually, colors are now used to differentiate between suppliers.

8. How to store silicone rubber membranes correctly?

After goods inward inspection of membranes upon receipt, we suggest you store inside the packaging. We suggests that storage temperature should be below 25°C and products should be stored away from direct sources of heat such as boilers, radiators and direct sunlight.

9. How can we tell the difference of Deer Hunter solar silicone sheets?

As technology progresses, there are three types of silicone membranes for the solar industry. Please check or download below technical data sheet for your further distinction.
